This article mainly shows you "how zabbix monitors the status of docker containers". The content is simple and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how zabbix monitors the status of docker containers".

Preferred, zabbix_agentd configuration vim / usr/local/zabbix/etc/zabbix_agentd.conf

UserParameter=docker.discovery,/usr/local/zabbix/script/docker.pyUserParameter=docker. [*] / usr/local/zabbix/script/docker.py $1 $2

Here is the docker.py script, which uses the auto-discovery rule to discover the container, and then specifies the container to get status information

#! / usr/bin/pythonimport sysimport osimport jsondef 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 resultif _ _ name__ = ='_ main__': try: name,action = sys.argv [1], sys.argv [2] status (name,action) except IndexError: discover ()

Here's a little bit about the pit where rules are automatically discovered. It took me a long time to find out. First, the content must be returned in json format, and the other is that the key info ['{# CONTAINERNAME}'] must write {# CONTAINERNAME}.

The returned result is as follows, which must be such a hierarchical relationship.

{"data": [{# CONTAINERNAME} ":" node-3 "}, {" {# CONTAINERNAME} ":" node-2 "}, {" {# CONTAINERNAME} ":" node-1 "}, {" {# CONTAINERNAME} ":" web "}, {" {# CONTAINERNAME} ":" cadvisor "}, {" {# CONTAINERNAME} ":" updatol "}, {" {# CONTAINERNAME} ":" research "}, {" {# CONTAINERNAME} ":" services "}) {"{# CONTAINERNAME}": "data"}, {"{# CONTAINERNAME}": "rabbitmq"}, {"{# CONTAINERNAME}": "redis"}, {"{# CONTAINERNAME}": "mysql"}, {"{# CONTAINERNAME}": "ssdb"}]}

The other function is very simple, which is to call the docker command to get the data.

What about the automatic discovery rule? that's it.

Only these states are monitored, and another trigger is ping to detect whether the current container state is running or not, and alarm if not.

The template is as follows

2018-06-04T04:12:36Z Templates docker-status docker-status Templates docker_test docker.discovery 0 docker.discovery 6000 000 0 0 {# CONTAINERNAME} @ CONTAINERNAME 8 A 30 Container {# CONTAINERNAME} Diskio usage: 0 0 docker.

Modify the Zabbix_agentd configuration, put the docker.py script under the specified path, don't forget to give the permission, import the template, there is no problem to get the data. If you can't get it, you can zabbix_get to debug it and find out what the problem is.
