IIS 7.5 has stopped logging all traffic for a single site (of a couple of dozen on the same box), and I can't work out why. It stopped logging at exactly midday on Friday last week, and nothing since. All log files for other sites are as expected. So far I've checked;
- Logging configuration is the same as other sites (W3C logging to a directory, one file per day)
- NTFS ACLs on the log folder are OK (inherited from the parent, the same as other log folders)
- disabled and re-enabled logging
- stopped and re-started the site
I've not restarted IIS or the server, but it was rebooted last night (Sunday) for Windows Updates, ie this problem pre-dates those updates and reboot.
Is there any way I can debug the logging process itself? All attempts to search for debug and logging just get me stuff about debugging requests, not the logging engine itself.
