28 Chapter 2: Using the ColdFusion MX Administrator
Using the cfstat utility
The
cfstat
command-line utility provides real-time performance metrics for ColdFusion MX.
Using a socket connection to obtain metric data, the
cfstat
utility displays the information that
ColdFusion MX writes to the System Monitor without actually using the System Monitor
application. The following table lists the metrics that the
cfstat
utility returns:
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 MX. 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 MX
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 MX 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 MX 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 MX to
process them. Lower values, which you can achieve
with efficient CFML and enhanced caching, are
better.
AvgReq Time Average request time A running average of the time, in milliseconds, that
ColdFusion MX spends to process a request
(including queued time). Lower values, which you can
achieve with efficient CFML, are better.
AvgDB Time Average database
transaction time A running average of the time that ColdFusion MX
spends on database-related processing of
ColdFusion requests.
Bytes In/Sec Bytes incoming per second The number of bytes that ColdFusion MX read in the
last second (not an average).
Bytes
Out/Sec Bytes outgoing per second The number of bytes that ColdFusion MX wrote in the
last second (not an average).
