zabbix自定义监控
自定义监控进程
测试监控httpd，需要在监控端部署httpd，以方便监控
配置监控脚本
#在监控端
[root@localhost ~]# dnf -y install httpd
[root@localhost ~]# systemctl start httpd
[root@localhost ~]# ss -anlt | grep 80
LISTEN 0 128 *:80 *:*
#编写脚本
[root@localhost ~]# mkdir /scripts
[root@localhost ~]# vim /scripts/check_process.sh
#!/bin/bash
count=$(ps -ef|grep -Ev "grep|$0" | grep $1 | wc -l)
if [ $count -eq 0 ];then
echo '1'
else
echo '0'
fi
[root@localhost ~]# chmod +x /scripts/check_process.sh
[root@localhost ~]# ll /scripts/check_process.sh
-rwxr-xr-x. 1 root root 119 Sep 6 21:09 /scripts/check_process.sh
#在监控端，修改配置文件
[root@localhost ~]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UnsafeUserParameters=check_process[*],/bin/bash /scripts/check_process.sh $1
#服务端检查key是否可用
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[httpd]
0
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[mysql]
1
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[zabbix]
0
添加监控项
查看监控数据
添加触发器
手动关闭httpd，进行测试触发报警
[root@localhost ~]# systemctl stop httpd
查看报错
发送邮件
查看邮件
自定义监控日志
初学者复制的脚本
忘情的log脚本日志
#由于是python的脚本，需要在python环境中
[root@localhost ~]# dnf -y install python36
#编写脚本
[root@localhost ~]# cd /etc/scripts/
[root@localhost scripts]# vim log.py
#!/usr/bin/env python3

return curpos
except FileNotFoundError:

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]

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)
