Enabling/disabling agent plugin using REST or remote API

Solution Verified - Updated

Environment

  • Red Hat JBoss Operations Network (ON) 3.3
  • Red Hat JBoss ON REST API 3.3
  • Red Hat JBoss ON Command Line Interface (CLI) 3.3

Issue

  • Enabling/disabling agent plugin using REST or remote API
  • I am looking for a rest call or a cli which helps me enabling and disabling the plugin on specific Agent.

Resolution

There is no way to disable/enable agent plugin using JBoss ON This content is not included.REST API.

As of JBoss Operations Network 3.3 Update 11, the Remote API supports the This content is not included.PluginManager.disablePlugins(List pluginIds) and This content is not included.PluginManager.enablePlugins(List pluginIds) methods.

Root Cause

According to the JBoss ON This content is not included.Remote API it should be possible to use PluginManager to disable/enable plugins. However, attempt to use one of the methods disablePlugin, enablePlugin or deletePlugin fails with the message: 

org.jboss.remoting.CannotConnectException: Can not connect http client invoker after 1 attempt(s)

This was due to in incorrect class mapping used by the CLI.

This issue was captured in This content is not included.Red Hat Bugzilla 1522728.
