can tomcat give me page loadtime stats?
Is there a way for tomcat to give me information on how long it takes to load a page? I have a web application upon which I wish to improve it's performance. Before I can do any attempts at improvement, I need a way to measure its performance. One of the ways that I was considering measuring this delta was to see how long Tomcat takes to load a page. Can tomcat product this information for me (configuration setting, log files, etc)? Or do I need to manually add timestamp information to the top and bottom of my page templates? Suggestions appreciated.

See the AccessLogValve javadocs. -Tim Glanville, Jay wrote: Is there a way for tomcat to give me information on how long it takes to load a page?

RE: can tomcat give me page loadtime stats?
Good. Thanks. Now, a little help is requested in how to use AccessLogValue. (and now that I read the first answer, I realize that I might not have phrased my question as unambiguously as possible). I'd like to have the following information logged: page x took y milliseconds to create (or something like that) According to http://jakarta.apache.org/tomcat/tomcat-4.1-doc/catalina/docs/api/org/ap ache/catalina/valves/AccessLogValve.html, I would use %U for x (the page's URL), but what would I use for y (the amount of time it took to create the page)? %t only gives me the date and time it was requested, not how long it took Tomcat to calculate the page's contents.

D'oh! The catalina javadocs are out of date (but not by much) on the website. In your local version of the javadoc, there should be the following: %D - Time taken to process the request, in millis %T - Time taken to process the request, in seconds -Tim Jay Glanville wrote: Good.

RE: can tomcat give me page loadtime stats?
Howdy, And so, you probably want pattern=page %U took %D milliseconds to serve in server.xml. Be very careful with your terminology in this area, because people draw conclusions about performance from this log file. The time to create a page can be defined in many different ways. The time to serve a page, which is what the access log measures, is more precise. How long it took tomcat to calculate the contents is similarly ambiguous.

RE: can tomcat give me page loadtime stats?
I have a feeling that these variables (%D and %T) are not available in 4.1.12 as they don't actually resolve to anything in the access log. I can determine that they were added in AccessLogValue (ver 1.3), but I don't know what the CVS tag is for version 4.1.12 (ver 1.3 has these tags: s1ap8_i3, s1ap8_i2, s1ap8_i1, jwsdp_12__02, jwsdp_12__01, TOMCAT_5_0_2, TOMCAT_5_0_1) Thanks for you help.

Re: can tomcat give me page loadtime stats?
yeah, %D and %T are newer than 4.1.12. If your stuck with that version - you'll need to write a filter which logs to file. -Tim Jay Glanville wrote: I have a feeling that these variables (%D and %T) are not available in 4.1.12 as they don't actually resolve to anything in the access log.

You could also write a filter to measure performance. http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters.html Subir -Original Message- From: Jay Glanville [mailto:[EMAIL PROTECTED] Sent: Thursday, October 09, 2003 9:12 AM To: 'Tomcat Users List' Subject: RE: can tomcat give me page loadtime stats?
