Using rotatelogs for rotating access_log file on IBM HTTP Server

[anuptosh]

hi,

My access_log file of IBM HTTP Server under WAS has grown to a very large size: around 700 MB. I have tried using rotatelogs to generate new logs files on weekly basis.

But, I have encountered certain issues here:

1. I have maintained the default rotating logic i.e. "CustomLog "|/opt/IBMHTTPD/bin/rotatelogs /opt/IBMHTTPD/logs/access_log 604800" common" , but this does not generate new access_log.nnnn file if the webserver does not get http requests for a long time during this time frame. Hence, 604800 secs appears as a misguiding time frame.

2. I have also tried using access_log.%d-%b-%Y-%H-%M 86400" common. This means it should generate access_log file by the name - access_log.30-Apr-2004-00-00, but it does not. It generates file name as access_log.%d-%b-%Y-%H-%M, which is wrong. Is there something I am missing here.

3. I cannot restart the HTTP Server to generate new log files, which appeared as the solution on various websites.

Can somebody provide me with the correct solution to generate the access_log files with correct distinguishing names after certain time intervals using rotatelogs

This is actually urgent !!

you must send apache a restart signal so it creates the new logs, it will not do it automatically:

/bin/kill -USR1 `cat /usr/local/apache2/logs/httpd.pid 2>/dev/null` 2> /dev/null || true

that is what I use for logrotate. that should go in the logrotate scrip after the log gets rotated so it will restart apache.

The USR1 is a graceful restart, which is recomended. See
here for more info:

Brian,

Thanks for ur feedback.

Will you be able to throw some light on the naming of the Log file generated as raised by me above.

My idea is to write a script that checks for more than one log generated and will then archieve it (not the latest - bcos this is being written into) .. For that reason, I will also check the name of the log files generated.

The log file with the new name does generate automatically i.e after the time interval if there is a http request. This I have done without restarting the HTTP Server.

So, my actual issue is naming the file using rotate logs (not default naming)

Please provide some more inputs on this

My apologies, I should have read more carefuly...

according to rotatelogs at

http://httpd.apache.org/docs-2.0/programs/rotatelogs.html

, the configuration you have above should work for you. check your error_log and make sure it is not failing for some reason... but this should work:

CustomLog "|/opt/IBMHTTPD/bin/rotatelogs /opt/IBMHTTPD/logs/access_log.%d-%b-%Y-%H-%M 604800" combined
