Isolating performance for specific types of requests
This topic describes how to enable request metrics filters.
Overview
Request metrics compares each incoming request to a set of known
filters, but you need to enable these filters.
Procedure
- Open the administrative console.
- Click Monitoring and Tuning > Request metrics in
the administrative console navigation tree.
- Click Filters.
- Click filter type.
- Select the check box in the Enable field under the Configuration
tab.
- Click Apply or OK.
- Click Save. You can enable or disable a filter
group. If the group is enabled, you can enable or disable individual filters.
Results
The request metrics filters are enabled according to your configuration.
For example, if you enabled source IP, only requests whose source IP matches
the one specified in the filter will be instrumented.
Note: Filters will only
be checked for edge transactions. An edge transaction is the transaction that
first enters an instrumented system. For example, if a servlet calls an Enterprise
JavaBean, the servlet is the edge transaction, assuming it is not instrumented
at the Web server plug-in, and the URI and SOURCE_IP filters will be checked
for the servlet request. However, when the request comes to EJB container,
EJB filter will not be checked because it is no longer an edge transaction.
What to do next
You must regenerate the Web server plug-in configuration file as
described in the Regenerating the Web server plug-in configuration file topic
after modifying the request metrics configuration.
