Using the Facility
You must remember that all transactions for a process are considered to
fail the service level agreement if either the first-response or the
response-to-prompt time exceeds the specified values. If you want to use
only one criterion--such as response-to-prompt time--you should set the
other criterion (in this case, first-response) to a large value. For
example, to use a response-to-prompt service level of 1 second, set
RESPONSE=1 and FIRST=3000.
Set the values by adding the following line after the desired APPLICATION
line in the PARM file:
SERVICE [LEVEL] FIRST=seconds RESPONSE=seconds
If service levels are not set for an application, it will use the
interesting process threshold values for FIRST and RESPONSE. If only one
service level threshold is set, the other will not be used.
By default, processes that violate a service level agreement are
considered interesting and will be logged even if they are not
interesting for any other reason. The Interest Reason for these
processes will be set to FIRST or PROMPT depending on which thresholds
were violated.
Recommendations
1. If only one application is included in the agreement, specify the
SERVICE LEVEL FIRST= and RESPONSE= for that application.
2. If all or a majority of the applications are included in the
agreement, specify high interesting process thresholds
values--such as THRESHOLD RESPONSE=3000 FIRST=3000--then set the
service level thresholds for each application. In this way,
processes will be considered interesting for FIRST or PROMPT only
if they violate the corresponding service level.
3. If you want all applications on the system to have the same
service level,--for instance, if the agreement specified all users
of the system rather than specific applications--set the
interesting process thresholds to the desired values. You need
not set individual application levels.
