centos环境下使用zabbix配合python脚本对supervisor中的进程运行状态进行监控

# 需要监控的supervisor相关的进程如下
# supervisorctl status

# shell脚本结合zabbix自动发现对supervisor监控

1.脚本
# vim /usr/local/zabbix_agents_3.2.0/scripts/zbx_discovery_supervisor.sh

#!/bin/bash
# For auto discovery of supervisor
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# list all processes
PROCESSES=`sudo /usr/bin/supervisorctl -c  /usr/local/supervisor/supervisord.conf  status 2>/dev/null| grep -v 'supervisor.sock'|awk '{print $1}'`


# get processes array
INDEX=0
for PROCESS_NAME in $PROCESSES
do
    PROCESS_NAME_NUM[$INDEX]=$PROCESS_NAME
    let INDEX=INDEX+1
done

num=$(echo ${#PROCESS_NAME_NUM[@]})
# echo json
printf '{\n'
printf '\t"data":[\n'
for((i=0;i<${#PROCESS_NAME_NUM[@]};++i))
{
    NUM=$(echo $((${#PROCESS_NAME_NUM[@]}-1)))
        if [ "$i" != ${NUM} ];then
            printf "\t\t{ \n"
            printf "\t\t\t\"{#PROCESS_NAME}\":\"${PROCESS_NAME_NUM[$i]}\"},\n"
        else
            printf  "\t\t{ \n"
            printf  "\t\t\t\"{#PROCESS_NAME}\":\"${PROCESS_NAME_NUM[$NUM]}\"}\n"
        fi
}
printf ']}'

2.监控项
vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/supervisor_agentd.conf

UserParameter=supervisor.discovery,/bin/bash /usr/local/zabbix_agents_3.2.0/scripts/zbx_discovery_supervisor.sh
UserParameter=supervisor.status[*],sudo /usr/bin/supervisorctl -c  /usr/local/supervisor/supervisord.conf status $1 2>/dev/null| awk '{print $$2}'

3.添加具体的监控
