上篇最后提到了jstat，jstat可以查看统计JVM内存信息，那么结合Zabbix，就可以监控多实例的JVM内存了。
1、下面两个脚本部署在被监控主机：
vm.py
用于JVM实例PID查找，ps命令亦可以换成jdk自带的jps工具：
#!/usr/bin.python
#
import os
import json
data = {}
tcp_list = []
port_list = []
command = "ps -ef | grep weblogic.Server | grep -v "grep web" | awk '{print $2}'"
lines = os.popen(command).readlines()
for line in lines:
port=line.strip('
')
# port = line.split(':')[1]
port_list.append(port)
for port in list(set(port_list)):
port_dict = {}
port_dict['{#PID}'] = port
tcp_list.append(port_dict)
data['data'] = tcp_list
jsonStr = json.dumps(data, sort_keys=True, indent=4)
print jsonStr
getvm.sh
统计内存使用情况脚本，需修改JAVA_HOME环境变量：
#!/bin/bash
#
JAVA_HOME="/u01/Middleware/jdk1.6.0_45"
javapid=$2
#S0
function s0 {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $1}')
}
#S1
function s1 {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $2}')
}
#Eden
function eden {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $3}')
}
#Old
function old {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $4}')
}
#Perm
function perm {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $5}')
}
#YGC
function ygc {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $6}')
}
#YGCT
function ygct {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $7}')
}
#FGC
function fgc {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $8}')
}
#FGCT
function fgct {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $9}')
}
#GCT
function gct {
echo $(sudo -u weblogic ${JAVA_HOME}/bin/jstat -gccause $javapid | awk '{if(NR!=1) print $10}')
}
$1
exit $?
2、增加被监控主机zabbix_agentd配置文件
/etc/zabbix/zabbix_agentd.d下添加配置文件，jvm.conf
根据脚本实际目录配置：
UserParameter=java.pid,/home/weblogic/zabbix/vm.py
UserParameter=java.memory[*],/home/weblogic/zabbix/getvm.sh $1 $2
3、 为zabbix运行脚本授权
zabbix ALL=(user) NOPASSWD: /u01/Middleware/jdk1.6.0_45/bin/jstat,/usr/bin/python
Defaults !requiretty
4、 zabbix server端测试
./zabbix_get -s 192.168.1.109 -p 10050 -k 'java.pid'
{
"data": [
{
"{#PID}": "8817"
},
{
"{#PID}": "9041"
},
{
"{#PID}": "3929"
},
{
"{#PID}": "8620"
}
]
}
./zabbix_get -s 192.168.1.109 -p 10050 -k 'java.memory[old,8817]'
5.83
5、zabbix导入模板（在最后），监控即可，如果要自己配置自动发现，参考前面文章Zabbix添加自定义监控项（一）
xml模板：
<?xml version="1.0" encoding="UTF-8"?> <zabbix_export> <version>3.2</version> <date>2017-06-13T05:25:25Z</date> <groups> <group> <name>Templates</name> </group> </groups> <templates> <template>
