Zabbix self-discovery monitors the status of various services in docker containers and containers in Real Time Online Business display

This article consists of three parts:
1. view your environment variables and service paths
(1) JDK environment: jdk1.8

(2) zabbix version: zabbix3.4.5
(3) zabbix script storage path:/data/zabbix/scripts/
(4) path to the. conf file:/data/zabbix/etc/zabbix_agentd.conf.d/

2. Configure scripts, keys, and templates
First, configure Vim/data/zabbix/etc/zabbix_agentd.conf.d/docker. conf in zabbix_agentd.

Userparameter = docker. Discovery,/data/zabbix/scripts/docker. py
Userparameter = docker. [*],/data/zabbix/script/docker. py $1 $2

The following is the docker. py script, which uses the automatic discovery rule to discover the container, and then specifies the container to obtain the status information:

#! /Usr/bin/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

IfName='Main':
Try:
Name, Action = SYS. argv [1], SYS. argv [2]
Status (name, Action)
Failed t indexerror:
Discover ()

Here we will discuss how to automatically discover the pitfalls of rules... It took me a long time to find out ..... first, JSON format content must be returned, and second, info ['{# containername}'] The key must be written in this way {# containername}
The returned result is as follows:

{"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"}]}

In addition, the function is very simple, that is, the docker command is called to obtain data.

Then import the template:
The template is as follows:

After the template is imported
Some people may encounter this problem after importing the template:
Zabbixglobal regular expression "container name" does not exist.

This problem proves that the problem is not serious.
Remove this from this location.

If you want to know what this means, please refer to the official website: zabbix Regular Expression writing, the general meaning is as follows:

To manage, general, click regular inside

You just need to know how to use this and add it.
Next, let's take a look at what is monitored in the template.

Trigger has

Check the latest data.

We can see that the status of each container has been added,
By now, you can turn to your leadership.
