HPA Portal sections Common HPA portal components Infrastructure

This block gives information on the JVM infrastructure metrics :

  • CPU
  • Memory
  • Garbage collection
  • Network bandwith

For each one of these infrastructure metrics, the displayed value corresponds to the highest plateau reached on the monitored period. Information about the dates when this plateau was reached is provided bellow each metric name.

In details :

  1. CPU : the raw data are based on standard Broadcom APM CPU metric It is the percentage of the total computing power of the host, but limited to the percentage utilized by the monitored JVM.

  2. Memory : based on standard Broadcom Memory metrics, it records the memory usage (byte in use and byte total).

  3. Garbage Collection (GC) : based on standard Broadcom Memory metrics, it records the percentage of time spent in GC during the last 15 minutes. If JVM stays in garbage collection, it can not handle its requests. It is often a sizing or usage anomaly when the GC value is too high.

  4. Network bandwith : based on standard Broadcom Network metrics, This is the number of Bytes per seconds recorded on the sockets used in the program. In HPA portal, this is the highest plateau for the sum of all sockets bandwith which is displayed. In a word, the maximum bandwith use by the JVM process.

On all these metrics, HPA portal display is the highest plateau for the selected period. It analyzes the graph for each metrics and computes the maximum usage.
