HP Integrated Archive Platform Performance Graphs and Counters Whitepaper

The following system level counters are collecting performance data from each server in a host group:

• Idle CPU – Percentage of time the processor is not active. For example, if the CPU counter

averages 70% idle, then we can conclude the CPU was busy processing tasks 30% of the

time.

• Free Memory – The Free Memory counter is a percentage of total system memory utilized

• JVM Heap Total – Amount of memory reported in bytes JVM has allocated for Java

Objects

• JVM Heap Used – Amount of memory reported in bytes JVM is using to store active Java

Objects

• JVM Virtual Memory Used – Amount of virtual memory reported in bytes the JVM

processes are using

• IO – Percentage of total disk utilization

• Active Thread Count – Number of Java threads that JBoss is running

A graph for each counter can be generated by selecting the desired counter from the Select Graph

Type drop-down menu in the System Monitoring (CPU, MEM – Thresholds) tab.
