Ever since version 23.6.0 for sure, but possibly 23.5.0 any time I add a new linux server to my LibreNMS instance (I have a couple and they all do the same thing), I get constant alerts for device down due to no ICMP response every 60 seconds until I run the the daily.sh script on the poller that is responsible for monitoring the device. What’s even more odd is my delay on that alert is 31 minutes, so why is it firing every 60 seconds, even if the device was down?
Standard ping and fping show normal results (<1ms latency) when I run them manually from the same poller. I have tried rebooting the main LibreNMS server and remote probe and this doesn’t help, but the alerts almost immediately stop when the ./daily.sh script get’s run, so it seems to be something happening in there that gets cleaned up or something.
This happens on the main LibreNMS Server and remote pollers. ./validate.php doesn’t show anything wrong while the issue is happening. Wondering if anyone else is experiencing the same issue, or has any ideas where to look?
