I’m a newbie to using LibreNMS and in SNMP monitoring in general. As I was curious why I was seeing a warning when looking at the machine hosting LibreNMS, I was directed to the FAQ… https://docs.librenms.org/Support/FAQ/#why-does-a-device-show-as-a-warning to be specific. I believe I found a typographical error. It shows:
This is indicating that the device has rebooted within the last 24 hours (by default). If you want to adjust this threshold then you can do so by setting
$config['uptime_warning'] = '84600';in
config.php. The value must be in seconds.
I believe someone got their numbers mixed up in the value. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day; 60 X 60 X 24= 86400… not 84600. 84600 would be 23 hours and 30 minutes… unless that was the intent instead of 24 full hours.
