We've recently switched our Apache 2.x configuration to log indirectly via rsyslog rather than directly to the log files, in order to get the benefits of asynchronous logging (we see periodic latency spikes when logging to our NFS filer).
When the rsyslog-generated Apache log files are on a local disk, the nightly log rotation (which triggers an rsyslog reload == HUP signal) works fine. But when the log files are on an NFS filer, for some reason rsyslogd doesn't re-open them after the HUP -- lsof on the rsyslogd process shows the log files open before but not after the HUP. Doing a restart of rsyslogd does open them again. We're using rsyslog 4.2.0, which is the version distributed with our Ubuntu 10.10. Any ideas on why rsyslog is responding differently to the HUP for local vs. NFS log files and what to do to make it work for NFS log files? I ran rsyslogd with -dn and captured the debug output across the HUP processing both when using local and NFS files, but didn't see anything obvious about why the log files weren't reopened when over NFS. Thanks for any help. Chris _______________________________________________ rsyslog mailing list http://lists.adiscon.net/mailman/listinfo/rsyslog http://www.rsyslog.com
