I have a problem in my LibreNMS installation.
If I open the page for graphs about Postgres app (http://librenms/apps/app=postgres) I have a first row with a question mark and a bunch of broken images:
The images have a link pointing to a device with ID 119 that is no more existent on the LibreNMS inventory.
How can I get rid of these broken/orphan graphs?
Thanks in advance.
Best regards. Lorenzo
