Private alarm group
The private alarm group calculates the values of alarm variables and compares the result with the defined
threshold, realizing a more comprehensive alarm function.
The system handles the prialarm alarm table entry—as defined by the user—in the following ways:
• Periodically samples the prialarm alarm variables defined in the prialarm formula.
• Calculates the sampled values based on the prialarm formula.
• Generates an appropriate event if the threshold value is reached.
NOTE:
If an alarm entry crosses a threshold multiple times in succession, the RMON agent generates an alarm
event only for the first crossing. For example, if
the value of a sampled alarm variable crosses the risin
g
threshold multiple times before it crosses the fallin
g
threshold, only the first crossin
g
tri
gg
ers a risin
g
alarm
event. If the count result of the private alarm group overpasses the same threshold multiple times, only the
first one can cause an alarm event. In other words, the rising alarm and falling alarm are alternate.
Configuring the RMON statistics function
The RMON statistics function can be implemented by either the Ethernet statistics group or the history
group, but the objects of the statistics are different. You can configure a statistics group or a history group.
• A statistics object of the Ethernet statistics group is a variable defined in the Ethernet statistics table,
and the recorded content is a cumulative sum of the variable from the time the statistics entry is
created to the current time. For more information, see Configuring the RMON Ethernet statistics
function.
• A statistics object of the history group is the variable defined in the history record table, and the
recorded content is a cumulative sum of the variable in each period. For more information, see
Configuring the RMON history statistics function.
Configuring the RMON Ethernet statistics function
Follow these steps to configure the RMON Ethernet statistics function:
To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet interface view interface interface-type interface-number —
Create an entry in the RMON
statistics table
rmon statistics entry-number [ owner text ] Required
NOTE:
You can create one statistics entry per interface and up to 100 statistics entries on the device. When the
number of statistics entries exceeds 100, you cannot add new entries.
Configuring the RMON history statistics function
Follow these steps to configure the RMON history statistics function:
