Performance Charts

iPlanet Integration Server • Process System Guide • August 2001
It is therefore a good idea to regularly monitor a number of performance
indicators—instrumentation within an engine that can be displayed over time in
the iIS Console Performance Charts. The instruments displayed in the Performance
Charts are the following:
These instruments indicate how performance might be impacted by an increasing
load on the engine.
For example, as the number of sessions increases over time, you would expect the
average response time to increase. At some point, you might decide to add an
additional engine to your workflow system to help balance the load.
As the number of process instances and activities increase over time, you would
expect the average transaction commit time to increase. In this case you might
decide to start up additional database services to speed throughput to the engine
database.
In many situations these factors have complicated interactions and you have to
monitor these indicators carefully under varying conditions, analyzing the source
of any performance bottlenecks.
Viewing Performance Indicators
You can view performance indicators for any running engine in the Performance
window.
Instrument
Description
Process Instances
number of active process instances
Activities
number of activities in the ready or active state
Average response
time
the average time it takes for the engine to complete a request
made by a session (such as OpenSession, StartActivity, and
CompleteActivity)
Average transaction
commit time
the time it takes the engine to commit a change of state (complete
a transaction involving the engine database)
Allocated memory
the amount of the active memory currently allocated to objects
created by the primary engine unit
Peak allocated
memory
the amount of allocated memory remaining after the most recent
memory reclamation (probably the best measure of active
memory utilization)
