This section tells you about different performance statistics in WebSphere® ESB.
You can monitor up to 28 performance statistics in WebSphere ESB. Three of these statistics are applicable to all server events, and the remaining 25 apply to the Service Component Architecture (SCA) level. The SCA is the layer where your applications are actually processed, which differs from WebSphere ESB events that are handled by the Common Event Infrastructure. The SCA-specific statistics are calculated from service invocations of an application, which may be comprised of one or more service components. You can use the SCA-specific statistics to assess a variety of performance measurements of the processing of your applications.
All performance measurements are either counters (a cumulative number of the firings of a given event point), or timers (the duration, measured in milliseconds, between the firings of two event points).
