The bucket Parameter

The bucket parameter is common to all SAFs. 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". The bucket statistics are displayed by the perfdump utility, which can be set up through the Admin Console, CLI, or through the service-dump SAF. For more information, see service-dump.

The following performance buckets are predefined:

• The default-bucket records statistics for the functions not associated with any user-defined or built-in bucket.

• The all-requests bucket records perfdump statistics for all NSAPI SAFs, including those in the default-bucket.
