JkRequestLogFormat Options
Hallo,
I am logging the mod_jk Output through the Apache access_log - as written in the reference found under
http://tomcat.apache.org/connectors-doc/reference/apache.html
Because i want to get clearness about what exactly is going on in our system i use the following LogFormat:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" \"%{Cookie}i\" \"%{Set-Cookie}o\" %{pid}P %{tid}P%T
%{JK_WORKER_NAME}n %{JK_REQUEST_DURATON}n %{JK_WORKER_ROUTE}n %{JK_LB_FIRST_NAME}n %{JK_LB_FIRST_BUSY}n %{JK_LB_FIRST_VALUE}n
%{JK_LB_FIRST_ACCESSED}n %{JK_LB_FIRST_READ}n %{JK_LB_FIRST_TRANSFERRED}n %{JK_LB_FIRST_ERRORS}n %{JK_LB_FIRST_ACTIVATION}n
%{JK_LB_FIRST_STATE}n %{JK_LB_LAST_NAME}n" mod_jk_log
...everthing works fine except the Options responsible for the Request Duration.
Mostly neither %T nor %{JK_REQUEST_DURATON}n have a Value (%T mostly is 0 an the other Parameter is "-").
At some Requests i found the %T has a value like for example 2 or 3.. - and JK_REQUEST DURATION has "-"
or %T is 0 and JK_REQUEST_DURATION has an value like 2 or 3 ...
First - why are there not values at each request ?
Second -i think both Options are measuring the same Value - why they are not the same ?
Third - why they are not showing seconds.microseconds as written in the reference but only (I think so) rounded seconds.
We use mod_jk 1.2.26
Thanks for help
Best

Hi,
btw, in your log format line you have %{JK_REQUEST_DURATON}n instead of
%{JK_REQUEST_DURATION}n see the missing I.
I am using 1.2.25 and i get times alike 0.0275 when using Apache 2.2

Re: JkRequestLogFormat Options
Posted by Ahmed Musa <do...@gmx.at>.
Hallo Rainer,
thanks for your Input
- of course i have to change my FIRST and LAST variant (the FIRST_NAME i will use to check if the worker has changed) - but you're right - i am more interested in the LAST values.
Changed %T to %D -> works fine, thanks
We upgraded to 1.2.26 last week - but the Values for ROUTE and DURATION are the same than before (1.2.25) - and we haven't set JkRequestLogFormat explicitly.(of course i wrote DURATION without I - now it's ok).
thanks
best ahmed

Re: JkRequestLogFormat Options
Posted by Rainer Jung <ra...@kippdata.de>.
In addition to Freds remark:
Usually you want the "LAST" variant, instead of the "FIRST" variant. The
two are the same, if a loab balancer only tries one worker, but in case
of an error and failover, FIRST will be the first worker tried (so the
failed one) and LAST the last one, so usually the successful one (unless
all workers fail).
%T: response time in seconds, and I think it always gets rounded down.
So usually not very useful
Instead you could use the httpd standard %D, which is response time in
microseconds.
Last remark: until JK 1.2.25 the variables JK_WORKER_ROUTE and
JK_REQUEST_DURATION where only filled, if some JkRequestLogFormat was
set. In your version 1.2.26 both of them should get set even with a
JkRequestLogFormat (but only, if the request gets handled by mod_jk, so
not for static content, that is returned by the web server without any
Tomcat interaction).
Regards,
Rainer
