zabbix使用python脚本监控java进程

分类： 系统运维

2018-02-01 18:46:35

作者：撸大师

前言：目前有个需求，需要对线上几台拥有5个tomcat的服务器添加监控，分别监控各个tomcat的gc、连接数、使用内存等，现成的模板是监控一台tomcat，完全不适用目前情况，5个tomcat，如果现在新建模板，那每个tomcat得添加十几个item,也就是要添加60多个 Ttem，而且还要添加 Trigger 和 Graph，也都是成倍的添加，如果这台服务器在增加tomcat，又得再加一次，做工重复且繁琐，于是想到能不能自动发现tomca的端口以及把不同tomcat的监控数据直接发给zabbx-server。

此文章多方百度和多次实验失败后完成的。

参考1：zabbix_sender提交item数据

参考2：zabbix自动发现并监控主机的TCP监听端口

一、发现端口和pid

 

说明：发现端口是为了区分程序；而发现pid则是便于用jstat获取程序的状态数据；
直接上脚本：

  282. </zabbix_export>

注：模板太长，我只取2个item 放置其中；

下面附上几张配置截图











目前只配置了item，还没有添加报警和图形


三、创建数据，并用zabbix_sender发送到zabbix-server

zabbix_agentd配置文件

点击(此处)折叠或打开

  1. > cat /usr/local/zabbix/etc/zabbix_agentd.conf.d/jstat.conf
  2. UserParameter=jmxport,sudo /usr/bin/python /usr/local/zabbix/scripts/jstat.py --jvmport
  3. UserParameter=jmxdata,sudo /usr/bin/python /usr/local/zabbix/scripts/jstat.py --data

执行脚本

点击(此处)折叠或打开

  1. > sudo python jstat.py --data
  2. /usr/local/zabbix/bin/zabbix_sender -c /usr/local/zabbix/etc/zabbix_agentd.conf -i /usr/local/zabbix/scripts/.zabbix_jmx_status
  3. info from server: "processed: 45; failed: 0; total: 45; seconds spent: 0.000531"
  4. sent: 45; skipped: 0; total: 45

看上面结果，成功发送45个数据，数据会先临时存到 /usr/local/zabbix/scripts/.zabbix_jmx_status，我们查看下数据内容


点击(此处)折叠或打开

  1. > cat /usr/local/zabbix/scripts/.zabbix_jmx_status
  2. test-01 jstat[8083,Young.Gc.Time] 36.572
  3. test-01 jstat[8083,Old.Gc.Time] 3.971
  4. test-01 jstat[8083,Perm.Gc.New] 80384.0
  5. test-01 jstat[8083,Total.Gc.Time] 40.543
  6. ...
  7. test-01 jstat[7074,Old.Gc.Time] 1.734
  8. test-01 jstat[7074,Perm.Gc.New] 55296.0
  9. test-01 jstat[7074,Total.Gc.Time] 26.635

第一列表示主机名，这个与zabbix_agentd.conf的配置保持一致，而且 zabbix-web添加的主机名也要一样；
第二列表示 key，这个和 templates里定义的一致；
第三列是 数据；

四、查看数据




可以看到数据已经在zabbix展示了，之后我们可以添加相应的 报警和图形，使这个 template更加完善。

#############################################
zabbix_sender发送信息两种方式
1.zabbix_get主动去获取item时会提示timeout，可以修改server，agentd的conf文件里的timeout参数为300，然后重启服务
2.通过crontd定时执行脚本

博主试过监控tomcat的数据库连接池数据吗？
