Table 1-6 Handling alarm entries

Item	Handling
The sample value is greater than the upper limit threshold-value1.	Triggers the defined event event-entry1
The sample value is less than the lower limit threshold-value2.	Triggers the defined event event-entry2

 

Examples

# Create alarm group

l           Configure an event before configuring “alarm” and “prialarm”.

[H3C]rmon event 1 log  owner test-rmon

l           View configuration information.

l           Calculating the sample value using the defined extended alarm formula.

l           Comparing the sample values against the predefined threshold and take further actions (see Table 1-7).

Item	Handling
The calculated sample value is greater than the upper limit threshold-value1.	Triggers the defined event event-entry1
The calculated sample value is less than the lower limit threshold-value2.	Triggers the defined event event-entry2

# Add an extended alarm entry in the fifth line of the extended alarm table. Perform operation on the corresponding variant by means of the formula ((.1.3.6.1.4.1.43.45.1.6.1.2.1.1.2.1-.1.3.6.1.4.1.43.45.1.6.1.2.1.1.3.1)*100/.1.3.6.1.4.1.43.45.1.6.1.2.1.1.2.1) to get the port utilization of Gigabit Ethernet interface 1/1/1. Monitor the operation results at the sampling interval of 10 seconds. When the variation rate exceeds the upper threshold 50, trigger event 1; when the variation rate gets below the lower threshold 2, trigger event 2.
