Private alarm group
The private alarm group calculates the values of alarm variables and compares the results with the
defined threshold for a more comprehensive alarming function.
The system handles the private alarm entry (as defined by the user) in the following ways:
Periodically samples the private alarm variables defined in the private alarm formula.
•
• Calculates the sampled values based on the private alarm formula.
Compares the result with the defined threshold and generates an appropriate event if the threshold
•
value is reached.
If a private 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
rising threshold multiple times before it crosses the falling threshold, only the first crossing triggers a rising
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, as follows:
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
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

Configuring the RMON Ethernet statistics function

Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Create an entry in the
RMON statistics table.
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 guidelines when you configure the RMON history statistics function:
The entry-number for an RMON history control entry must be globally unique. If an entry number
•
has been used on one interface, it cannot be used on another.
