Zabbix3.4通过shell脚本监控redis服务
公司最近网站改版，增加了redis服务器，现领导要求需要测试redis的监控，于是从网上找了个redis的监控脚本，简单的修改了一下，测试中没出现任何问题。生产环境中，可根据实际要监控的参数值修改脚本内容，并添加相应的触发器。
Redis有自带的redis-cli客户端，通过info命令可以查询到redis的运行情况，我们可以写个shell脚本，通过zabbix来调用这个脚本实现redis的监控。
一、info命令的使用
要获得redis的当前情况，可以使用info命令。
命令格式：
redis-cli -h [hostname] -p [port] -a [password] info [参数]1、查询server信息
redis-cli -h 127.0.0.1 -p 6379 -a 'password' info server
2、查询客户端连接情况
redis-cli -h 127.0.0.1 -p 6379 -a 'password' info clients
3、查询内存使用情况
redis-cli -h 127.0.0.1 -p 6379 -a 'password' info memory
4、查询CPU使用情况
redis-cli -h 127.0.0.1 -p 6379 -a 'password' info cpu
二、创建redis监控脚本
1、编写监控脚本vim /etc/zabbix/zabbix_agentd.d/redis_status.sh
#!/bin/bash
REDISCLI="/usr/local/bin/redis-cli"
HOST="127.0.0.1"
PORT=6379
PASS="password"
if [[ $# == 1 ]];then
case $1 in
version)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info server | grep -w "redis_version" | awk -F':' '{print $2}'`
echo $result
;;
uptime)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info server | grep -w "uptime_in_seconds" | awk -F':' '{print $2}'`
echo $result
;;
connected_clients)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info clients | grep -w "connected_clients" | awk -F':' '{print $2}'`
echo $result
;;
blocked_clients)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info clients | grep -w "blocked_clients" | awk -F':' '{print $2}'`
echo $result
;;
used_memory)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info memory | grep -w "used_memory" | awk -F':' '{print $2}'`
echo $result
;;
used_memory_rss)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info memory | grep -w "used_memory_rss" | awk -F':' '{print $2}'`
echo $result
;;
used_memory_peak)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info memory | grep -w "used_memory_peak" | awk -F':' '{print $2}'`
echo $result
;;
used_memory_lua)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info memory | grep -w "used_memory_lua" | awk -F':' '{print $2}'`
echo $result
;;
used_cpu_sys)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info cpu | grep -w "used_cpu_sys" | awk -F':' '{print $2}'`
echo $result
;;
used_cpu_user)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info cpu | grep -w "used_cpu_user" | awk -F':' '{print $2}'`
echo $result
;;
used_cpu_sys_children)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info cpu | grep -w "used_cpu_sys_children" | awk -F':' '{print $2}'`
echo $result
;;
used_cpu_user_children)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info cpu | grep -w "used_cpu_user_children" | awk -F':' '{print $2}'`
echo $result
;;
rdb_last_bgsave_status)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info Persistence | grep -w "rdb_last_bgsave_status" | awk -F':' '{print $2}' | grep -c ok`
echo $result
;;
aof_last_bgrewrite_status)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info Persistence | grep -w "aof_last_bgrewrite_status" | awk -F':' '{print $2}' | grep -c ok`
echo $result
;;
aof_last_write_status)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info Persistence | grep -w "aof_last_write_status" | awk -F':' '{print $2}' | grep -c ok`
echo $result
;;
*)
echo -e "\033[33mUsage: $0 {connected_clients|blocked_clients|used_memory|used_memory_rss|used_memory_peak|used_memory_lua|used_cpu_sys|used_cpu_user|used_cpu_sys_children|used_cpu_user_children|rdb_last_bgsave_status|aof_last_bgrewrite_status|aof_last_write_status}\033[0m"
;;
esac
elif [[ $# == 2 ]];then
case $2 in
keys)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info | grep -w "$1" | grep -w "keys" | awk -F'=|,' '{print $2}'`
echo $result
;;
expires)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info | grep -w "$1" | grep -w "keys" | awk -F'=|,' '{print $4}'`
echo $result
;;
avg_ttl)
result=`$REDISCLI -h $HOST -a $PASS -p $PORT info | grep -w "$1" | grep -w "avg_ttl" | awk -F'=|,' '{print $6}'`
echo $result
;;
*)
echo -e "\033[33mUsage: $0 {db0 keys|db0 expires|db0 avg_ttl}\033[0m"
;;
esac
fi2、赋予脚本可执行权限
chmod +x /etc/zabbix/zabbix_agentd.d/redis_status.sh3、脚本测试
查看redis的客户端连接数
/etc/zabbix/zabbix_agentd.d/redis_status.sh connected_clients
三、创建redis监控配置文件
1、编写redis监控配置文件vim /etc/zabbix/zabbix_agentd.d/redis.conf
UserParameter=Redis.Status,status=`/usr/local/bin/redis-cli -h 127.0.0.1 -a 'password' -p 6379 ping|grep -c PONG` &&echo $status
UserParameter=Redis.Info[*],/etc/zabbix/zabbix_agentd.d/redis_status.sh $1 $22、重启zabbix-agent
systemctl restart zabbix-agent3、在zabbix server端测试
zabbix_get -s 192.168.2.235 -p 10050 -k "Redis.Info[used_cpu_user]"
四、创建并导入监控模板
1、创建监控模板文件
redis-template.xml文件内容如下
