zabbix自动发现监控redis多实例

计算每秒命中率,这里脚本获取到底是当前命中率,模板中可调试
这里的命中率需要命中才会计算才会有值

[root@c7-test scripts]# cat redis_hits.sh

awk 'BEGIN{c=$c;a=$a;print '$a/$c*100'}'
#awk '{a[NR]=$2;b[NR]=$1;s+=$1}END{for (j=1;j<=NR;j++) printf "%s %.2f%\n",a[j],b[j]*100/s}'

这里是自动发现端口

import os
import json
t=os.popen("""ps -ef|grep redis-server|grep -v grep|awk -F'(:| )+' '{print $13}' """)
ports = []
for port in  t.readlines():
        r = os.path.basename(port.strip())
        ports += [{'{#REDISPORT}':r}]
print json.dumps({'data':ports},sort_keys=True,indent=4,separators=(',',':'))

UserParameter设置:

UserParameter=redis_port,/etc/zabbix/scripts/redis-port.py
UserParameter=redis_info[*],/usr/bin/redis-cli -h 127.0.0.1 -p $1 info |awk -F':'  '/$2\>/{print $$2}'
UserParameter=redis_hits[*],/etc/zabbix/scripts/redis_hits.sh $1 $2
