Zabbix监控qemuKVM进程-low_level_discovery

时间:2017-06-04 10:42:58   收藏:0   阅读:1784

  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:

1 #!/usr/bin/env python
2 import os
3 import json
4 t=os.popen("""ps -e -o ‘pid,comm,pcpu,rsz,vsz,stime,user,uid,cmd‘ |awk ‘$7=="qemu" {print $11}‘""")
5 kvms = []
6 for kvm in  t.readlines():
7     virshName = os.path.basename(kvm.strip())
8     kvms += [{{#QEMU}:virshName}]
9 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}‘`
;;
memory_usage)
query_result=`cat ${psfile} | grep $2 | awk ‘{print $3}‘`
;;
sz_usage)
query_result=`cat ${psfile} | grep $2 | awk ‘{print $4}‘`
;;
rsz_usage)
query_result=`cat ${psfile} | grep $2 | awk ‘{print $5}‘`
;;
vsz_usage)
query_result=`cat ${psfile} | grep $2 | awk ‘{print $6}‘`
;;
*)
echo ERROR
exit 1;
esac
rm -rf ${psfile}
echo ${query_result}
