Monitoring ColdFusion Performance
ColdFusion provides a set of counters for monitoring the performance of the
ColdFusion Server. This allows you to use the Windows NT Performance Monitor
administration utility to monitor ColdFusion performance. This enhancement to NT
Performance Monitor is installed automatically by the ColdFusion setup.
A Windows NT Performance Monitor configuration file has been added to ColdFusion
for Windows systems that is pre-configured to monitor ColdFusion Server activity. The
Performance Monitor configuration file, ColdFusionServer.pmc is installed in
cfusion\bin.
To monitor ColdFusion Server activity, click on the ColdFusion Performance Monitor
icon in the ColdFusion Server Program group. You can also open the Performance
Monitor utility and then open the
cfusion/bin/ColdFusionServer.pmc file.
