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:
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
34.
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.
AvgReq Time
Average request time
A running average of the time, in milliseconds, that it takes ColdFusion
to process a request (including queued time). Lower values, which you
can achieve with efficient CFML, are better. Averages are displayed for
the last two completed requests.
AvgDB Time
Average database transaction time
A running average of the time that ColdFusion spends on database-
related processing of ColdFusion requests. Averages are displayed for
the last two completed requests.
Bytes In/Sec
Bytes incoming per second
The number of bytes that ColdFusion read in the last second (not an
average).
Bytes Out/Sec
Bytes outgoing per second
The number of bytes that ColdFusion wrote in the last second (not an
average).
