zabbix监控docker容器
- 第一步：
在 zabbix-agent 的安装目录下创建脚本目录：
例： ]# mkdir -p /etc/zabbix/script
在 script 目录创建脚本： docker_script.py 。 注意：需要给脚本可执行权限。
脚本内容如下：
1 #!/usr/bin/python 2 import sys 3 import os 4 import json 5 6 def discover(): 7 d = {} 8 d['data'] = [] 9 with os.popen("docker ps -a --format {{.Names}}") as pipe: 10 for line in pipe: 11 info = {} 12 info['{#CONTAINERNAME}'] = line.replace("\n","") 13 d['data'].append(info) 14 print(json.dumps(d)) 15 16 17 def status(name,action): 18 if action == "ping": 19 cmd = 'docker inspect --format="{{.State.Running}}" %s' %name 20 result = os.popen(cmd).read().replace("\n","") 21 if result == "true": 22 print(1) 23 else: 24 print(0) 25 else: 26 cmd = 'docker stats %s --no-stream --format "{{.%s}}"' % (name,action) 27 result = os.popen(cmd).read().replace("\n","") 28 if "%" in result: 29 print(float(result.replace("%",""))) 30 else: 31 print(result) 32 33 34 if __name__ == '__main__': 35 try: 36 name, action = sys.argv[1], sys.argv[2] 37 status(name,action) 38 except IndexError: 39 discover()
- 第二步：
修改 zabbix-agent 配置文件 /etc/zabbix/zabbix_agentd.conf
1 UnsafeUserParameters=1 2 3 UserParameter=docker_script.discovery,/usr/local/zabbix/script/docker_script.py 4 5 UserParameter=docker_script.[*],/usr/local/zabbix/script/docker_script.py $1 $2
注意：改完配置后，需要重启zabbix-agent ：systenctl restart zabbix-agent
- 第三步：
在 zabbix-server 端验证获取agent数据是否正常：（需要安装zabbix-get 插件）
- 第四步：
在 zabbix-server端导入模板：
