Edge Device Statistics¶

You can monitor the Edge Device statistics from the Edge Device UI by clicking Statistics in the navigation menu.

The Statistics screen is displayed as below for example:

Device Statistics Page

The GetResourceStats RPC method of the system service returns current CPU, Memory, Uptime and Storage information.

Below you can find an example on how to calculate Storage and Memory statistics.

Storage Statistics¶

Storage statistics can be gathered from the Edge Device with the df command:

$-> df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        19G  8,5G  9,6G  47% /

Mapping of these values to the Edge Device UI is displayed below:

Storage Statistics

Capacity : Total storage available
Available : Available free storage
Used : Used storage by the Edge Device
Percentage: Percentage of used space

Percentage can be calculated like this:

Percentage = (Used * 100) / Capacity

Memory Statistics¶

Memory statistics can be gathered from the Edge Device with the top command:

$-> top
top - 12:10:11 up 1 day,  8:36,  1 user,  load average: 0,18, 0,29, 0,25
Tasks: 225 total,   1 running, 224 sleeping,   0 stopped,   0 zombie
%Cpu(s):  1,7 us,  0,3 sy,  0,0 ni, 97,9 id,  0,0 wa,  0,0 hi,  0,0 si,  0,0 st
GiB Mem :     13,1 total,      7,9 free,      2,0 used,      3,1 buff/cache
GiB Swap:      0,9 total,      0,9 free,      0,0 used.     10,7 avail Mem

Mapping of these values to the Edge Device UI is displayed below:

Memory Statistics

Capacity : Total memory available
Used : Used memory by the Edge Device
Peak : Maximum memory used in the selected Monitoring Period
Average : Average memory used in the selected Monitoring Period

Percentage can be calculated like this:

Percentage = (Used * 100) / Capacity
