Performance hints

The Health Center agent has little effect on performance. You can improve the performance of the Health Center agent in several ways.

Monitored Application: Reducing the amount of data collected

You can further minimize the agent resource usage by reducing the amount of data collected. The Health Center provides a low resource usage mode which can be enabled by adding the option level=low to the Health Center command line. For example:
-agentlib:healthcenter=level=low -Xtrace:output=perfmon.out
or
-Xhealthcenter:level=low

Health Center Client: Reducing the amount of data collected

Collecting less data also reduces the memory footprint of the Health Center client. For related information about collecting less data, see Controlling the amount of data generated.

Health Center Client: Reducing the amount of data displayed

The Health Center stores a configurable amount of historical data. Storing less historical data reduces the memory footprint of the Health Center and improves performance. To configure the age at which data is discarded and how often the Health Center deletes old data, modify the data storage settings as described in Saving data.
