Hi all,

I’m fine tuning the logging but it’s not quite right…

What I want is for the file to roll at midnight to a new date pattern file and roll within the same day if it reaches 50MB.

Eg. 

Start up application, 21-NOV-2008,   file gets created

myComp.Job Scheduler Service.20081121.log.txt

ideally, service continues to run, midnight rolls around and there’s a new file created for the 22^nd and entries go to that.

myComp.Job Scheduler Service.20081122.log.txt

Problem is I’m not getting that… I’m getting a roll of the current file suffixed with the starting date? And logging continues to the same “21^st” file pattern

myComp.Job Scheduler Service.20081121.log.txt ß latest entries in here

myComp.Job Scheduler Service.20081121.log.txt20081121 ß rolled file at midnight.

I’ve tried setting the rollingStyle to Date or Composite, but that hasn’t worked either.

This is possible??

Below is the config options. I’d appreciate any help.

Also, I may have misinterpreted the maxSizeRollBackups…  I’ve assumed that would keep 10 days worth of log files and then start deleting older log files for me, but I’m beginning to think that only applies to the rolls with a day?

So I’ll have to clean up any log files OLDER than 10 days?

Thanks in advance.

    <!-- because it's text, Log file service will zip this down to around 5MB  -->

Okay,

I wrote a small test app so I could get this right.  Seems to have helped as I think I understand this better now.

1. Yes it is possible to have the appender roll the filename on the date change
2. Yes it is possible to specify where the appender places the date pattern

If I use

    <staticLogFileName value="false" />

Then the file name is always generated on the date roll over.

If I use a better date format string with a literal tacked on the end, I get the file names I’m after.

    <datePattern value="yyyyMMdd’.log.txt’" />

All you need to do is modify the original file value to exclude the original %date I was using, as the appender adds this for me.

    <file type="log4net.Util.PatternString"

          value="${ALLUSERSPROFILE}\Application Data\Job Scheduler\%env{COMPUTERNAME}.Job Scheduler Service" />

Then I get the filename pattern I’m after.

myComp.Job Scheduler Service.20081121.log.txt

myComp.Job Scheduler Service.20081122.log.txt

myComp.Job Scheduler Service.20081123.log.txt

The only question that remains is…

Can I specify a pattern for WHERE the appender should place the suffix of what number this is when doing a maxSizeRollBackups ??

<maxSizeRollBackups value="10" />

I’ll keep 10 files for a given day. But the file name is coming out as…

myComp.Job Scheduler Service.20081121.log.txt

myComp.Job Scheduler Service.20081121.log.txt.1

myComp.Job Scheduler Service.20081121.log.txt.2

myComp.Job Scheduler Service.20081121.log.txt.3

whereas I’d prefer

myComp.Job Scheduler Service.20081121.log.txt

myComp.Job Scheduler Service.20081121.1.log.txt

myComp.Job Scheduler Service.20081121.2.log.txt

myComp.Job Scheduler Service.20081121.3.log.txt

Thanks in advance if someone can help with this.
