# WildFly Domain by JMX

## Overview

Official JMX Template for WildFly Domain Controller.


## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- WildFly 22.6.0 

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

Metrics are collected by JMX.
This template works with Domain Controller.

1. Enable and configure JMX access to WildFly. See documentation for [instructions](https://docs.wildfly.org/23/Admin_Guide.html#JMX).
2. Copy jboss-client.jar from `/(wildfly,EAP,Jboss,AS)/bin/client` in to directory `/usr/share/zabbix-java-gateway/lib`
3. Restart Zabbix Java gateway
4. Set the user name and password in host macros {$WILDFLY.USER} and {$WILDFLY.PASSWORD}.
Depending on your server setup, you may need to specify a custom JMX scheme in macro {$WILDFLY.JMX.PROTOCOL} (default: remote+http)


### Macros used

|Name|Description|Default|
|----|-----------|-------|
|{$WILDFLY.USER}||`zabbix`|
|{$WILDFLY.PASSWORD}||`zabbix`|
|{$WILDFLY.JMX.PROTOCOL}||`remote+http`|
|{$WILDFLY.DEPLOYMENT.MATCHES}|<p>Filter of discoverable deployments</p>|`.*`|
|{$WILDFLY.DEPLOYMENT.NOT_MATCHES}|<p>Filter to exclude discovered deployments</p>|`CHANGE_IF_NEEDED`|
|{$WILDFLY.SERVER.MATCHES}|<p>Filter of discoverable servers</p>|`.*`|
|{$WILDFLY.SERVER.NOT_MATCHES}|<p>Filter to exclude discovered servers</p>|`CHANGE_IF_NEEDED`|
