To monitor whether a group of Processes runs too long,
construct an SLC duration schedule and reference that schedule in
a workflow SLC group.
About this task
The workflow SLC group contains appropriate values for server
groups, servers, and other SLC match criteria. The match criteria
specifies the Process, Processes, Process step, or Process steps you
are interested in. For example, say that PROCESSA runs on SERVERA,
PROCESSB runs on SERVERB, and PROCESSC runs on SERVERC, and that all
must run within 10 minutes.
Procedure
- Since you are interested in knowing that multiple related
Processes run within a specified amount of time, use a workflow SLC.
Associate a duration SLC schedule with it.
For this example,
the duration SLC schedule has the following attributes:
| Name |
Schedule Type |
Enabled |
Minimum Duration |
Maximum Duration |
| Duration |
Duration Schedule |
Yes |
000:00:00 |
000:10:00 |
- The workflow SLC that references this duration SLC schedule
is defined as follows:
| Name |
Enabled |
Generate notification if event has not occurred |
Monitor Window Tolerances Start |
Monitor Window Tolerances End |
| Watch for Processes A, B, and C |
Yes |
Yes |
6 |
6 |
Monitor Window Tolerances: Start and End specify when you
want an SLC to begin and end monitoring. In this instance, because
a duration SLC schedule is being associated with the workflow SLC,
Start Monitor Window Tolerance is immaterial. The reason is that we
do not care what time the Processes begin, only that they all run
within a specified duration.
The End Monitor Window Tolerance
tells IBM® Sterling Control Center
Monitor how long to continue watching for the end of the
workflow beyond the schedule associated with the workflow SLC. You
might make the value for both the Start and End Monitor Window Tolerances
as short as zero hours.
- Specify the duration SLC schedule previously defined. The
schedule specifies a minimum duration of 0 seconds and a maximum duration
of 10 minutes.
- On the Parameters pane, the value
you select for Milestone Times Relative To, Actual Start or Scheduled
Start, only matters if NSR and NER or both values are specified for
the SLCs milestones.
Concurrence Count is set to 1 because
we expect only one occurrence of this workflow to be executing within
the monitoring window specified.
For SLCs with SLC calendar schedules, Concurrence Count tells IBM Sterling Control Center
Monitor how many occurrences of the
workflow are expected to run during the scheduled time. If “Generate notification if event has not
occurred” is selected for an SLC with a calendar schedule, then SLC events are generated for each
instance that does not run as expected. For SLCs with SLC duration schedules, Concurrence Count
tells IBM Sterling Control Center
Monitor how many occurrences of
the workflow might run simultaneously.
- On the Milestones window, specify three milestones, one
for each Process (PROCESSA, PROCESSB, and PROCESSC).
- Define parameters that specify PROCESSA on SERVERA for
the first milestone, which we call PROCA, as illustrated in the following
table:
| Key |
Operator |
Value |
| Server |
Wild card |
SERVERA |
| Process Name |
Wild Card |
PROCESSA |
- On the Schedule window, specify a
minimum and maximum duration of 000:00:00 to 000:10:00 (0 minutes
to 10 minutes) for milestone PROCA.
- Additional milestones, similar to the first, must be defined
for PROCESSB on SERVERB, and PROCESSC on SERVERC.
