New error after update to 25.8.0

Help
1

Hi I updated my librenms system.

Component Version
LibreNMS 25.8.0 (2025-08-18T06:52:11+02:00)
DB Schema 2025_07_10_201918_update_vlans_table (353)
PHP 8.3.16
Python 3.10.12
Database MariaDB 10.9.7-MariaDB-1:10.9.7+maria~ubu2004
RRDTool 1.7.2
SNMP 5.9.1

after this I get this in my daily.log:
QueryBuilderParser: Warning, guessing glue from device_groups.id to device_group_device.device_group_id

What I see is that my active alerts webpage is being deleted every coupls hours. Even the acknowledged ones. And they all show again.

My hunch and research tells me that there have been some update to ths database scheme, but something in the queries went wrong. Is this a known error? We had a similar problem last month when the database scheme was updated as well…

No idea, but I do suggest you do NOT use the device_group table in alert queries as it can cause some problems and extra work.

Use the map feature to restrict an alert to a device group instead.

It might be a good idea to block that table from the query builder :confused:

It seems to me that there have been made some changes that stops active alerts to check if the alert has already been issued.

It would be nice to be able to have an acknowledged alert to not keep alerting. Or at least to not overwrite the acknowledgement field. Is that possible? I can’t seem to find it.

No one has been able to reproduce this or submit a fix. Any help would be great.
