zabbix配置自定义监控

目录

zabbix配置自定义监控项---进程监控

环境说明

服务端 192.168.32.136
客户端 192.169.32.125

服务端和客户端一配置完成，参考文档：

zabbix监控服务部署
zabbix配置客户端

1. 编写获取进程状态的脚本

 
[root@client ~]# mkdir /scripts
[root@client ~]# cd /scripts/
[root@client scripts]# vim check_process.sh
#!/bin/bash
process_status=$(ps -ef | grep $1 | grep -Ev "$0|grep" |wc -l)
if [ $process_status -eq 0 ];then
    echo '1'
else
    echo '0'
fi

//进程存在就输出0，进程不存在就输出1


[root@client scripts]# ls
check_process.sh
[root@client scripts]# chmod +x check_process.sh

2. 修改配置文件，添加自定义key

[root@client scripts]# vim /usr/local/etc/zabbix_agentd.conf
......
# UnsafeUserParameters=0
 UnsafeUserParameters=1		//0改为1

### Option: UserParameter
#       User-defined parameter to monitor. There can be several user-defined parameters.
#       Format: UserParameter=<key>,<shell command>
#       See 'zabbix_agentd' directory for examples.
#
# Mandatory: no
# Default:
# UserParameter=
UserParameter=check_process[*],/bin/bash /scripts/check_process.sh $1
//改完之后重启zabbix_agentd

3. 配置监控项

4. 添加触发器


5. 媒介和动作

媒介和动作使用之前脚本的方式


6. 触发并验证

//客户端关闭服务
[root@client etc]# systemctl stop postfix

zabbix配置自定义监控项---日志监控

1. 客户端编写获取进程状态的脚本

[root@client ~]# vim /scripts/log.py
#!/usr/bin/env python3
import sys
import re

def prePos(seekfile):
    global curpos
    try:
        cf = open(seekfile)
    except IOError:
        curpos = 0
        return curpos
    except FileNotFoundError:
        curpos = 0
        return curpos
    else:
        try:
            curpos = int(cf.readline().strip())
        except ValueError:
            curpos = 0
            cf.close()
            return curpos
        cf.close()
    return curpos

def lastPos(filename):
    with open(filename) as lfile:
        if lfile.readline():
            lfile.seek(0,2)
        else:
            return 0
        lastPos = lfile.tell()
    return lastPos

def getSeekFile():
    try:
        seekfile = sys.argv[2]
    except IndexError:
        seekfile = '/tmp/logseek'
    return seekfile

def getKey():
    try:
        tagKey = str(sys.argv[3])
    except IndexError:
        tagKey = 'Error'
    return tagKey

def getResult(filename,seekfile,tagkey):
    destPos = prePos(seekfile)
    curPos = lastPos(filename)

    if curPos < destPos:
        curpos = 0

    try:
        f = open(filename)
    except IOError:
        print('Could not open file: %s' % filename)
    except FileNotFoundError:
        print('Could not open file: %s' % filename)
    else:
        f.seek(destPos)

        while curPos != 0 and f.tell() < curPos:
            rresult = f.readline().strip()
            global result
            if re.search(tagkey, rresult):
                result = 1
                break
            else:
                result = 0

        with open(seekfile,'w') as sf:
            sf.write(str(curPos))
    finally:
        f.close()
    return result

if __name__ == "__main__":
    result = 0
    curpos = 0
    tagkey = getKey()
    seekfile = getSeekFile()
    result = getResult(sys.argv[1],seekfile,tagkey)
    print(result)

2. 在客户端编辑配置文件

[root@client ~]# vim /usr/local/etc/zabbix_agentd.conf
......
UnsafeUserParameters=1
......
UserParameter=check_log[*],/usr/bin/python /scripts/log.py $1 $2 $3
#第一个参数为日志文件名（必须有，相对路径、绝对路径均可）
#第二个参数为seek position文件的路径（可选项，若不设置则默认为/tmp/logseek文件。相对路径、绝对路径均可）
#第三个参数为搜索关键字，默认为 Error

#配置完成之后重启服务
#让zabbix对/var/log/secure有读权限
[root@client ~]# setfacl -m u:zabbix:r /var/log/secure

3. 配置监控项和触发器



已经配置了邮箱告警，这里直接触发

[root@localhost ~]# 
[root@localhost ~]# ssh root@192.168.32.125
root@192.168.32.125's password: 
Permission denied, please try again.
