cermPolicyFallingThreshold
Module: CISCO-ERM-MIB
OID (symbolic): CISCO-ERM-MIB::cermPolicyFallingThreshold
OID (numeric): 1.3.6.1.4.1.9.9.510.1.3.2.1.9
Node type: OBJECT-TYPE
Type: CermThresholdOrZero
Access: read-write
Description: This object indicates the falling threshold value set for the threshold configuration.
Lets assume that system global threshold value (in percentage) for 'io' memory resource owner is set to 10% as minor falling threshold value, 20% as major falling threshold value and 30% as critical falling threshold value. When the total 'io' memory utilization falls below 10%, a minor 'down' notification will be sent to relevant resource user(s). When the total 'io' memory utilization falls below 20%, a major 'down' notification will be sent to relevant resource user(s). When it falls below 30%, a critical 'down' notification will be sent to relevant resource user(s). The 'down' notification will be sent only if corresponding 'up' notification has already been sent to relevant resource user(s).
Zero value for this object indicates that the falling threshold value is not configured.
What is cermPolicyFallingThreshold?
This is the falling threshold percentage in this policy entry, and per the MIB's example, io memory might use 10 percent as the minor falling threshold, 20 percent as major, and 30 percent as critical, each requiring its own policy entry. The falling threshold only becomes relevant after the corresponding rising threshold has already been crossed and an up notification sent, so this value defines how far usage has to actually recede before ERM will consider that specific severity tier's condition cleared. Per the example, if io memory utilization crossed the 60 percent minor rising threshold and climbed further, it would need to drop all the way down to 10 percent, not just below 60 percent, before ERM sends the minor-tier down notification.
