Performance Monitoring Infrastructure settings

Use this page to specify settings for performance monitoring, including enabling performance monitoring, selecting the Performance Monitoring Infrastructure (PMI) module and setting monitoring levels.

To view this administrative console page, click Servers > Application Servers > server > Performance Monitoring Infrastructure (PMI).

Configuration tab

Enable Performance Monitoring Infrastructure (PMI)

Whether the application server attempts to enable Performance Monitoring Infrastructure (PMI). If an application server is started when the PMI is disabled, you have to restart the server in order to enable it.

Use sequential counter updates

Whether access to PMI counters (for example, updates to the counters) is sequential. There is some performance overhead associated with enabling sequential update. The default setting is false.

Currently monitored statistic set

Specifies a pre-defined set of Performance Monitoring Infrastructure (PMI) statistics for all components in the server. As part of fine-grained control feature, WebSphere Application Server provides new statistic sets, which are pre-defined, fixed server-side sets based on the PMI statistic usage scenarios. This enhancement allows a set of statistics to be enabled via a single action or call. The following statistic sets are defined:

None

All statistics are disabled.

Basic

Provides basic monitoring for application server resources and applications. This includes J2EE components, HTTP session information, CPU usage information, and the top 38 statistics. This is the default setting.

Extended

Provides extended monitoring, including the basic level of monitoring plus workload monitor, performance advisor, and Tivoli resource models. Extended provides key statistics from frequently used WebSphere Application Server components.

All

Enables all statistics.

Custom

Provides fine-grained control with the ability to enable and disable individual statistics.

Runtime tab

Use sequential counter updates

Whether access to PMI counters (for example, updates to the counters) is sequential. There is some performance overhead associated with enabling sequential update. The default setting is false.

Persist my changes

Whether changes to the runtime are also persisted for use on subsequent server startups, and not just the current server runtime. The default setting is false.

Selecting the Persist my changes option ensures that the counter settings are retained after you restart the server. This option itself does not remain selected the next time you come to the panel.
