System view

Default Level

2: System level

Parameters

entry-number: Alarm entry index, in the range 1 to 65535.

alarm-variable: Alarm variable, a string of 1 to 256 characters, in dotted object identifier (OID) format, such as 1.3.6.1.2.1.2.1.10.1 (or ifInOctets.1). Only variables that can be parsed into INTEGER (INTEGER, Counter, Gauge, or Time Ticks) in the ASN.1 can be used for the alarm-variable argument.

sampling-interval: Sampling interval, in the range 5 to 65535 seconds.

absolute: Sets the sampling type to absolute.

delta: Sets the sampling type to delta.

threshold-value1: Rising threshold, in the range –2147483648 to +2147483647.

event-entry1: Index of the event triggered when the rising threshold is reached. It ranges from 0 to 65535.

threshold-value2: Falling threshold, in the range –2147483648 to +2147483647.

event-entry2: Index of the event triggered when the falling threshold is reached. It ranges from 1 to 65535.

owner text: Owner of the entry, a string of 1 to 127 characters. It is case sensitive and space is supported.

Description

Use the rmon alarm command to create an entry in the RMON alarm table.

Use the undo rmon alarm command to remove a specified entry from the RMON alarm table.

This command defines alarms. The generation and notification of an alarm however, is controlled by the event entry associated with it.

The following is how the system handles alarm entries:

1)         Samples the alarm variables at the specified interval.

2)         Compares the sampled values with the predefined threshold and does the following:

l           If the rising threshold is reached, triggers the event specified by the event-entry1 argument.

l           If the falling threshold is reached, triggers the event specified by the event-entry2 argument.

 

 

Examples

# Add entry 1 in the alarm table and sample the node 1.3.6.1.2.1.16.1.1.1.4.1 at a sampling interval of 10 seconds in absolute sampling type. Generate event 1 when the sampled value is greater than or equal to the rising threshold of 50, and event 2 when the sampled value is lower than or equal to the falling threshold of 5. Set the owner of the entry to user1.

Parameters

entry-number: Event entry index, in the range 1 to 65535.

description string: Event description, a string of 1 to 127 characters.

log: Logs the event when it occurs.

trap: Sends a trap when the event occurs.

trap-community: Network management station community to which traps are sent, a string of 1 to 127 characters.

log-trap: Performs both logging and trap sending when the event occurs.

log-trapcommunity: Community name of the network management station that receives trap messages, a string of 1 to 127 characters.

none: Performs no action when the event occurs.

owner text: Owner of the entry, a string of 1 to 127 characters. It is case sensitive and space is supported.

Description

Use the rmon event command to create an entry in the RMON event table.

Use the undo rmon event command to remove the specified entry from the RMON event table.

When an event is triggered by its associated alarm in the alarm table, the event group allows you to log it, send a trap, do both, or do neither at all. This helps control the generation and notification of events.

Description

Use the rmon prialarm command to create an entry in the private alarm table of RMON.

Use the undo rmon prialarm command to remove a private alarm entry from the private alarm table of RMON.

The following is how the system handles private alarm entries:

1)         Samples the private alarm variables in the private alarm formula at the specified sampling interval.

2)         Performs calculation on the sampled values with the formula.

3)         Compares the calculation result with the predefined thresholds and does the following:

l           If the rising threshold is reached, triggers the event specified by the event-entry1 argument.

l           If the falling threshold is reached, triggers the event specified by the event-entry2 argument.

 

 

Examples

# Create entry 5 in the private alarm table. Calculate the private alarm variables with the (1.3.6.1.2.1.16.1.1.1.6.1*100/.1.3.6.1.2.1.16.1.1.1.5.1) formula and sample the corresponding variables at intervals of 10 seconds to get the percentage of broadcasts received on GigabitEthernet 1/1/5 in the total packets. When this ratio reaches or is bigger than the rising threshold of 50, trigger event 1; when this ratio reaches or drops under the falling threshold, trigger event 2. Set the lifetime of the entry to forever and owner to user1.
