Sorry, I was off working on the new fencing logic and then corosync 2.0 support (when cman and all the plugins, including ours, go away). So a couple of comments... I fully agree that the state of our logging needs work and I can understand people wanting to keep the vast majority of our logs out of syslog. I'm less thrilled about one-file-per-subsystem, the cluster will often do a lot within a single second and splitting everything up really hurts the ability to correlate messages. I'd also suggest that /some/ information not coming directly from the RAs is still appropriate for syslog (such as "I'm going to move A from B to C" or "I'm about to turn of node D"), so the nuclear option isn't really thrilling me. In addition to the above distractions, I've been coming up to speed on libqb's logging which is opening up a lot of new doors and should hopefully help solve the underlying log issues. For starters it lets syslog/stderr/logfile all log at different levels of verbosity (and formats), it also supports blackboxes of which a dump can be triggered in response to an error condition or manually by the admin. The plan is something along the lines of: syslog gets NOTICE and above, anything else (depending on debug level and trace options) goes to /var/log/(cluster/?)pacemaker or whatever was configured in corosync. However, before I can enact that there will need to be an audit of the messages currently going to INFO (674 entries) and NOTICE(160 entries) with some getting bumped up, others down (possibly even to debug). I'd certainly be interested in feedback as to which logs should and should not make it. If you want to get analytical about it, there is also an awk script that I use when looking at what we log. I'd be interested in some numbers from the field. -- Andrew #!/bin/bash awk 'BEGIN{ keys[0] = "openais" keys[1] = "heartbeat:" keys[2] = "ccm:" keys[3] = "lrmd:" keys[4] = "crmd:" keys[5] = "pengine:" keys[6] = "cib:" keys[7] = "CTS:" keys[8] = "stonithd:" format[0] = "" format[1] = "" format[2] = "\t" format[3] = "\t" format[4] = "\t" format[5] = "" format[6] = "\t" format[7] = "\t" format[8] = "" l_format[0] = "\t" l_format[1] = "\t" l_format[2] = "\t" l_format[3] = "" l_format[4] = "\t" l_format[5] = "\t" level[0] = "CRIT:" level[1] = "ERROR:" level[2] = "WARN:" level[3] = "notice:" level[4] = "info:" level[5] = "debug:" max = 9; l_max = 6; for( i = 0 ;i < max; i++){ values[i] = 0; } for( i = 0 ;i < l_max; i++){ l_values[i] = 0; } } { i =0 while( i < max ){ if ( NF < 5) { break } if ( $5 == keys[i]){ values[i]++ i =0 while( i < l_max ){ if ( NF < 5) { break } if ( $7 == level[i]){ l_values[i]++ break } i++ } break } i++ } }END{ total = 0 for( i = 0 ;i < max; i++){ total=values[i] + total } print "total line number is " total print "progs", "\t","\t", "#of lines","\t" "percentage" for( i = 0 ;i < max; i++){ print keys[i], format[i],"\t", values[i],"\t\t" values[i]/total*100 "%" } print "\nLog levels:" for( i = 0 ;i < l_max; i++){

So everything that is logged by the RAs with ocf_log, as I wrote in the original post, _is_ still going to whatever the default syslog destination may be. The rsyslog config doesn't change that at all. (Stuff that the RAs simply barf out to stdout/err would go to the lrmd log.) I maintain that this is the stuff that is also most useful to people. And with just that information in the syslog, you usually get a pretty clear idea of what the heck the cluster is doing on a node, and in what order, in about 20 lines of logs close together -- rather than intermingled with potentially hundreds of lines of other cluster-related log output. And disabling the "nuclear option" is a simple means of adding a "#" before "& ~" in the config file. You can ship it that way by default if you think that's more appropriate. That way, people would get the split-out logs _plus_ everything in one file, which IMHO is sometimes very useful for pengine or lrmd troubleshooting/debugging. I, personally, just don't want Pacemaker to flood my /var/log/messages, so I'd definitely leave the "& ~" in there, but that may be personal preference. I wonder what others think. > In addition to the above distractions, I've been coming up to speed on > libqb's logging which is opening up a lot of new doors and should > hopefully help solve the underlying log issues. > For starters it lets syslog/stderr/logfile all log at different levels > of verbosity (and formats), it also supports blackboxes of which a > dump can be triggered in response to an error condition or manually by > the admin. > > The plan is something along the lines of: syslog gets NOTICE and > above, anything else (depending on debug level and trace options) goes > to /var/log/(cluster/?)pacemaker or whatever was configured in > corosync. > However, before I can enact that there will need to be an audit of the > messages currently going to INFO (674 entries) and NOTICE(160 entries) > with some getting bumped up, others down (possibly even to debug). > I'd certainly be interested in feedback as to which logs should and > should not make it. Yes, even so, I (again, this is personal preference) would definitely not want pengine logging (which even if half its INFO messages get demoted to DEBUG, would still be pretty verbose) in my default messages file. > If you want to get analytical about it, there is also an awk script > that I use when looking at what we log. > I'd be interested in some numbers from the field.

The rsyslog config doesn't change that at all. By "Nuclear", I meant nothing at all from Pacemaker.

Sigh, please take time out from preaching to actually read the replies. You might learn something. Your precious default messages file wouldn't be getting /any/ INFO logs from pacemaker. And I'm guessing your complaints are based on 1.0 logging too right? Because for a long time now, the PE in 1.1 has only logged NOTICE and above by default, which means about 1 additional line per resource + error

For starters it lets syslog/stderr/logfile all log at different levels of verbosity (and formats), it also supports blackboxes of which a dump can be triggered in response to an error condition or manually by the admin. The plan is something along the lines of: syslog gets NOTICE and above, anything else (depending on debug level and trace options) goes to /var/log/(cluster/?)pacemaker or whatever was configured in corosync. However, before I can enact that there will need to be an audit of the messages currently going to INFO (674 entries) and NOTICE(160 entries) with some getting bumped up, others down (possibly even to debug).

Just latest github's version. You changed some dlm_controld.pcmk functionality, so it asks stonithd for fencing results instead of XML magic. But call to crm_terminate_member_no_mainloop() remains the same there. But yes, that version communicates stonithd directly too. SO, the problem here is just with crm_terminate_member_no_mainloop() which for some reason skips actual fencing request. >>> >>> There should be some logs, either indicating that it tried, or that it >>> failed. >> >> Nothing about fencing. >> Only messages about history requests: >> >> stonith-ng: [1905]: info: stonith_command: Processed st_fence_history >> from cluster-dlm: rc=0 >> >> I even moved all fencing code to dlm_controld to have better control on >> what does it do (and not to rebuild pacemaker to play with that code). >> dlm_tool dump prints the same line every second, stonith-ng prints >> history requests. >> >> A little bit odd, by I saw one time that fencing request from >> cluster-dlm succeeded, but only right after node was fenced by >> pacemaker.
