CONFIGURING AND ADMINISTERING COLDFUSION 9
Using the ColdFusion Administrator

Using the cfstat utility
The cfstat command-line utility provides real-time performance metrics for ColdFusion. The cfstat utility uses a
socket connection to obtain metric data. You can use the cfstat utility to display information that ColdFusion writes
to the System Monitor without using the System Monitor application. The following table lists the metrics that the
cfstat utility returns:
Report Execution Times Reports execution times that exceed a specified time limit.
General Debug Information Show general information about the ColdFusion MX version, template, timestamp, user
locale, user agent, user IP, and host name.
Database Activity Shows the database activity for the SQL Query events and Stored Procedure events in the
debugging output.
Exception Information Shows all ColdFusion exceptions raised for the request in the debugging output.
Tracing Information Shows trace event information in the debugging output. Tracing lets you track program flow
and efficiency using the
cftrace tag.
Timer Information Shows output from the cftimer tag.
Flash Form Compile Errors And Messages (Development use only) Displays ActionScript errors in the browser when Flash forms are
compiling, and affects the display time of the page.
Variables Displays information about parameters, URL parameters, cookies, sessions, and CGI variables
in the debugging output.
Enable Performance Monitoring
(Server configuration only)
Enables the standard NT Performance Monitor application to display information about a
running server.
TIP: Restart ColdFusion after you change this setting.
Enable CFSTAT
(Server configuration only)
Shows performance information on platforms that do not support the NT Performance
Monitor. For more information, see
“Using the cfstat utility” on page 19.
TIP: Restart ColdFusion after you change this setting.
Metric abbreviation Metric name Description
Pg/Sec Page hits per second The number of ColdFusion pages processed per second. You can
reduce this limit by moving static content to HTML pages.
DB/Sec Database accesses per second The number of database accesses per second that ColdFusion makes.
Any difference in complexity and resource load between calls is
ignored.
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 wait for
ColdFusion to process them. Lower values, which you can achieve
with efficient CFML and enhanced caching, are better. Averages are
displayed for the last two completed requests.
