AlertManager error scrolling over and over in /srv/logs/pmm-managed.log

I’ve updated to the latest 2.25 version, and I’m seeing these messages scroll over and over in /srv/logs/pmm-managed.log

I do not have “Integrated Alerting” enabled, and I’m not sure where this is coming from. Any suggestions?

Hi Danny,

Could check any errors in next log files?

No errors in /srv/logs/pmm-update-perform.log that I can see.

I’m assuming Alertmanager and Integrated Alerting are two separate things, so with Integrated Alerting shut off it makes no difference. However, I didn’t configure anything specific for Alertmanager, so not sure why that would be having issues.

Hi @dbray_sd

Did you modify the below file, can you please check once in the below file?
cat /etc/grafana/grafana.ini

May be this might be the reason, I am not sure but just try to check this once.

It looks like the configuration files is protected for writing.
So pmm-managed service can’t recreate it.

e.g.

Could you remove this file and restart pmm-managed service?

No, I did not manually modify that file.

Odd, it recreated it…but recreated it with the exact same contents:

[root@1fd26d7c5d00 opt]# supervisorctl stop pmm-managed
pmm-managed: stopped
[root@1fd26d7c5d00 opt]# rm /etc/alertmanager.yml
rm: remove regular file ‘/etc/alertmanager.yml’? y
[root@1fd26d7c5d00 opt]# supervisorctl start pmm-managed
pmm-managed: started
[root@1fd26d7c5d00 opt]# cat /etc/alertmanager.yml

Hi @dbray_sd

Can you stop and start the docker?

Already tried that. It still recreates the file with the same “empty” contents as above.

Thanks.

Hi @dbray_sd

Is the below file still exists with the same name?
/tmp/pmm-managed-config-alertmanager-076327072

can you remove it and then restart the pmm server?

My file was named:
/tmp/pmm-managed-config-alertmanager-087463742

…I removed it and /etc/alertmanager.yml restarted. Problem remains, /etc/alertmanager.yml recreated with same empty contents, and no new /tmp/pmm-managed-config-alertmanager-* file was created.

Did you enable the Alerting in the GUI before upgrade to 2.25?

1 Like

If you mean the “Integrated Alerting”, yes, that was enabled, but was never used/configured. So it was disabled after upgrading to 2.25. However, this issue was happening before the upgrade to 2.25.

Can you disable(in gui) it now and then restart the pmm server?

Already tried that as well. It has been disabled this entire time in the gui, before I posted to this forum. I’ve also enabled it restarted, disabled it restarted, etc., and that makes no difference.

Can you share the problem/error related to /etc/alertmanager.yml ?

Sorry, I’m not sure what you are asking. @adivinho first asked about the /etc/alertmanager.yml file, and the contents from above. That file does not look like what it should, I assume, and is not getting recreated properly upon restart.

Could you make sure that all pmm components have proper versions?
