The following performance buckets are predefined in Sun Java System Web Server:
The default-bucket records statistics for the functions not associated with any user-defined or built-in bucket.
The all-requests bucket records.perf statistics for all NSAPI SAFs, including those in the default-bucket.
You can define additional performance buckets in the magnus.conf file (see the perf-init and define-perf-bucket functions).
You can measure the performance of any SAF in obj.conf by adding a bucket=bucket-name parameter to the function, for example bucket=cache-bucket.
To list the performance statistics, use the service-dump Service function.
As an alternative, you can use the stats-xml Service function to generate performance statistics; use of buckets is optional.
For more information about performance buckets, see the Sun Java System Web Server 6.1 SP11 Performance Tuning, Sizing, and Scaling Guide.
