一、编写自动发现脚本
[root@test-db zabbix_agentd.d]# cat /etc/zabbix/monitor_sh/redis_discovery.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import re
import json
import os
CONF_DIR = '/data/redis/conf'
pattern = re.compile(r'redis\S+.conf')
def filterlist():
#获取dir列表
conf_list = os.listdir(CONF_DIR)
new_filet_list = []
for i in conf_list:
data = {}
if os.path.isfile(os.path.join(CONF_DIR,i)) and pattern.search(i):
with open(os.path.join(CONF_DIR,i),'r') as f:
for line in f:
bind_ip = re.findall(r'^bind\s+(\d+\.\d+\.\d+\.\d+)',line)
bind_port = re.findall(r'^port\s+(.*)', line)
bind_pass = re.findall(r'^requirepass\s+(.*)', line)
if bind_ip:
ip = ''.join(bind_ip)
if ip == '0.0.0.0':
ip = '127.0.0.1'
data['{#IP}'] = ip
if bind_port:
data['{#PORT}'] = ''.join(bind_port)
if bind_pass:
#print bind_pass
str_pass = ''.join(bind_pass)
#print str_pass
password = str_pass.strip('"')
#print password
data['{#PASSWORD}'] = password
#print password
#print 'data:',data
#else:
# password = 'null'
# data['{#PASSWORD}'] = password
new_filet_list.append(data)
#print 'data',data
return json.dumps({'data':new_filet_list},sort_keys=True,indent=4,separators=(',',':'))
if __name__ == "__main__":
result = filterlist()
print result
二、编写redis监控脚本
[root@test-db zabbix_agentd.d]# cat /etc/zabbix/monitor_sh/redis.sh
#!/bin/bash
# Redis状态及info信息监控脚本
# Author yousong.xiang 250919938@qq.com
# Date 2019.03.13,2020.11.12
# v1.0.2
# 添加百分比监控(现redis服务做成自动发现目标，之前通过模板取值方式不兼容)
[ -f /etc/profile ] && . /etc/profile
REDIS="redis-cli"
if [ # -ne 4 ]; then
echo "input error"
exit 9
fi
HOST=1
PORT=2
PASS=3
CURRENT=4
#以下为兼容redis无密码状态，传参值为null则赋值为''
if [ "{PASS}" == "" ]; then
PASS=
fi
function RedisPing() {
RESULT=`{REDIS} -h{HOST} -p {PORT} -a "{PASS}" ping |grep -c PONG `
if [ {RESULT} -ne 1 ]; then
ping_result=1
echoping_result
exit 7
else
ping_result=0
echo ping_result
fi
}
function RedisStatus() {
REDIS_CLI="{REDIS} -h {HOST} -p{PORT} -a "{PASS}" info"
result=`{REDIS_CLI}|grep -w {CURRENT}| awk -F':' '{print2}'`
echo {result}
}
function used_memory_human() {
code=`RedisPing`
result=`RedisStatus`
# 以下分别写入三种条件判断，因为结果唯一，可以这么写，之后再优化
M_CODE=`echo{result}|grep -i m |wc -l`
G_CODE=`echo {result}|grep -i g |wc -l`
K_CODE=`echo{result}|grep -i k |wc -l`
if [ "{M_CODE}" == "1" ]; then
code=`echo{result}|awk -F '.' '{print 1}'`
fi
if [ "{G_CODE}" == "1" ]; then
code=`echo {result}|awk -F 'G' '{print1}'`
code=`echo "{code}*1024"|bc`
fi
if [ "{K_CODE}" == "1" ]; then
code='1'
fi
echo {code%.*}
}
function maxmemory_human() {
code=`RedisPing`
result=`RedisStatus`
# 以下分别写入三种条件判断，因为结果唯一，可以这么写，之后再优化
M_CODE=`echo{result}|grep -i m |wc -l`
G_CODE=`echo {result}|grep -i g |wc -l`
K_CODE=`echo{result}|grep -i k |wc -l`
if [ "{M_CODE}" == "1" ]; then
code=`echo{result}|awk -F '.' '{print 1}'`
fi
if [ "{G_CODE}" == "1" ]; then
code=`echo {result}|awk -F 'G' '{print1}'`
code=`echo "{code}*1024"|bc`
fi
if [ "{K_CODE}" == "1" ]; then
code='1'
fi
echo {code%.*}
}

三、zabbix-agent配置文件
[root@test-db zabbix_agentd.d]# cat ../zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=30
HostMetadataItem=system.uname
Server=192.168.0.42
ServerActive=192.168.0.42
Include=/etc/zabbix/zabbix_agentd.d/*.conf
Hostname=192.168.0.146
UnsafeUserParameters=1
四、后台添加模板
4.1监控项原型
4.2触发器原型
4.3图形原型
五、查看图形信息
