Alerts and log messages may indicate BIG-IP devices are Unavailable without providing details. A log message with text like this will be seen: The following devices are not reachable from the BIG-IQ: some-bigip.mydomain
Devices are temporarily marked unavailable, until the next successful poll.
Specific conditions are not known, but probably include intermittent network connectivity loss or network slowdowns, high CPU usage on the BIG-IP device, etc.
Any details that are available are noted in the device-refresh API endpoint until the next refresh (every two minutes). For example, the following command can be run from the BIG-IQ shell: # restcurl shared/identified-devices/config/device-refresh Devices that are listed with isAvailable=false also have an errorResponse field with more information.
