18.4.5.1. 创建 Mongo 监控用户

创建监控用户

				
[root@netkiller www.netkiller.cn]# mongo -u admin -p D90YVqwmUATUeFSxfRo14  admin

> use admin
switched to db admin

> db.createUser(
   {
     user: "monitor",
     pwd: "chen",
     roles: [ "clusterMonitor"]
   }
)

Successfully added user: { "user" : "monitor", "roles" : [ "clusterMonitor" ] }

> db.auth("monitor", "netkiller")
1

> exit

18.4.5.3. Zabbix server 测试

				
[root@netkiller ~]# zabbix_get -s www.netkiller.cn -k mongodb.status[ok]
1
[root@netkiller ~]# zabbix_get -s www.netkiller.cn -k mongodb.status[version]
2.6.12
				
				

测试成功后导入模板

监控内容如下

链接数监控(当前连接数和可用连接数)
mongodb current mongodb.status[connections,current] 
mongodb available mongodb.status[connections,available] 

流量监控(每秒请求数,出站流量,入站流量)
mongodb mongodb.status[network,numRequests]
mongodb mongodb.status[network,bytesOut]
mongodb mongodb.status[network,bytesIn]

命令统计(查询，更新，插入，删除......)
mongodb query/s mongodb.status[opcounters,query]
mongodb update/s mongodb.status[opcounters,update]
mongodb insert/s mongodb.status[opcounters,insert]
mongodb getmore/s mongodb.status[opcounters,getmore]
mongodb delete/s mongodb.status[opcounters,delete]
mongodb command/s mongodb.status[opcounters,command]

内存监控
mongodb mem virtual mongodb.status[mem,virtual]
mongodb mem resident mongodb.status[mem,resident]
mongodb mem mapped mongodb.status[mem,mapped]
mongodb mem mappedWithJournal mongodb.status[mem,mappedWithJournal]

复制监控

 
mongodb repl mongodb.status[repl,ismaster]

锁监控
# zabbix_get -s www.chuangfu24.net -k mongodb.status[locks,admin,timeAcquiringMicros,r]
