JBoss Servers

Introduction:

This section is common to all the editions of IT360, as per the below constraints;

Supported Versions:

IT360 supports monitoring of JBoss Servers of versions 3.2.x, 4.x, 4.0.1, 4.0.2 & above, and 5.0.0 & above. Performance data is collected by deploying an agent, automatically from IT360 to the JBoss server that needs to be monitored.

Monitored Parameters:

JBoss servers are monitored, based on the attributes such as JVM heap Usage, Response time, etc. and the different web applications and EJB, deployed in the server. The monitoring details of JBoss server are represented graphically, which helps to understand the parameters, with ease. You can also configure thresholds to the attributes, monitored by the server, based on these details. 

Availability tab, gives the Availability history for the past 24 hours or 30 days. Performance tab gives the Health Status and events for the past 24 hours or 30 days. List view enables you to perform Bulk admin configurations. Click on the individual monitors listed, to view the following information.
