Product Components and Capabilities 1-3
Blackout Periods
During a blackout period, PATROL continues to monitor the WebLogic
environment but does not report object state changes nor does it generate
warnings or alarms. Use blackout periods during routine maintenance to
prevent spurious alarms.
Tuning Collectors
By turning off collectors for parts of the system that are not critical to
your WebLogic environment, you can reduce resource demands and
improve overall PATROL performance. If you experience slow
performance, try turning off unnecessary collectors.
Clustering Support
PATROL for BEA WebLogic supports a clustered server environment
and provides features to manage clustered nodes. The cluster improves
scalability by allowing additional servers to be quickly added to the
WebLogic environment and it improves availability by providing
redundancy and a fail-safe mechanism for rolling functions over to other
servers in the event of a server failure.
J2EE Performance Instrumentation
The PATROL for BEA WebLogic product includes instrumentation
technology that allows you to monitor performance at a fine-grained
component level and to identify potential performance bottlenecks that
may be associated with a single EJB, database URL, SQL statement, or
web application servlet. Using this technology, you can identify critical
components that are most often invoked in your own environment, and
you can identify components with slow response times.
This product can also measure performance of specific Java methods in
individual EJBs and servlets.
