error handling stats line - after update to rsyslog-8.2204

[mvrk69]

Hi,

I updated my rsyslog to 8.2204 and started having this error messages from the exporter:

Jan 25 07:21:45 syslog002 rsyslog_exporter[2097]: 2023/01/25 15:21:45 error handling stats line: unknown pstat type: 0, line was: 2023-01-25T07:21:45.871761-08:00 syslog002 rsyslogd-pstats: { "name": "global", "origin": "percentile", "values": { } }

Do you know what could be the problem?

Best regards.

The code that determines the pstat type and decides what to do with it doesn't know what to do with this line. And frankly, neither do I, it does not seem to actually include any useful data. I think the error is benign (nothing of value is lost) but noisy, so it makes sense to handle this case.

Hi @mvrk69,

I can reproduce this also in 8.2112.

As @matthiasr suggested, worst case I will silent this message if no useful data comes from this pstat.

Did a bit of research:

• The stat is pushed by default since 8.2112 (I don't have it in 8.2102);
• It is empty by default (like the dynstat one) if you are not using percentile stats feature;
• It seems to be really similar to dynstat pstat (need more testing);

I will see how to implement it.

waiting for a new version of the exporter?

For the moment, this PR #7 can be used as a workaround to silence those errors messages.
You need to pull/build from master.

Sorry to ping people in this issue after almost a year of no activity.

@aleroyer Would it be possible to create a new release of this exporter to include the changes from #7? Or are we waiting for #11 before new release?

I will make a new release so we can at least hide those messages.

I haven't had time to dedicate into refactoring some stuff in the exporter to finish #11 properly.

please proceed with new release

@aleroyer Understandable, thanks for answering! I wouldn't mind multiple smaller releases if that makes it easier!

@grzesrap @vilhelmprytz 1.1.0 released.

I had to fix github actions to make it work!
