Chapter 2 SNMP

To configure an SNMP alarm for the throughput rate by using the NetScaler command line

At the NetScaler command prompt, type the following commands to configure the SNMP alarm and verify the configuration:

wset snmp alarm PF-RL-RATE-THRESHOLD[-thresholdValue <positive_integer> [- normalValue <positive_integer>]] [-state ( ENABLED DISABLED )] [-severity <severity>] [-logging ( ENABLED DISABLED )]

wshow snmp alarm PF-RL-RATE-THRESHOLD

Example

>set snmp alarm PF-RL-RATE-THRESHOLD - thresholdValue 70 -normalValue 50

Done

>show snmp alarm PF-RL-RATE-THRESHOLD

Alarm		Alarm Threshold
Normal Threshold Time State			Severity
Logging		---------------
-----	----	---------------
----------------	----	--------	-------------
--------		70
1) PF-RL-RATE-THRESHOLD		70	-
50	N/A	DISABLED	-
ENABLED
Done

To modify or remove the threshold values by using the NetScaler command line

wTo modify the threshold values, type the set snmp alarm PF-RL-RATE-THRESHOLDcommand and the parameters to be changed, with their new values.

wTo remove the threshold values, type the unset snmp alarm PF-RL-RATE- THRESHOLD command, followed by the –thresholdValue parameter, but do not specify any value for the parameter.

Note: The normal-threshold value is automatically unset when you unset the high- threshold value.

To configure an SNMP alarm for PPS by using the NetScaler command line

At the NetScaler command prompt, type the following commands to configure the SNMP alarm for PPS and verify the configuration:

wset snmp alarm PF-RL-PPS-THRESHOLD[-thresholdValue <positive_integer> [- normalValue <positive_integer>]] [-state ( ENABLED DISABLED )] [-severity <severity>] [-logging ( ENABLED DISABLED )]
