Hi All, I am trying to debug why rsyslog (v8.2012.0) is suddenly getting killed in our Kubernetes cluster (running as daemonset pod). When I enable debugging mode in rsyslog, it prints a lot of output. I am trying to limit rsyslog Debug output to a source file (contrib/mmkubernetes/mmkubernetes.c) using "FileTrace" but it doesn't seem to be working. How do I use that option or are there any other ways to limit rsyslog debug output ?
Here is what I have tried so far, To enable debugging in rsyslog, I have set following env vars RSYSLOG_DEBUGLOG RSYSLOG_DEBUG >From documentation <https://www.rsyslog.com/doc/master/troubleshooting/debug.html>, I could see that RSYSLOG_DEBUG supports "FileTrace" option which would limit debugging output to some files. I tried setting FileTrace and/or LogFuncFlow, but its not working export RSYSLOG_DEBUGLOG="/tmp/logs" export RSYSLOG_DEBUG="Debug FileTrace=vm.c NoStdOut" /usr/sbin/rsyslogd -n > *rsyslogd 8.2004.0.11. error: invalid debug option 'FileTrace=vm.c' - > ignored*rsyslogd: parameters for built-in module builtin:omfwd already > set - ignored [v8.2004.0.11. try https://www.rsyslog.com/e/2220 ] I tried help to see options it supports, surprisingly FileTrace isn't supported. export RSYSLOG_DEBUG="Debug help" rsyslogd 8.2004.0.11. runtime debug support - help requested, rsyslog > terminates > environment variables: > additional logfile: export RSYSLOG_DEBUGFILE="/path/to/file" > to set: export RSYSLOG_DEBUG="cmd cmd cmd" > Commands are (all case-insensitive): > help (this list, terminates rsyslogd) > NoLogTimestamp > Nostdout > OutputTidToStderr > DebugOnDemand - enables debugging on USR1, but does not turn on output > See debug.html in your doc set or https://www.rsyslog.com for details I tried digging source code <https://github.com/rsyslog/rsyslog/blob/v8.2012.0/runtime/debug.c> - I couldn't find any trace of FileTrace Hence my Question is - Is FileTrace supported ? If yes, how to use it or are there any other ways to limit Rsyslog Debug output to source file (Ex: contrib/mmkubernetes/mmkubernetes.c) -- Regards, Rajesh KSV _______________________________________________ rsyslog mailing list https://lists.adiscon.net/mailman/listinfo/rsyslog http://www.rsyslog.com/professional-services/ What's up with rsyslog?
