服务发现
基于文件的服务发现
现有配置：
[root@mcw03 ~]# cat /etc/prometheus.yml # my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds.

把static_configs 替换成file_sd_configs
配置刷新重载文件配置的时间。可以不用手动刷新
创建目录并修改配置，指定使用的文件配置
下面红色配置错了，直接指定文件路径就可以，不需要targets键

重载之后正常，
从标签里可以看到，服务自动发现来自哪里
因为target是yml或者json数据，所以可以用salt，cmdb等等各种，进行配置集中管理，实现监控
基于文件的自动发现，添加标签的实现
修改配置
[root@mcw03 ~]# vim /etc/targets/nodes/nodes.json [root@mcw03 ~]# cat /etc/targets/nodes/nodes.json [{ "targets": [ "10.0.0.14:9100", "10.0.0.12:9100" ], "labels": { "datacenter": "mcwhome" } }] [root@mcw03 ~]# vim /etc/targets/docker/daemons.yml [root@mcw03 ~]# cat /etc/targets/docker/daemons.yml - targets: - "10.0.0.12:8080" - labels: "datacenter": "mcwymlhome" [root@mcw03 ~]#
不需要重启服务，这个标签自动就有了。不过yml格式的，添加标签，没有生效。不清楚咋添加
基于api的服务发现
基于dns的服务发现

在Prometheus配置里面添加配置。修改前是这样的
# Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: # - alertmanager:9093
修改后是这样的.也可以用主机名代替ip，不过需要本机可以解析
# Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: - 10.0.0.14:9093
重载之后查看是否生效了

配置alertmanager
默认配置
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml route: group_by: ['alertname'] group_wait: 30s group_interval: 5m repeat_interval: 1h receiver: 'web.hook' receivers: - name: 'web.hook' webhook_configs: - url: 'http://127.0.0.1:5001/' inhibit_rules: - source_match: severity: 'critical' target_match: severity: 'warning' equal: ['alertname', 'dev', 'instance'] [root@mcw04 ~]# ss -lntup|grep 5001 [root@mcw04 ~]#
修改配置如下
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:25' smtp_from: '13xx2@163.com' smtp_auth_username: '13xx32' smtp_auth_password: 'xxx3456' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: receiver: email receivers: - name: 'email' email_configs: - to: '8xx5@qq.com' [root@mcw04 ~]#
创建目录，
[root@mcw04 ~]# sudo mkdir -p /etc/alertmanager/template
重启一下
[root@mcw04 ~]# systemctl restart alertmanager.service
查看配置，
已经修改为如下：下面的配置，没有在配置文件出现的，我们看情况应该也可以修改

添加报警规则
添加第一条告警规则
修改前
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: - "rules/node_rules.yml" # - "first_rules.yml" # - "second_rules.yml"
修改后
[root@mcw03 ~]# vim /etc/prometheus.yml # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: - "rules/*_rules.yml" - "rules/*_alerts.yml"
这是之前添加的记录规则
[root@mcw03 ~]# cat /etc/rules/node_rules.yml groups: - name: node_rules interval: 10s rules: - record: instance:node_cpu:avg_rate5m expr: 100 - avg(irate(node_cpu_seconds_total{job='agent1',mode='idle'}[5m])) by (instance)*100 - record: instace:node_memory_usage:percentage expr: (node_memory_MemTotal_bytes-(node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes))/node_memory_MemTotal_bytes*100 labels: metric_type: aggregation name: machangwei - name: xiaoma_rules rules: - record: mcw:diskusage expr: (node_filesystem_size_bytes{mountpoint="/"}-node_filesystem_free_bytes{mountpoint="/"})/node_filesystem_size_bytes{mountpoint="/"}*100 [root@mcw03 ~]#
修改上面的配置，重载之后，记录规则没有啥影响
告警的配置，需要用到第一个记录规则
编辑告警配置文件。HighNodeCPU是告警的名称，expr下面可以用指标或者记录规则，使用运算符来指定触发阈值，
[root@mcw03 ~]# ls /etc/rules/ node_rules.yml [root@mcw03 ~]# vim /etc/rules/node_alerts.yml [root@mcw03 ~]# cat /etc/rules/node_alerts.yml groups: - name: node_alerts rules: - alert: HighNodeCPU expr: instance:node_cpu:avg_rete5m > 80 for: 60m labels: servrity: warning annotations: summary: High Node CPU for 1 hour console: You might want to check the Node Dashboard at http://grafana.example.com/dashboard/db/node-dashboard [root@mcw03 ~]# ls /etc/rules/ node_alerts.yml node_rules.yml [root@mcw03 ~]#
重载
[root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload
重载之后，刷新告警页面，点击绿色的地方
可以看到我们定义的告警规则
触发告警，以及配置邮件告警
下面触发告警，调低阈值 ，for改为10s，上面的记录规则写错了，修改正确，由rete改为rate ,并且触发阈值是大于1就触发告警，重载配置
[root@mcw03 ~]# vim /etc/rules/node_alerts.yml [root@mcw03 ~]# cat /etc/rules/node_alerts.yml groups: - name: node_alerts rules: - alert: HighNodeCPU expr: instance:node_cpu:avg_rate5m > 1 for: 10s labels: servrity: warning annotations: summary: High Node CPU for 1 hour console: You might want to check the Node Dashboard at http://grafana.example.com/dashboard/db/node-dashboard [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
从表达式浏览器这里可以看到，有个机器是可以触发告警阈值的
alert这里，显示有个活跃的告警，之前是0活跃的绿色
点击打开之后，可以看到相关触发告警的信息
alertmanager页面，也可以看到这个告警
点击信息，可以看到我们告警规则里面注册的信息
点击来源的时候
跳转到Prometheus的浏览器表达式地址，我们给笔记本添加这个主机的解析记录
添加解析记录之后，刷新一下页面可以看到是这样的
又过了一阵子，查看状态已经变化了
没有看到发送邮件，查看报错，域名解析有问题

[root@mcw04 ~]#
修改配置如下：
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '自己邮箱@163.com' smtp_auth_username: '自己邮箱32@163.com' smtp_auth_password: '自己的smtp授权密码' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: receiver: email receivers: - name: 'email' email_configs: - to: '8发送给那个邮箱5@qq.com' [root@mcw04 ~]#
然后重启alertmanager才算成功发送邮件
告警信息如下
对比如下，把注册信息，还有下面触发后的标签发送出去了，我们自己顶一顶额标签告警级别也有
参考邮件alertmanger配置
参考：https://blog.csdn.net/qq_42527269/article/details/128914049
global: resolve_timeout: 5m smtp_smarthost: 'smtp.163.com:465' smtp_from: '自己邮箱@163.com' smtp_auth_username: '自己邮箱@163.com' smtp_auth_password: 'PLAPPSJXJCQABYAF' smtp_require_tls: false templates: - 'template/*.tmpl' route: group_by: ['alertname'] group_wait: 30s group_interval: 5m repeat_interval: 20m receiver: 'email' receivers: - name: 'email' email_configs: - to: '接收人邮箱@qq.com' html: '{{ template "test.html" . }}' send_resolved: true
添加新警报和模板，获取标签值，指标值
annotations: summary: Host {{ $labels.instance }} of {{ $labels.job }} is up! myname: xiaoma {{ humanize $value }}
将原来的告警配置文件移动成告警2配置文件，重载
[root@mcw03 ~]# mv /etc/rules/node_alerts.yml /etc/rules/node_alerts2.yml [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
文件没匹配上
重新改名
[root@mcw03 ~]# ls /etc/rules/ node_alerts2.yml node_rules.yml [root@mcw03 ~]# mv /etc/rules/node_alerts2.yml /etc/rules/node2_alerts.yml [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
刷新一下，之前消失的数据又回来了，并且触发告警，发送邮件通知了
新增同样的文件，然后写两个告警配置文件。
注解中要使用标签，需要用引用变量的方式，从$labels里面获取
[root@mcw03 ~]# vim /etc/rules/node_alerts.yml [root@mcw03 ~]# cat /etc/rules/node_alerts.yml groups: - name: node_alerts rules: - alert: DiskWillFillIn4Hours expr: predict_linear(node_filesystem_free_bytes{mountpoint="/"}[1h],4*3600) < 0 for: 5m labels: severity: critical annotations: summary: Disk on {{ $labels.instance }} will fill in approximately 4 hours - alert: InstanceDown expr: up{job="node"} == 0 for: 10m labels: severity: critical annotations: summary: Host {{ $labels.instance }} of {{ $labels.job }} is down! [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
查看页面，已经生成了两个警报规则
修改磁盘使用预测的值，将0改为102400000000，将for 改为10s ，触发告警
[root@mcw03 ~]# vim /etc/rules/node_alerts.yml [root@mcw03 ~]# cat /etc/rules/node_alerts.yml groups: - name: node_alerts rules: - alert: DiskWillFillIn4Hours expr: predict_linear(node_filesystem_free_bytes{mountpoint="/"}[1h],4*3600) < 102400000000 for: 10s labels: severity: critical annotations: summary: Disk on {{ $labels.instance }} will fill in approximately 4 hours - alert: InstanceDown expr: up{job="node"} == 0 for: 10m labels: severity: critical annotations: summary: Host {{ $labels.instance }} of {{ $labels.job }} is down! [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
可以看到，这个警报规则触发了四个告警，并发送了邮件
并且四条告警是一起发送出来的，都把标签和注解作为邮件内容发送出来了。而且使用标签变量的部分，都是渲染对应告警机器的标签值了
改回去之后，告警取消
根据标签过滤一下
报错了
修改下job,是docker的，修改下表达式是，结果是1的就触发告警。修改时间for是10s。添加注解，注解中获取表达式的值，值是1
然后看邮件发送的结果，可以看到，所有的告警，都汇总到一个邮件里面了，并且获取到表达式的值，在注解中
注解中获取到表达式值为1
获取表达式的值
[root@mcw03 ~]# cat /etc/rules/node_alerts.yml groups: - name: node_alerts rules: - alert: DiskWillFillIn4Hours expr: predict_linear(node_filesystem_free_bytes{mountpoint="/"}[1h],4*3600) < 102400000000 for: 10s labels: severity: critical annotations: summary: Disk on {{ $labels.instance }} will fill in approximately 4 hours - alert: InstanceDown expr: up{job="docker"} == 1 for: 10s labels: severity: critical annotations: summary: Host {{ $labels.instance }} of {{ $labels.job }} is up! myname: xiaoma {{ humanize $value }} [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
Prometheus警报
[root@mcw03 ~]# touch /etc/rules/prometheus_alerts.yml [root@mcw03 ~]# vim /etc/rules/prometheus_alerts.yml [root@mcw03 ~]# cat /etc/rules/prometheus_alerts.yml groups: - name: prometheus_alerts rules: - alert: PrometheusConfigReloadFailed expr: prometheus_config_last_reload_successful == 0 for: 10m labels: severity: warning annotations: description: Reloading Prometheus configuration has failed on {{ $labels.instance }} . - alert: PrometheusNotConnectedToAlertmanagers expr: prometheus_notifications_alertmanagers_discovered < 1 for: 10m labels: severity: warning annotations: description: Prometheus {{ $labels.instance }} is not connected to any Alertmanagers [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
修改配置，让重载失败，因为for是10分钟，估计得是10分钟后，还是这个状态，才会发送通知
[root@mcw03 ~]# vim /etc/prometheus.yml [root@mcw03 ~]# tail -2 /etc/prometheus.yml # action: labeldrop xxxxx [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload failed to reload config: couldn't load configuration (--config.file="/etc/prometheus.yml"): parsing YAML file /etc/prometheus.yml: yaml: line 53: did not find expected key [root@mcw03 ~]#
修改正确配置，然后修改告警规则for为10s。也就是10s钟后还是这个状态，就发送通知。然后把配置改坏，重载配置失败触发告警
[root@mcw03 ~]# vim /etc/rules/prometheus_alerts.yml [root@mcw03 ~]# grep 10 /etc/rules/prometheus_alerts.yml for: 10s for: 10m [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]# echo xxx >>/etc/prometheus.yml [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload failed to reload config: couldn't load configuration (--config.file="/etc/prometheus.yml"): parsing YAML file /etc/prometheus.yml: yaml: line 55: could not find expected ':' [root@mcw03 ~]#
之前黄色是pending，现在红色是发送了通知了把
重载失败的邮件告警出来了，只是有点延迟的厉害，邮件通知，这个邮件主题，好像是标签合在一起了
可用性警报(服务，up机器，缺失指标)
服务可用性
我们之前开启systemd，只收集三个服务的情况。
查找服务状态active不是1的，就是服务不正常的，然后告警
编写告警配置文件
[root@mcw03 ~]# vim /etc/rules/keyongxing_alerts.yml [root@mcw03 ~]# cat /etc/rules/keyongxing_alerts.yml groups: - name: keyongxing_alerts rules: - alert: NodeServiceDown expr: node_systemd_unit_state{state="active"} == 0 for: 60s labels: severity: critical annotations: summary: Service {{ $labels.name }} on {{ $labels.instance }} is nolonger active! description: Werner Heisenberg says - "OMG Where's my service?"

[root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload
没有看到这个告警规则，看到报错，先把报错去掉

[root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
可以看到，可以同名的。现在是两个，我们找的是alert的名字，而不是找组的-name名字，找错了
我们停掉这个服务，触发一下告警
停止服务

已经触发状态不等于1了
发送 告警通知。虽然告警规则，同样的规则写了两次，并且两个都是触发告警状态，但是这里只发送了一次通知，合理
服务重新启动，告警告警消失
机器可用性
求平均值
分组聚合，根据作业工作组，求每组的up的均值。
找每个job组，up均值在一半以下，也就是%50的实例无法完成抓取，就可以用来触发告警
-------
up的有7个
根据job分组求和，up的个数
分组统计up个数
=---------
缺失指标告警
情况如下，用absent，如果有这个指标，就不会返回数据。如果没有这个指标，就返回值为1.这里用于判断这个指标是否存在，表达式是否可以。检测是否存在缺失的指标
absent检测是否存在缺失的指标
[root@mcw03 ~]# cat /etc/rules/node_rules.yml groups: - name: node_rules interval: 10s rules: - record: instance:node_cpu:avg_rate5m expr: 100 - avg(irate(node_cpu_seconds_total{job='agent1',mode='idle'}[5m])) by (instance)*100 - record: instace:node_memory_usage:percentage expr: (node_memory_MemTotal_bytes-(node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes))/node_memory_MemTotal_bytes*100 labels: metric_type: aggregation name: machangwei - name: xiaoma_rules rules: - record: mcw:diskusage expr: (node_filesystem_size_bytes{mountpoint="/"}-node_filesystem_free_bytes{mountpoint="/"})/node_filesystem_size_bytes{mountpoint="/"}*100 - alert: InstanceGone expr: absent(up{job="agent1"}) for: 10s labels: severity: critical annotations: summary: Host {{ $labels.name }} is nolonger reporting! description: ‘Werner Heisenberg says - "OMG Where are my instances?" [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
修改为不存在的job，就是缺少值，然后触发了告警
修改配置之前
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '13xx2@163.com' smtp_auth_username: '13xx2@163.com' smtp_auth_password: 'ExxxxNW' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: receiver: email receivers: - name: 'email' email_configs: - to: '8xx5@qq.com' [root@mcw04 ~]#
修改之后。路由下面有分支路由，可以使用标签匹配和正则表达式匹配接受者，接受者在rceivers里面可以定义多个，路由匹配那里用的是接受者配置下的name名称来找到接收者
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '13xx32@163.com' smtp_auth_username: '13xxx32@163.com' smtp_auth_password: 'EHxxNW' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: pager - match_re: serverity: ^(warning|critical)$ receiver: support_team receivers: - name: 'email' email_configs: - to: '8xx15@qq.com' - name: 'support_team' email_configs: - to: '89xx5@qq.com' - name: 'pager' email_configs: - to: '13xx32@163.com' [root@mcw04 ~]# systemctl restart alertmanager.service [root@mcw04 ~]#
先弄的都没有触发告警的
突然发现，我这里把告警规则，写到记录规则下面了。他俩的区别是，一个是record，另外一个是alert,可以混合写在一起，在这里。
找三个，两个是criticlal的，一个是warning告警的，手动触发一下
由下可以看到，有critical标签的都发送到163邮箱了。有warning的，是发送到qq邮箱了，告警根据标签或者正则，匹配到了不同的接收者，然后发送到不同的地方了
路由表(多条件匹配)
先将上面的告警恢复
现在的配置是这个的
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '13xx32@163.com' smtp_auth_username: '13xx2@163.com' smtp_auth_password: 'ExxSRNW' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: pager - match_re: serverity: ^(warning|critical)$ receiver: support_team receivers: - name: 'email' email_configs: - to: '8xx5@qq.com' - name: 'support_team' email_configs: - to: '8xx5@qq.com' - name: 'pager' email_configs: - to: '13xx2@163.com' [root@mcw04 ~]#
critical会匹配到pager，pager是163邮箱
停止一个服务，触发带有critical标签的告警
[root@mcw02 ~]# systemctl stop rsyslog.service
[root@mcw02 ~]#
可以看到163邮箱有这个告警了
qq邮箱并没有
下面重新启动这个服务，恢复告警后，修改路由配置
首先给这个警报规则的，加个标签
[root@mcw03 ~]# cat /etc/rules/keyongxing_alerts.yml groups: - name: Keyongxing_alerts rules: - alert: NodeServiceDown expr: node_systemd_unit_state{state="active"} != 1 for: 60s labels: severity: critical service: machangweiapp annotations: summary: Service {{ $labels.name }} on {{ $labels.instance }} is nolonger active! description: Werner Heisenberg says - "OMG Where's my service?" [root@mcw03 ~]# curl -X POST http://localhost:9090/-/reload [root@mcw03 ~]#
加的是这个标签
看配置，只看路由部分的,在match下，再接一个路由匹配，这样就是如果是有标签critical的会发给163邮箱。如果再匹配到service:machangweiapp的，那么会发送到qq邮箱，多层匹配。
[root@mcw04 ~]# cat /etc/alertmanager/alertmanager.yml ..... route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: pager routes: - match: service: machangweiapp receiver: support_team - match_re: serverity: ^(warning|critical)$ receiver: support_team receivers: - name: 'email' email_configs: - to: '8x5@qq.com' - name: 'support_team' email_configs: - to: '8x15@qq.com' - name: 'pager' email_configs: - to: '13x2@163.com' [root@mcw04 ~]#
[root@mcw04 ~]# systemctl restart alertmanager.service
[root@mcw04 ~]#
下面触发告警试试
有问题，告警服务

这里应该是齐平
改成如下，route -match 两个，多了空格
route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: pager routes: - match: service: machangweiapp receiver: support_team - match_re: serverity: ^(warning|critical)$ receiver: support_team
再次重启，正常了
可以看到，已经按照预期，发送给qq了
163邮箱没有收到
continue开启之后，好像是这个匹配上之后，还可以继续往下匹配；如果是发送到多个地方，可以用这个，默认值是false。
routes: - match: severity: critical receiver: pager continue: true
接收器和通知模板
接收器
在pager接收者下面加slack_configs配置
- name: 'pager' email_configs: - to: '13x32@163.com' slack_configs: - api_url: https://hooks.slack.com/services/ABC123/ABC123/EXAMPLE channel: #monitoring text: '{{ .CommonAnnotations.summary }}'

tar -xvzf prometheus-webhook-dingtalk-2.1.0.linux-amd64.tar.gz
mv prometheus-webhook-dingtalk-2.1.0.linux-amd64 webhook_dingtalk
cd webhook_dingtalk
- 编写配置文件（复制之后切记删除#的所有注释，否则启动服务时会报错），将上述获取的钉钉webhook地址填写到如下文件
vim dingtalk.yml
timeout: 5s
targets:
webhook_robot:
# 钉钉机器人创建后的webhook地址

# 提醒全员
mention:
all: true
- 进行系统service编写
创建webhook_dingtalk配置文件
cd /usr/lib/systemd/system
vim webhook_dingtalk.service
- webhook_dingtalk.service 文件填入如下内容后保存
:wq

需要提前新增钉钉群的机器人，所以我们需要参考下面链接，申请机器人
我们下面。alertmanager配置里接收者用的是webhook1,dingtalk程序的配置里，需要配置secret,所以我们将机器人改下。
取消之前的关键字，使用加签，这个secret就是用的这个加签。

记下 urls=http://localhost:8060/dingtalk/webhook_robot/send 这一段值
http://10.0.0.14:8060/dingtalk/webhook1/send

修改之后:
修改的地方是：
路由添加了下面标签匹配到的就发往dingtalk接收者
- match:
severity: critical
receiver: dingtalk
接收者下面新增了dingtalk配置。访问地址，就是dingtalk运行的机器和端口,需要修改的地方就是指定用dingtalk下的定义的那个webhook名称，我们这里用的是webhook1
- name: 'dingtalk'
webhook_configs:
- url: http://10.0.0.14:8060/dingtalk/webhook1/send
send_resolved: true
[root@mcw04 system]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '13xx2@163.com' smtp_auth_username: '13xx2@163.com' smtp_auth_password: 'ExxNW' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: dingtalk - match: severity: critical receiver: pager #routes: #- match: # service: machangweiapp # receiver: support_team - match_re: serverity: ^(warning|critical)$ receiver: support_team receivers: - name: 'email' email_configs: - to: '8xx5@qq.com' - name: 'support_team' email_configs: - to: '8xx5@qq.com' - name: 'pager' email_configs: - to: '13xxx32@163.com' - name: 'dingtalk' webhook_configs: - url: http://10.0.0.14:8060/dingtalk/webhook1/send send_resolved: true [root@mcw04 system]# systemctl restart alertmanager.service [root@mcw04 system]#
重启一下，这个带有标签是critiacal的服务。这样就能触发告警
[root@mcw02 ~]# systemctl start rsyslog.service [root@mcw02 ~]# systemctl stop rsyslog.service [root@mcw02 ~]#
触发的是这条告警规则
这里显示，是dingtalk
我们可以看到，我们的机器人已经发送了告警信息，在钉钉群里面
邮件通知模板
5.1.1、案例需求
默认的告警信息有些太简单，我们可以借助于告警的模板信息，对告警的信息进行丰富增加。我们需要借助于alertmanager的模板功能来实现。
5.1.2、使用流程
1、分析关键信息 2、定制模板内容 3、prometheus加载模板文件 4、告警信息使用模板内容属性
5.2、定制邮件模板
5.2.1、编写邮件模板
mkdir /data/server/alertmanager/email_template && cd /data/server/alertmanager/email_template
cat >email.tmpl<<'EOF'
{{ define "test.html" }}
<table border="1">
<thead>
<th>告警级别</th>
<th>告警类型</th>
<th>故障主机</th>
<th>告警主题</th>
<th>告警详情</th>
<th>触发时间</th>
</thead>
<tbody>
{{ range $i, $alert := .Alerts }}
<tr>
<td>{{ index $alert.Labels.severity }}</td>
<td>{{ index $alert.Labels.alertname }}</td>
<td>{{ index $alert.Labels.instance }}</td>
<td>{{ index $alert.Annotations.summary }}</td>
<td>{{ index $alert.Annotations.description }}</td>
<td>{{ $alert.StartsAt }}</td>
</tr>
{{ end }}
</tbody>
</table>
{{ end }}
EOF
属性解析：
{{ define "test.html" }} 表示定义了一个 test.html 模板文件，通过该名称在配置文件中应用。
此模板文件就是使用了大量的ajax模板语言。
$alert.xxx 其实是从默认的告警信息中提取出来的重要信息。

]# vi /data/server/alertmanager/etc/alertmanager.yml
# 全局配置【配置告警邮件地址】
global:
resolve_timeout: 5m
smtp_smarthost: 'smtp.126.com:25'
smtp_from: '**ygbh@126.com'
smtp_auth_username: 'pyygbh@126.com'
smtp_auth_password: 'BXDVLEAJEH******'
smtp_hello: '126.com'
smtp_require_tls: false
# 模板配置
templates:
- '../email_template/*.tmpl'
# 路由配置
route:
group_by: ['alertname', 'cluster']
group_wait: 10s
group_interval: 10s
repeat_interval: 120s
receiver: 'email'
# 收信人员
receivers:
- name: 'email'
email_configs:
- to: '277667028@qq.com'
send_resolved: true
html: '{{ template "test.html" . }}'
headers: { Subject: "[WARN] 报警邮件" }
# 规则主动失效措施，如果不想用的话可以取消掉
inhibit_rules:
- source_match:
severity: 'critical'
target_match:
severity: 'warning'
equal: ['alertname', 'dev', 'instance']
属性解析：
{{}} 属性用于加载其它信息，所以应该使用单引号括住
{} 不需要使用单引号，否则服务启动不成功
@@@
把标签包含critical 的告警，路由到钉钉的注释掉，让它路由到pager,pager发送到163邮箱，添加下面三个配置，让它用这个我们创建的配置。我们上面是定义了
如何找到test.html。因为这个配置文件里面定义了模板的路径。那么新增这个模板是匹配到的，是可以作为模板识别出来的，里面又定义了这个模板的名称是test.html。所以发送消息的时候用这个模板渲染生成页面
5.2.3、检查语法是否正常
命令在alertmanager的tar解压包里
]# amtool check-config /data/server/alertmanager/etc/alertmanager.yml Checking '/data/server/alertmanager/etc/alertmanager.yml' SUCCESS Found: - global config - route - 1 inhibit rules - 1 receivers - 1 templates SUCCESS
[root@mcw04 template]# /tmp/alertmanager-0.26.0.linux-amd64/amtool check-config /etc/alertmanager/alertmanager.yml Checking '/etc/alertmanager/alertmanager.yml' SUCCESS Found: - global config - route - 0 inhibit rules - 4 receivers - 1 templates SUCCESS [root@mcw04 template]#
5.2.4、重启alertmanager服务
systemctl restart alertmanager
重启完之后，已经触发并发送了告警通知
可以看到告警信息
从alert变量里面获取的生成的数据，从alfert下的标签注解里面获取对应的内容
钉钉通知模板
创建模板文件
[root@mcw04 template]# cat /etc/alertmanager/template/default.tmpl {{ define "default.tmpl" }} {{- if gt (len .Alerts.Firing) 0 -}} {{- range $index, $alert := .Alerts -}} ============ = **<font color='#FF0000'>告警</font>** = ============= #红色字体 **告警名称:** {{ $alert.Labels.alertname }} **告警级别:** {{ $alert.Labels.severity }} 级 **告警状态:** {{ .Status }} **告警实例:** {{ $alert.Labels.instance }} {{ $alert.Labels.device }} **告警概要:** {{ .Annotations.summary }} **告警详情:** {{ $alert.Annotations.message }}{{ $alert.Annotations.description}} **故障时间:** {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }} ============ = end = ============= {{- end }} {{- end }} {{- if gt (len .Alerts.Resolved) 0 -}} {{- range $index, $alert := .Alerts -}} ============ = <font color='#00FF00'>恢复</font> = ============= #绿色字体 **告警实例:** {{ .Labels.instance }} **告警名称:** {{ .Labels.alertname }} **告警级别:** {{ $alert.Labels.severity }} 级 **告警状态:** {{ .Status }} **告警概要:** {{ $alert.Annotations.summary }} **告警详情:** {{ $alert.Annotations.message }}{{ $alert.Annotations.description}} **故障时间:** {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }} **恢复时间:** {{ ($alert.EndsAt.Add 28800e9).Format "2006-01-02 15:04:05" }} ============ = **end** = ============= {{- end }} {{- end }} {{- end }} [root@mcw04 template]#
新增配置指定模板，并且webhook中使用模板
[root@mcw04 template]# ps -ef|grep ding root 34609 1 0 00:26 ? 00:00:00 /prometheus/webhook_dingtalk/prometheus-webhook-dingtalk --config.file=/prometheus/webhook_dingtalk/dingtalk.yml --web.listen-address=:8060 root 34747 2038 0 00:34 pts/0 00:00:00 grep --color=auto ding [root@mcw04 template]# cat /prometheus/webhook_dingtalk/dingtalk.yml ## Request timeout # timeout: 5s ## Uncomment following line in order to write template from scratch (be careful!) #no_builtin_template: true ## Customizable templates path #templates: # - contrib/templates/legacy/template.tmpl ## You can also override default template using `default_message` ## The following example to use the 'legacy' template from v0.3.0 #default_message: # title: '{{ template "legacy.title" . }}' # text: '{{ template "legacy.content" . }}' ## Targets, previously was known as "profiles" templates: - /etc/alertmanager/template/default.tmpl targets: webhook1: url: https://oapi.dingtalk.com/robot/send?access_token=2f1532xx1a0c # secret for signature secret: SEC079xxac1e3 message: text: '{{ template "default.tmpl" . }}'
重启服务
[root@mcw04 template]# systemctl restart webhook_dingtalk.service
恢复alertmanager配置
routes: - match: severity: critical receiver: dingtalk - name: 'dingtalk' webhook_configs: - url: http://10.0.0.14:8060/dingtalk/webhook1/send send_resolved: true
完整配置如下
[root@mcw04 template]# cat /etc/alertmanager/alertmanager.yml global: smtp_smarthost: 'smtp.163.com:465' smtp_from: '135xx32@163.com' smtp_auth_username: '13xx2@163.com' smtp_auth_password: 'EHUKxxSRNW' smtp_require_tls: false templates: - '/etc/alertmanager/template/*.tmpl' route: group_by: ['instance','cluster'] group_wait: 30s group_interval: 5m repeat_interval: 3h receiver: email routes: - match: severity: critical receiver: dingtalk - match: severity: critical receiver: pager #routes: #- match: # service: machangweiapp # receiver: support_team - match_re: serverity: ^(warning|critical)$ receiver: support_team receivers: - name: 'email' email_configs: - to: '8xx5@qq.com' - name: 'support_team' email_configs: - to: '8xxx5@qq.com' - name: 'pager' email_configs: - to: '1xx2@163.com' send_resolved: true html: '{{ template "test.html" . }}' headers: { Subject: "[WARN] 报警邮件" } - name: 'dingtalk' webhook_configs: - url: http://10.0.0.14:8060/dingtalk/webhook1/send send_resolved: true [root@mcw04 template]#
停止以及开启这个服务，触发这个告警规则
[root@mcw02 ~]# systemctl start rsyslog.service [root@mcw02 ~]# systemctl stop rsyslog.service [root@mcw02 ~]#
触发的告警规则如下
告警效果如下，当产生告警时，用这个模板发送了告警，当告警恢复时，也发送了告警消息。就是消息有很大的延迟，感觉。告警消息很久才能显示在群里，恢复通知也很久才发出来，不知道是不是哪里时间设置有延迟问题还是就是这样慢
silence和维护
通过alertmanager控制silence
把匹配critical发给钉钉的注释掉，让它走下面的pager,也就是163邮箱
重启服务
[root@mcw04 template]# systemctl restart alertmanager.service
停止服务，触发下面的警报规则
[root@mcw02 ~]# systemctl stop rsyslog.service
[root@mcw02 ~]#
通知已经发送
可以看到这个，已经发送告警通知了
现在我添加silence
添加匹配标签
点击这里报错了
按enter键把它加进去
点击创建
创建成功
可以查看
可以编辑和使之过期
停止服务触发告警
[root@mcw02 ~]# systemctl stop rsyslog.service
[root@mcw02 ~]#
告警显示时间是utc时间，差了8个小时，
状态变红了e
并没有新的告警通知
并没有告警通知产生
指定过期
我们看上面过期时间是1:31，然后看我们的告警通知时间，9点31，减去时差，正好就是过期时间发送出去的。也就是添加了slice之后，Prometheus上能看到触发警报规则，但是alertmanager没有发送通知。当slice过期之后，因为服务还没恢复，告警通知立马发送出去了。
通过amtool控制silence
[root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence add alertname=InstancesGone service=machangweiapp amtool: error: comment required by config [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence add --comment "xiaoma test" alertname=InstancesGone service=machangweiapp 836bb0d7-4501-4d6a-bd0d-a03e659eec13 [root@mcw04 ~]#
可以看到新增的
不过这个匹配不到，应该这个名称的告警规则，没有带有标签service的标签。但是依然是可以创建出来sillences的
查询silence
[root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence query ID Matchers Ends At Created By Comment 836bb0d7-4501-4d6a-bd0d-a03e659eec13 alertname="InstancesGone" service="machangweiapp" 2024-02-13 03:14:26 UTC root xiaoma test [root@mcw04 ~]#
使silence失效
[root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence query ID Matchers Ends At Created By Comment 836bb0d7-4501-4d6a-bd0d-a03e659eec13 alertname="InstancesGone" service="machangweiapp" 2024-02-13 03:14:26 UTC root xiaoma test [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence expire 836bb0d7-4501-4d6a-bd0d-a03e659eec13 [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool --alertmanager.url=http://10.0.0.14:9093 silence query ID Matchers Ends At Created By Comment [root@mcw04 ~]#
添加配置文件，默认家目录下面那个文件，然后写上参数，这样命令行可以省去一些参数，
[root@mcw04 ~]# mkdir -p .config/amtool [root@mcw04 ~]# vim .config/amtool/config.yml [root@mcw04 ~]# cat .config/amtool/config.yml alertmanager.url: "http://10.0.0.14:9093" [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool silence add --comment "xiaoma test1" alertname=InstancesGone service=machangwei01 709516e6-2725-4c15-9280-8871c28dc890 [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool silence query ID Matchers Ends At Created By Comment 709516e6-2725-4c15-9280-8871c28dc890 alertname="InstancesGone" service="machangwei01" 2024-02-13 03:30:40 UTC root xiaoma test1 [root@mcw04 ~]#
指定作者，指定过期时间24小时。我们可以看到，第二条，就是第二天的结束时间了，命令行默认是当天系统用户创建
[root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool silence add --comment "xiaoma test2" alertname=InstancesGone service=machangwei02 --author "马昌伟" --duration "24h" 90ad0a5d-5fe4-4da4-996e-fc8a70a87552 [root@mcw04 ~]# /tmp/alertmanager-0.26.0.linux-amd64/amtool silence query ID Matchers Ends At Created By Comment 709516e6-2725-4c15-9280-8871c28dc890 alertname="InstancesGone" service="machangwei01" 2024-02-13 03:30:40 UTC root xiaoma test1 90ad0a5d-5fe4-4da4-996e-fc8a70a87552 alertname="InstancesGone" service="machangwei02" 2024-02-14 02:45:23 UTC 马昌伟 xiaoma test2 [root@mcw04 ~]#
