Description
The current boot code version running in the Digi device.
The current Power-On Self Test (POST) code version running in the Digi device.
The amount of CPU resources the Digi device uses.
Important: 100% CPU Utilization may indicate encryption key generation is in-progress. On
initial boot, the Digi device generates some encryption key material: an RSA key for SSL/TLS
operations, and a DSA key for SSH operations. This key-generation process can take as long
as 40 minutes. Until the RSA or DSA key is generated, the Digi device will be unable to initiate
or accept that type of encrypted connection. The Digi device reports itself as 100% busy, but
since key generation occurs at a low priority, the device will still function normally. On
subsequent reboots, the Digi device will use its existing keys and not need to generate another
unless a reset to factory defaults is done, which will cause a new key to be generated on the
next reboot.
The amount of time the Digi device has been running since it was last powered on or rebooted.
The amount of memory (RAM) available, currently in use, and currently not being used.
