zabbix通过简单shell命令监控elasticsearch集群状态

简单命令监控elasticsearch集群状态

原理:
使用curl命令模拟访问任意一个es节点可以反馈的集群状态,集群的状态需要为green
curl -sXGET http://serverip:9200/_cluster/health/?pretty

{
  "cluster_name" : "yunva-es",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 7,
  "number_of_data_nodes" : 6,
  "active_primary_shards" : 66,
  "active_shards" : 132,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

前端使用了nginx验证,需要模拟登陆
curl模拟用户登录命令格式:
curl -u username:password -sXGET http://serverip:9200/_cluster/health/?pretty | grep "status"|awk -F '[ "]+' '{print $4}'

1.修改客户端zabbix配置:
vim /etc/zabbix/zabbix_agentd.conf

UserParameter=es_status,curl -u elkadmin:elkpass -sXGET http://serverip/_cluster/health/?pretty | grep "status"|awk -F '[ "]+' '{print $4}'|grep -c 'green'

重启zabbix-agent使配置生效
service zabbix-agent restart

在zabbix-server端测试
zabbix_get -s ip -p 10050 -k es_status

2.在zabbix的web页面添加对应的监控:

添加监控项item

Confuguration --> Hosts --> 找到对应的主机,点开 Items --> Create item



创建触发器:
Name
es_status_check
es_cluster_status is not green

3.针对es集群中的每个节点做进程监控,如果进程挂了自动重启

配置监控进程item


配置触发器


配置action,看参考 

zabbix系列(九)zabbix3.0实现自动触发zabbix-agent端shell脚本任务

http://blog.csdn.net/reblue520/article/details/52315154


触发脚本:

/usr/local/zabbix-agent/scripts/start_es.sh

#!/bin/bash
# if elasticsearch exists kill it
source /etc/profile
count_es=`ps -ef|grep elasticsearch|grep -v grep|wc -l`
if [ $count_es -gt 1 ];then
    ps -ef|grep elasticsearch|grep -v grep|/bin/kill `awk '{print $2}'`
fi
# start it

su yunva -c "cd /data/elasticsearch-5.0.1/bin && /bin/bash elasticsearch &"


执行:
sudo /bin/bash /usr/local/zabbix-agent/scripts/start_es.sh
报错:
which: no java in (/sbin:/bin:/usr/sbin:/usr/bin)
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME

解决办法:
在脚本中添加
source /etc/profile

以root用户运行elasticsearch

报错:
can not run elasticsearch as root

网上的方法,针对elasticsearch5.1不起作用
解决方法1:
在执行elasticSearch时加上参数-Des.insecure.allow.root=true,完整命令如下

./elasticsearch -Des.insecure.allow.root=true  
解决办法2:
用vi打开elasicsearch执行文件,在变量ES_JAVA_OPTS使用前添加以下命令

ES_JAVA_OPTS="-Des.insecure.allow.root=true"  

解决办法:
su yunva -c "cd /data/elasticsearch-5.0.1/bin && /bin/bash elasticsearch &"

自动拉起kibana服务的脚本:
cat /usr/local/zabbix/scripts/restart_kibana.sh
#!/bin/bash
# if kibana exists kill it

count_kibana=`ps -ef|grep kibana|grep -v grep|wc -l`
if [ $count_kibana -eq 1 ];then
    ps -ef|grep kibana|grep -v grep|/bin/kill `awk '{print $2}'`
fi

# start it


排错思路:

针对每台es的节点进行检查,发现有无法访问的,问题就出在这里了

# curl http://10.27.1.10:9200/
curl: (56) Recv failure: Connection reset by peer
