Basic ColdFusion MX Administration
* Restart ColdFusion MX after changing this setting.
Using the cfstat utility
The cfstat command-line utility provides real-time performance metrics for ColdFusion.
Using a socket connection to obtain metric data, the cfstat utility displays the
information that ColdFusion writes to System Monitor without actually using the
System Monitor application. The following table lists the metrics that cfstat returns:
Enable Performance Monitoring*
Enables the standard NT Performance Monitor
application to display information about a running
ColdFusion Application Server.
Enable CFSTAT*
Shows performance information on platforms that do
not support the NT Performance Monitor.For more
information, see
“Using the cfstat utility” on page 20
.
Setting
Description
Metric
abbreviation
Metric name
Description
Pg/Sec
Page hits per
second
The number of ColdFusion pages processed per
second. You can reduce this by moving static
content to HTML pages.
DB/Sec
Database
accesses per
second
The number of database accesses per second
made by ColdFusion. Any difference in
complexity and resource load between calls is
ignored.
CP/Sec
Cache pops per
second
The number of ColdFusion template cache pops
per second. A cache pop occurs when
ColdFusion ejects a cached template from the
template cache to make room for a new
template.
Req Q'ed
Number of queued
requests
The number of requests that are currently waiting
for ColdFusion to process them. Lower values,
which you can achieve with efficient CFML, are
better.
Req Run'g
Number of running
requests
The number of requests that ColdFusion is
currently actively processing.
Req TO'ed
Number of timed
out requests
The total number of ColdFusion requests that
have timed out. Lower values, which you can
achieve by aggressive caching, removing
unnecessary dynamic operations and third-party
events, are better.
AvgQ Time
Average queue
time
A running average of the time, in milliseconds,
that requests spend waiting for ColdFusion to
process them. Lower values , which you can
achieve with efficient CFML and enhanced
caching, are better.
