zabbix監控雲端mysql等實例。
傳統的mysql 服務器 用zabbix很容易實現，單對於雲端的mysql 實例 我想你們都是用的雲自帶的監控。咱們前端時間aws 雲端mysql 實現主從 進程的出現問題，然而aws 自帶的監控沒有。前端
咱們就想到 zabbix 實現對aws mysql 實例的監控。mysql
1監控的服務遠程去鏈接 awsmysql 取監控的數值就很容易實現了。redis
建立用戶sql
GRANT USAGE,PROCESS,REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO zabbixtest@'10.%' IDENTIFIED BY 'zabbixtest';bash
2.監控客戶端 zabbix配置文件的服務器
serParameter=mysqlstatustest[*],/data/scripts/zabbix/mysql_check.sh "$1 $2 $3 $4"ide
3監控腳本重寫。這個就是比較麻煩的事情 在這裏我貢獻給你們，我用的是zabbix3.2 版本實現的。memcached

mysql 須要鏈接的數據的 用戶 和密碼還有 ip 就須要在模版裏面寫宏變量實現。優化
4模版的添加 rate 有幾個key 我沒寫。server
模版在附件 zabbix 3.0才能使用此模版
若是須要redis和memcache 模版 和遠程監控實現方法 請聯繫我。
5注意事項
因爲 因此的 mysql 實例的監控都是從這一臺zabbix－agentd 取的數值
因此這臺監控的機器 的壓力很大
StartPollersUnreachable=10 server 須要優化這個參數
客戶端的配置文件 須要優化超時時間和buffer 大小
6tip
腳本優化方向，能夠寫個crontab 把狀態數據 存到臨時文件裏面 ，而後腳本 取這個文件裏面的數值，這樣鏈接數能下降不少，由於時間倉促 因此腳本沒優化。
咱們的 這一臺監控 mysql redis memcached 實例 都是用的這個方式，並且都是這個機器取的 50個實例的數值 （1核2gb的監控 客戶端）同時仍是一個zabbix－proxy。
