J2EE/.NET - Probes Metrics Graph

This graph displays performance metrics collected by HPE Diagnostics probes. Metrics include JVM related data such as Heap usage and Garbage Collection, application server specific metrics, JDBC (Java Database Connectivity) metrics, and more.

X-axis

Elapsed time since the scenario run.

Y-axis

Resource usage. The following probe metric data is provided for offline analysis:

  • HeapUsed

  • GC Collections/sec

  • GC time Spent in Collections

To include additional Probe metric data in offline Analysis, you use the Diagnostics configuration file, etc./offline.xml. For more information, see the HPE Diagnostics Server Installation and Administration Guide.

Data Grouping

By default, the data in the graph is grouped by Category Name (the Diagnostics metric category name) and Probe Name. As a result, the default format for the measurement name is the graph is:

<Name of metric from Diagnostics (unit of metric)>:<Diagnostics metric category name>:<Probe name>

If the measurement unit is a count, no unit name is displayed in parentheses.

Important Information

By default, the following probe metric data is provided for offline analysis: HeapUsed, GC Collections/sec, and GC time Spent in Collections. To include additional Probe metric data in offline Analysis, you use the Diagnostics configuration file, etc/offline.xml. For more information, see the HPE Diagnostics LoadRunner and Performance Center-Diagnostics Integration Guide .

For example, for the following measurement name:

  • the name of the metric is GC Time Spent in Collections.

  • the value is measured as a percentage.

  • the metric category name is GC.

  • the Probe name is MyJBossDev

In addition to the regular Analysis filter criteria, you can also filter and group by the Diagnostics metrics collector name and the host name.

Note

You need to synchronize the operating system time settings on the Controller machine and the Diagnostics Servers to ensure accurate display of the elapsed scenario time in the Probe Metrics graph.
