zabbix 監控redis sentinel

經過externalscripts監控redis sentinel的狀態,可是隻支持監控一個redis集羣的sentinel，由於只監控master0，要支持多集羣的sentinel的話本身寫個返回各個master0-xxx的json格式的腳本，配合自動探索去作吧。

externalscripts 腳本

#cat check_sentinel.sh #放在externalscripts路徑下，zabbix用戶可執行

#!/bin/bash

ip=$1
port=$2
check=$3

#(echo -en "INFO\r\n";sleep 1)|nc $ip $port 

if [ $check == "uptime" ] || [ $check == "redisclustername" ] || [ $check == "redisclusterstatus" ] || [ $check == "slavenum" ] || [ $check == "sentinelnum" ] || [ $check == "redismaster" ] 
then
case $check in 
uptime)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^uptime_in_seconds:|awk -F: '{print $2}'
;;
redisclustername)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^master0:name|sed 's/^.*:name=//'|sed 's/,status=.*$//'
;;
redisclusterstatus)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^master0:name|sed 's/^.*,status=//'|sed 's/,address=.*$//'
;;
slavenum)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^master0:name|sed 's/^.*slaves=//'|sed 's/,sentinels=.*$//'
;;
sentinelnum)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^master0:name|sed 's/^.*sentinels=//'
;;
redismaster)
(echo -en "INFO\r\n";sleep 1)|nc $ip $port |grep ^master0:name|sed 's/^.*,address=//'|sed 's/,slaves.*$//'
;;

else
echo "not support $3."&&exit 1
