Zabbix监控Docker容器配置

#zabbix #Docker

三，监控Docker容器

用python脚本监控容器状态 vi docker_status.py

#!/usr/bin/env python

import sys
import os
import json


def discover():
	d = {}
	d['data'] = []
	with os.popen("docker ps -a --format {{.Names}}") as pipe:
		for line in pipe:
			info = {}
			info['{#CONTAINERNAME}'] = line.replace("\n","")
			d['data'].append(info)

	print json.dumps(d)


def status(name,action):
	if action == "ping":
		cmd = 'docker inspect --format="{{.State.Running}}" %s' %name
		result = os.popen(cmd).read().replace("\n","")
		if result == "true":
			print 1
		else:
			print 0
	else:
		cmd = 'docker stats %s --no-stream --format "{{.%s}}"' % (name,action)
		result = os.popen(cmd).read().replace("\n","")
		if "%" in result:
			print float(result.replace("%",""))
		else:
			print result


if __name__ == '__main__':
		try:
				name, action = sys.argv[1], sys.argv[2]
				status(name,action)
		except IndexError:
				discover()

vi docker_status.conf

UserParameter=docker_status[*],sudo python /etc/zabbix/zabbix_agentd.d/docker_status.py $1 $2
