One, prepare one zabbix server, one monitored machine, and install zabbix_agentd and docker services on the monitored machine.
The ip of my docker machine here is 192.168.4.10, and the hostname is docker. (The zabbix version I installed is 3.4.4, docker version: docker-ce 18.06.1)
Second, modify the configuration in zabbix_agentd.conf on the docker machine as follows:
# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=docker.discovery,/usr/local/zabbix/script/docker.py
UserParameter=docker.[*],/usr/local/zabbix/script/docker.py $1 $2
Third, write the following code into /usr/local/zabbix/script/docker.py, and add permissions to the script
# vim /usr/local/zabbix/script/docker.py
# chmod 777 /usr/local/zabbix/script/docker.py
#!/usr/bin/python
import sys
import os
import json
def discover():
d = {}
d['data'] = []
with os.popen("sudo 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 = 'sudo docker inspect --format="{
{.State.Running}}" %s' %name
result = os.popen(cmd).read().replace("\n","")
if result == "true":
print 1
else:
print 0
else:
cmd = 'sudo 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()Fourth, execute the command visudo to add the following content:
zabbix ALL=(ALL) NOPASSWD:/usr/bin/docker
# python /usr/local/zabbix/script/docker.py Test whether the script can be executed normally. Normally, you should be able to get the container in docker, and the result is in json format.
After configuring the above, you can restart zabbix_agentd first
Test whether the key can be executed successfully through the zabbix_get command
# zabbix_get -s 127.0.0.1 -k 'docker.[nginx,CPUPerc]'
At this point, the zabbix_agent terminal is ready, and then add templates and monitoring items on the zabbix management page.
Five, page configuration
First add the corresponding docker host
Create a new template
Add app set
Add auto-discovery rules
Add new item prototype
Add cpu and mem two monitoring prototypes
Link the docker host to the new template
After a while, you should be able to see the monitored data in the latest data.
