Zabbix自定义监控配置流程

自定义监控配置流程

自定义监控配置步骤：
1.创建脚本存放目录，写脚本，给执行权限，改脚本存放目录的属主为zabbix
2.改客户端配置文件agentd.conf

• UnsafeUserParameters=1
• UserParameter=<key_name[*]>,<shell command $1>

3.重启zabbix_agent
4.在服务端手动测试

• zabbix_get -s 客户端IP -k key_name

5.配置网页界面，添加监控项以及触发器
6.验证

注意：自定义监控要在客户端配置

1. 自定义监控进程

这里以httpd为例：

# 在客户端安装httpd
[root@agentd ~]# yum -y install httpd
[root@agentd ~]# systemctl start httpd

# 在客户端创建脚本存放目录
[root@agentd ~]# mkdir /scripts

# 写脚本
[root@agentd ~]# cat /scripts/check_process.sh 
#!/bin/bash

process=$(ps -ef|grep -Ev "grep|$0"|grep -c $1)
if [ $process -gt 0 ];then
    echo "0"
else
    echo "1"
fi

# 给脚本执行权限
[root@agentd ~]# chmod a+x /scripts/check_process.sh 
[root@agentd ~]# ll /scripts/check_process.sh
-rwxr-xr-x 1 zabbix zabbix 135 8月  24 15:26 /scripts/check_process.sh

# 改脚本存放目录的属主
[root@agentd ~]# chown -R zabbix.zabbix /scripts/
[root@agentd ~]# ll -d /scripts/
drwxr-xr-x 2 zabbix zabbix 30 8月  24 16:34 /scripts/

# 改客户端配置文件agentd.conf
[root@agentd ~]# echo "UnsafeUserParameters=1" >>/usr/local/etc/zabbix_agentd.conf
[root@agentd scripts]# echo 'UserParameter=check_process[*],/bin/bash /scripts/check_process.sh $1' >>/usr/local/etc/zabbix_agentd.conf

# 重启zabbix_agent
[root@agentd ~]# pkill zabbix_agentd
[root@agentd ~]# zabbix_agentd 

# 在服务端手动测试
[root@zabbix ~]# zabbix_get -s 192.168.100.96 -k check_process[httpd]
0  	 # 0代表没有问题
# 停掉httpd服务再测试
[root@agentd ~]# systemctl stop httpd
[root@zabbix ~]# zabbix_get -s 192.168.100.96 -k check_process[httpd]
1	 # 1代表服务没有进程运行

配置网页界面
添加监控项

• 配置——主机——监控项
• 配置以下配置其他保持默认
  

添加触发器
配置——主机——触发器

触发验证

[root@agentd ~]# systemctl restart httpd
[root@agentd ~]# systemctl stop httpd

2.自定义监控日志

这里以监控var/log/httpd/error_log为例
1.创建脚本存放目录，写脚本，给执行权限，改脚本存放目录的属主属组为zabbix

[root@96 ~]# mkdir /scripts
[root@96 ~]# cd /scripts/
[root@96 scripts]# vim 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)

[root@96 scripts]# chmod +x log.py
[root@96 scripts]# chown -R zabbix.zabbix .

2.改客户端配置文件agentd.conf

[root@96 ~]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=check_log[*],/usr/bin/python /scripts/log.py $1 $2 $3

3.重启zabbix_agent

[root@96 ~]# pkill zabbix
[root@96 ~]# zabbix_agentd

4.在服务端手动测试

[root@zabbix ~]# zabbix_get -s 192.168.100.96 -k check_log[/var/log/httpd/error_log,/tmp/qq.seek,erroe]
0

5.配置网页界面，添加监控项以及触发器


6.客户端触发验证

[root@96 ~]# echo "error" >>/var/log/httpd/error_log 
[root@96 ~]# echo "error" >>/var/log/httpd/error_log 

3.自定义监控mysql主从延迟

1.创建脚本存放目录，写脚本，给执行权限，改脚本存放目录的属主属组为zabbix

[root@96 ~]# mkdir /scripts
[root@96 ~]# vim /scripts/mysql_delay.sh
#!/bin/bash

num=$(mysql -uroot -pscl666 -e 'show slave status \G;' 2>/dev/null |grep Behind |awk '{print $NF}')
if [ $num -ne 0 ];then
    echo "1"
else
    echo "0"
fi

[root@96 ~]# chmod +x /scripts/mysql_delay.sh
[root@96 ~]# chown -R zabbix.zabbix /scripts
[root@96 ~]# chmod 750 /scripts/mysql_delay.sh    #里面有密码不给其他人权限
[root@96 ~]# ll /scripts/
-rwxr-x--- 1 zabbix zabbix 383 8月  25 16:44 mysql_delay.sh

2.改客户端配置文件agentd.conf

[root@96 ~]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=check_mysql_delay,/bin/bash /scripts/mysql_delay.sh

3.重启zabbix_agent

[root@96 ~]# pkill zabbix
[root@96 ~]# zabbix_agentd

4.在服务端手动测试

[root@zabbix ~]# zabbix_get -s 192.168.100.96 -k check_mysql_delay
0

5.配置网页界面，添加监控项以及触发器

4. 自定义配置监控mysql主从状态

1.创建脚本存放目录，写脚本，给执行权限，改脚本存放目录的属主属组为zabbix

[root@96 ~]# mkdri /scripts
[root@96 scripts]# vim mysql_state.sh
#!/bin/bash
zhuangtai=$(mysql -uroot -pscl666 -e 'show slave status \G;' 2>/dev/null |grep -E 'Slave_IO_Running:|Slave_SQL_Running:' |awk '{print $NF}' |grep Yes|wc -l)
if [ $zhuangtai -ne 2 ];then
    echo "1"
else
    echo "0"
fi



[root@96 scripts]# chmod +x mysql_state.sh
[root@96 scripts]# chown -R zabbix.zabbix .
[root@96 scripts]# chmod 750 mysql_state.sh

2.改客户端配置文件agentd.conf

[root@96 ~]# vim /usr/local/etc/zabbix_agentd.conf		#末行添加
UnsafeUserParameters=1
UserParameter=check_mysql_state,/bin/bash /scripts/mysql_state.sh

3.重启zabbix_agent

[root@96 ~]# pkill zabbix
[root@96 ~]# zabbix_agentd

4.在服务端手动测试

[root@zabbix ~]# zabbix_get -s 192.168.100.96 -k check_mysql_state
0

5.配置网页界面，添加监控项以及触发器
