I updated from version 21.6.0 to 22.6.0, and noticed a poller module is now included for availability.
-
I unchecked the ‘availability’ poller module at a device’s level under the edit → modules option and ran ‘rediscover’ device, then noticed availability value of ‘0’ is being graphed - causing an overall negative value for device availability
-
Then I checked the ‘availability’ poller module at a device’s level under the edit → modules option and ran ‘rediscover’ device, still noticed no difference for a few hours now - availability value of ‘0’ is being graphed - causing an overall negative value for device availability.
-
For other devices, availability value improved either shortly after the update or about 12 hours after
-
Hostname of the device was updated on the device 10 minutes after the LibreNMS update and not sure if this caused the issue,
The device is online and has an uptime of 288+ days
