Monitoring –> CPU load graph
To navigate between specific parameters in monitoring charts, use the buttons
and
. To facilitate
visual identification, all charts have different colors.
–
TOTAL —
the total percentage of CPU load;
–
IO —
the percentage of CPU time spent on I/O operations;
–
IRQ —
the percentage of CPU time spent on hardware interrupts processing;
–
SIRQ —
the percentage of CPU time spent on software interrupts processing;
–
USR —
the percentage of CPU time used by user programs;
–
SYS —
the percentage of CPU time used by kernel processes;
–
NIC —
the percentage of CPU time used by programs with a changed priority.

SFP modules monitoring
This section contains status indication and optical line parameters.
Monitoring –> SFP modules
–
SFP port 0 status, SFP port 1 status —
optical module status:
miniGBIC presence
— module installation indication (module installed, module not in-
stalled);
Signal status —
indication of signal loss (signal lost, in operation);
Temperature, °C
— optical module temperature;
Voltage, V
— optical module power supply voltage, V;
TX bias current, mA
— bias current during transmission, mA;
Input power, mW —
signal power at reception, mW;
Output power, mW —
signal strength at transmission, mW.
4.1.2.4
Switch front port monitoring
The section displays information on the physical state of the switch ports: link availability, committed rate on
the port and transmission mode. If the port is a combo port (copper and optical connectors), the port number will
be marked "(SFP)". It disappears if the dual port is active and connected with a copper cable.
