Zabbix监控qemuKVM进程-low_level_discovery
本文介绍基于Zabbix LLD（low_level_discovery）自动发现机制创建自动发现脚本及对详细进程进行监控。执行过程：
1：基于py脚本寻找KVM主机上的虚拟机名称，返回JSON格式
2：配置Zabbix模板，自动生成监控列表信息
3：基于ps命令获取监控值
代码文件：
获取虚拟机名称列表：
#!/usr/bin/env python
import os
import json
t=os.popen("""ps -e -o 'pid,comm,pcpu,rsz,vsz,stime,user,uid,cmd' |awk '$7=="qemu" {print $11}'""")
kvms = []
for kvm int.readlines():
virshName = os.path.basename(kvm.strip())
kvms += [{'{#QEMU}':virshName}]
print json.dumps({'data':kvms},sort_keys=True,indent=4,separators=(',',':'))
获取监控详情：
#!/bin/bash
psfile=/tmp/$$.$$
ps -e -o 'pid,pcpu,pmem,sz,rsz,vsz,user,cmd' | awk '
BEGIN {
printf "%s\t%s\t%s\t%s\t%s\t%s\t%s\n","pid","pcpu","pmem","sz","rsz","vsz","user","CMD"
}
$7=="qemu" {
printf "%s\t%s\t%s\t%.2f\t%.2f\t%.2f\t%s\t%s\n",$1,$2,$3,$4*1024,$5*1024,$6*1024,$7,$10
}
' > ${psfile}
PIDD=`cat ${psfile} | grep $2 | awk '{print $1}'`
#PIDD=$(ps -ef | grep $2 | grep -v grep| awk '{print $2}')
case $1 in
CPU_usage)
query_result=`/usr/bin/top -b -p $PIDD -n 1 | awk '/qemu/ {print $9}'`
;;

query_result=`cat ${psfile} | grep $2 | awk '{print $3}'`

query_result=`cat ${psfile} | grep $2 | awk '{print $5}'`
;;

query_result=`cat ${psfile} | grep $2 | awk '{print $6}'`
;;
*)
echo ERROR
exit 1;
esac
rm -rf ${psfile}
echo ${query_result}
