Description
Octets
The total number of octets of data (including those in bad
packets) received on the network, excluding framing bits but
including FCS octets.
You can use this object as a reasonable estimate of Ethernet
utilization. If greater precision is desired, sample the Ethernet
statistic packet and octet objects before and after a common
interval. The differences in the sampled values are packets
(Pkts) and Octets, respectively, and the number of seconds in
the Interval. These values are used to calculate the utilization of
a 10 Mbps Ethernet port as follows:
Utilization =
The result of this equation is the utilization value, which is the
utilization percentage of the Ethernet segment on a scale of 0 to
100 percent.
Packets
The total number of received packets (including bad packets,
broadcast packets, and multicast packets).
Errors
The total number of errors that RMON received for this port.
Util%
The bandwidth utilization percentage of the Ethernet segment
on a scale of 0 to 100 percent.
The CSS can send notifications of RMON alarm events to a traplog file or a
configured log location, such as a log file on the CSS disk, a CSS session, a host
syslog daemon, or an e-mail address. The notification itself displays the time that
the event occurred, the event number, and its configured description in
parentheses.
For example:
FEB 15 15:41:22 EVENT#4 FIRED: (Service Toys exceeded 30,000
connections).
Pkts * (9.6 + 6.4) + (Octets * .8)
