Monitoring capabilities in the web interface
Several device monitoring and connection-management capabilities are available in the web
interface including system information and statistics, and connection management information.
Display system information
The System Information pages display general system information, serial port information, system
statistics, and diagnostics. This information is typically used by technical support to troubleshoot
problems. To display these pages, go to Administration > System Information.
General system information
Model
The model of the Digi device.
MAC Address
A unique network identifier required for all network devices. The MAC address is on a sticker
on the Digi device and is displayed as 12 hexadecimal digits, usually starting with 00:40:9D.
Firmware Version
The current firmware version running in the Digi device. This information may be used to help
locate and download new firmware. Firmware updates can be downloaded from:
http://support.digi.com/support/firmware
Boot Version
The current boot code version running in the Digi device.
POST Version
The current Power-On Self Test (POST) code version running in the Digi device.
CPU Utilization
The amount of CPU resources being used by the Digi device.
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.
Up Time
The amount of time the Digi device has been running since it was last powered on or rebooted.
Total/Used/Free Memory
The amount of memory (RAM) available, currently in use, and currently not being used.
