Hi, I have problems with empty alerts. This started at 20.12.25 around midnight. I dont have validate problems on database server, frontend server, rrd server or any of the pollers nor the discovery server.

PHP | 8.3.14
Python | 3.10.12
Database | MariaDB 10.6.22-MariaDB-0ubuntu0.22.04.1
RRDTool | 1.7.2

see Service alerts cause “Rule created, no errors found” history entries · Issue #13424 · librenms/librenms

Created an everything dynamic group and set filtering on the alerts that had no filtering (all devices).
Sounds like an old bug might have been re-introduced.
