Description
Same as #124 .
Graphs intermittently fail to load when using rrdcached on the latest docker image ( 24.9.0 - Tue Oct 15 2024 13:15:45 GMT-0600).
Disabling rrdcached resolves it (but of course, adds more load to an already heavily loaded drive).
This is not a poller issue or anything else. LibreNMS is attempting for unknown reasons to display a non-existent graph for a port that is and always has been down.
Expected behaviour
Graphs load
Actual behaviour
Graphs don't load and show an error about a non-existent file not existing, on about half of all graph loads.
Clicking the graph takes you to another page with another ~50% chance of graphs loading (most of them don't, most of the time).
Steps to reproduce
- Install docker image
- Set up rrdcached
- Refresh the Devices page, mouse over a device, and look at the popup
