Monitoring production uPortal instances is key to catching problems early and ensuring smooth operation. Memory usage, garbage collection, CPU usage, and resource pools are all important metrics when determining the health of a portal instance.

Monitoring Methods

Monitoring memory can be achieved several ways as detailed on the Monitoring uPortal memory at runtime page.
With the advent of JMX in Java 5 most important information can be obtained through this single method remotely and in an efficient manner.

Monitoring Tools

jConsole Provides a web-based UI and gathers information from multiple machines using JMX.
UW Dashboard A web-based dashboard for monitoring a group of servers using metrics gathered via JMX.
