Using Monitor
You can monitor statistics in real time from the EDS-728’s web console and serial console.
Monitor by Switch
Access the Monitor by selecting “System” from the left selection bar. Monitor by System allows
the user to view a graph that shows the combined data transmission activity of all of the
EDS-728’s ports. Click on one of the four options—All Packets, TX Packets, RX Packets, or Error
Packets—to view transmission activity of specific types of packets. Recall that TX Packets are
packets sent out from the EDS-728, RX Packets are packets received from connected devices, and
Error Packets are packets that did not pass TCP/IP’s error checking algorithm. The All Packets
option displays a graph that combines TX, RX, and Error Packet activity. The four graphs (All
Packets, TX Packets, RX Packets, and Error Packets) have the same form, so we only show the All
Packets graph. The graph displays data transmission activity by showing
Packets/s
(i.e., packets
per second, or pps) versus
sec.
(seconds). In fact, three curves are displayed on the same graph:
Uni-cast
packets (in red color),
Multi-cast
packets (in green color), and
Broad-cast
packets (in
blue color). The graph is updated every few seconds, allowing the user to analyze data
transmission activity in real-time.
Monitor by Port
Access the Monitor by Port function by selecting
ALL Ports
or
Porti
, in which
i= 1, 2, …, 8
,
from the left pull-down list. The
Porti
options are identical to the Monitor by System function
discussed above, in that users can view graphs that show All Packets, TX Packets, RX Packets, or
Error Packets activity, but in this case, only for an individual port.
The
All Ports
option is
essentially a graphical display of the individual port activity that can be viewed with the Console
Monitor function discussed above. The All Ports option shows three vertical bars for each port.
The height of the bar represents
Packets/s
for the type of packet, at the instant the bar is being
viewed. That is, as time progresses, the height of the bar moves up or down so that the user can
view the change in the rate of packet transmission. The red colored bar shows
Uni-cast
packets,
the green colored bar shows
Multi-cast
packets, and the blue colored bar shows
Broad-cast
packets. The graph is updated every few seconds, allowing the user to analyze data transmission
activity in real-time.
