ColdFusion 2018 CFLog

Hi,

How can we get cflog files created per day?

Thank you.

If you're using CFLOG to create your own log files, you can specify the exact name of those files, as described here:

As for the "built-in" log files, there's no control over the log rolling process as far as I'm aware. So, you might want to use your own log files instead.

Thanks Dave. It is custom log file. As per link, it is suggesting to use cffile. We have this coded for 20 files and I want to avoid modifying this files.

Is there way, I can roll it by size?

I don't think you have any control over the built-in log rolling functionality.

Thanks..Will have to use cffile then.

Two things. First, you can indeed rotate the CF logs by size. That's the

default behavior. See the CF admin logging settings page for that, and to

change the size, if interested.

Second, as for log rotation by day, that's not a built-in feature. But there

is an AdminAPI method to rate the logs (just as most CF admin UI features

have an underyling admin API method). You could setup a scheduled task to

call that method nightly.

Here is a blog post that discusses that adminapi archiveLogFile ethod:

logs-daily/

Let us know if either of those suit your needs.

I didn't know about the admin API feature. Thanks!

One idea - Use cflog with custom file names based on the date, week or month you are trying to capture.  So you end up with logs based some span of time.
