Performance monitoring for mediations

This topic describes the performance information that can be monitored for mediations.

Mediation performance monitoring is provided by Performance Monitoring Infrastructure (PMI); the core monitoring infrastructure for WebSphere Application Server.

When PMI is enabled, two pieces of statistical information are updated continuously for each mediated destination, as described in the following table:

Performance statistic Description
Mediation Time The time taken to perform the mediation.
Messages Mediated A count of the number of messages mediated at this destination.

Mediated destination level statistics can be aggregated by mediation. An additional statistic is updated on request for each mediation, as described in the following table:

Performance statistic Description
Thread Allocated The number of threads in the mediation thread pool performing work for the mediation.
Mediation level statistics can be aggregated by messaging engine, and messaging engine level statistics can be aggregated to provide statistics for the application server.
