Zabbix监控-mingodb数据库状态

最近公司数据库新增加了几台mongodb数据库，为了能实时了解运行的状态，需要增加zabbix对mongodb的运行状态监控。
mongodb默认安装情况下可以运行echo "db.serverStatus()" | mongo 来获取mongodb的运行状态，但是公司数据库安装的时候修改了默认的连接端口，这样一来运行这个命令就报错了
[root@localhost ~]# echo "db.serverStatus()" | mongo
MongoDB shell version: 2.x.x
connecting to: test
Wed Jun 4 14:39:37 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed
默认的27017端口显示连接不上，这就需要我们在mongo后面加上服务器地址及端口号比如
[root@localhost ~]# echo "db.serverStatus()" | mongo 10.0.0.12:40000

因此可以考虑使用zabbix的UserParameter自定义监控，对MongoDB进行监控

添加MongoDB监控

1、zabbix客户端配置文件zabbix_agentd.conf文件，添加如下内容：

UserParameter=MongoDB.Status[*],/bin/echo "db.serverStatus().$1" | /usr/local/sbin/mongo 10.0.0.12:40000 | grep "$2"|awk -F: '{print $$2}'|awk -F, '{print $$1}'

2、重新启动zabbix客户端

/etc/init.d/zabbix_agentd restart

3添加MongoDB监控模板
导入模板
选择configuration-template 右上角import，导入模板“zbx_mongodb-monitor_templates.xml”，稍后会放在文章的最下面附件中供大家下载
