Alerts and log messages might indicate BIG-IP devices are Unavailable without providing details. A log message with text like this is returned: 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 most likely include intermittent network connectivity loss or network slowdowns, high CPU usage on the BIG-IP device, and so forth.
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.
