    	 (default "/tmp/supervisor.sock")

~# go-zabbix-supervisord [-sock=/var/run/supervisor.sock] discovery
{
    "data":[
        {"{#PROCESS.NAME}":"001","{#PROCESS.GROUP}":"XXX","{#PROCESS.PID}":52390},
        {"{#PROCESS.NAME}":"321","{#PROCESS.GROUP}":"XX1","{#PROCESS.PID}":52398},
        {"{#PROCESS.NAME}":"123","{#PROCESS.GROUP}":"XX2","{#PROCESS.PID}":52411},
    ]
}

~# go-zabbix-supervisord [-sock=/var/run/supervisor.sock] state.name XX2:123
RUNNING

Installation

1. Before you should check go version on your host. Just type command:

   ~# go version
   go version go1.13.5 linux/amd64

   NOTE: If golang doesnt installed on the host, you can go to official golang
   site and install it.

2. You need to check two environment variables that they are set correctly.

   ~# echo $GOROOT; echo $GOBIN
   /usr/local/go
   /usr/local/go/bin

3. supervisord must be running. Type command:

   ~# service supervisor status
   ● supervisor.service - Supervisor process control system for UNIX
      Loaded: loaded (/lib/systemd/system/supervisor.service; enabled; vendor preset: enabled)
      Active: active (running) since Wed 2019-12-04 14:05:31 MSK; 5 days ago
      ...

4. Now you can install go-zabbix-supervisord.

   ~# go get -u github.com/cardinalit/go-zabbix-supervisord

   After installing the dependencies, the executable will be installed in $GOBIN path.
   The executable will be called go-zabbix-supervisord. You can check it:

   ~# go-zabbix-supervisord help [-h | --help]
   Usage of go-zabbix-supervisord:
     -sock string
       	The full path to the socket
       	 (default "/tmp/supervisor.sock")

5. You should create (or copy from my repository) sudoers.d exception file for
   zabbix user, containing the following text:

   zabbix ALL=(ALL) NOPASSWD:/usr/local/go/bin/go-zabbix-supervisord
   Defaults:zabbix !requiretty
   

   For copy, just type:

   ~# cp ~/go/src/github.com/cardinalit/go-zabbix-supervisord/zabbix \
      /etc/sudoers.d/

6. Import zbx_export_template.xml to you Zabbix server.

7. Create (or copy from my repository) file userparameter_supervisord.conf
   to Zabbix agent path on the host. For copy, just type:

   ~# cp ~/go/src/github.com/cardinalit/go-zabbix-supervisord/userparameter_supervisord.conf \
      /etc/zabbix/zabbix_agentd.d/

8. Restart your Zabbix agent on the host.
