zabbix 5.2.6 监控进程

nginx wiki jira zabbix jumpserver 重启需要电话通知我们？
nginx 磁盘90%阈值需要电话通知我们？

解刨：进程重启需要电话通知给我们

关键点：如何才能知道进程重启了(可以通过获取进程的运行时间)

ps -p 进程pid -o etimes

system.run[ps -p $(sudo netstat -lntup|grep 10051|grep -v "tcp6"|awk '{print $NF}'|awk -F/ '{print $1}') -o etimes|tail -1|xargs echo]

# 10051 是进程的端口号

零零一：创建好的监控项如下图

 零零二：附上模板，直接导入即可(把端口修改成对应进程的端口号)
