prometheus配置ping监测
vim prometheus.yml中添加如下内容
- job_name: "主机网络监测"
metrics_path: /probe
params:
module: [ping]
file_sd_configs:
- refresh_interval: 10s
files:
- "/usr/local/prometheus/ping_host/ping_status*.yml"
relabel_configs:
- source_labels: [__address__]
regex: (.*)(:80)?
target_label: __param_target
replacement: ${1}
- source_labels: [__param_target]
target_label: instance
- source_labels: [__param_target]
regex: (.*)
target_label: ping
replacement: ${1}
- source_labels: []
regex: .*
target_label: __address__
replacement: 127.0.0.1:9115 #此处是black_exporter和prometgeus关联的地方
创建ping_status.yml文件
[root@codeversionforgitserver ping_host]# more ping_status.yml

[root@codeversionforgitserver ping_host]#
此时prometheus配置ping监测完成;
检查是否成功
访问prometheus
点击会出一个链接地址,访问此地址(注意&需要转义)通过配置文件可以很直接的看出Prometheus使用black_exporter作为代理使用black_exporter配置的module检测各个target的状态
[root@codeversionforgitserver ping_host]# curl http://codeversionforgitserver:9115/probe?module=ping\&target=10.1.32.142
