This blog describes the alert configuration process on JBOSS Operations Network. It is expected that the reader has sufficient knowledge of Linux Operating system and JON is installed on his machine.

* Operating System: CentOS 6.5 (64-bit)

* Product: JBOSS Operations Network 3.2

For your own testing and installation please visit http://rhq-project.github.io/rhq/. RHQ is an upstream project of JBOSS ON written mostly in JAVA.

JON offers two types of alerts

1. Alert Definition Templates

2. Individual Resource Alerts

1. Alert Definition Templates

The alerts defined in this category are applied to whole group. See following example

2. Individual Resource Alerts

The individual resource alerts can be setup on number of conditions, like CPU, Memory or Disk space usage. The individual alerts can be defined by following Inventory–>Platform–>Alerts–>Definition
