Description

Since moving Icinga to alert1001 I've noticed that "dump of" and "snapshot of" checks are reporting unknown status.

Looking closer it seems that check-mariadb-backups is failing with the below. Currently wmfbackups 0.2 is what's available via apt in buster.

alert1001: /usr/bin/check-mariadb-backups --help

Traceback (most recent call last):

Was there an OS upgrade on the change from icinga1001 to alert1001? I must not have uploaded all versions for all os versions, or something.

Yes there was an OS upgrade from Stretch (icinga1001) to Buster (alert1001)

I see the issue, after apt upgrade, the 0.2 version was available, which was the one that worked. It must have been caught in the small window between first deploy (0.1) and 0.2 fix, and I didn't notice alert1001 was about to be made the primary host.

0.1 had missing dependencies. Those are fixed on 0.2. Now it works. Apologies.

Is there an alert2001 to do the same fix?

apt install wmfbackups-check  #so it installs 0.2

This should be fixed now in alert1001 and alert2001. The issue was that my puppet only had ensure_package(wmfbackups-check) but I didn't upgrade to 0.2 on alert* hosts, only the icinga ones.

No problem at all, thanks much for the quick fix! Confirmed that these Icinga checks are green once again.

Yes indeed there is, let's add a package require to puppet as well.

I will, it is just that by the time we add >= 0.2, I will have a 0.3 version.

I think for now I will check on debdeploy all places where it is installed and control it manually, and when it is more stable, I will add the >=0.3 or more.
