expResourceDeltaMinimum
Module: DISMAN-EXPRESSION-MIB
OID (symbolic): DISMAN-EXPRESSION-MIB::expResourceDeltaMinimum
OID (numeric): 1.3.6.1.2.1.90.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The minimum expExpressionDeltaInterval this system will accept. A system may use the larger values of this minimum to lessen the impact of constantly computing deltas. For larger delta sampling intervals the system samples less often and suffers less overhead. This object provides a way to enforce such lower overhead for all expressions created after it is set.
The value -1 indicates that expResourceDeltaMinimum is irrelevant as the system will not accept 'deltaValue' as a value for expObjectSampleType.
Unless explicitly resource limited, a system's value for this object should be 1, allowing as small as a 1 second interval for ongoing delta sampling.
Changing this value will not invalidate an existing setting of expObjectSampleType.
What is expResourceDeltaMinimum?
Sets the shortest delta-sampling interval, in seconds, the device will accept for any expression using deltaValue sampling; raising it from the default of 1 second reduces the constant-computation overhead of tracking deltas, while -1 means the device refuses deltaValue sampling altogether.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.90.1.1.1 snmpwalk -v2c -c public <target> DISMAN-EXPRESSION-MIB::expResourceDeltaMinimum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.90.1.1.1.1 snmpget -v2c -c public <target> DISMAN-EXPRESSION-MIB::expResourceDeltaMinimum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.90.1.1.1.1 i <value>
