expResourceDeltaWildcardInstanceMaximum
Module: DISMAN-EXPRESSION-MIB
OID (symbolic): DISMAN-EXPRESSION-MIB::expResourceDeltaWildcardInstanceMaximum
OID (numeric): 1.3.6.1.2.1.90.1.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: For every instance of a deltaValue object, one dynamic instance entry is needed for holding the instance value from the previous sample, i.e. to maintain state.
This object limits maximum number of dynamic instance entries this system will support for wildcarded delta objects in expressions. For a given delta expression, the number of dynamic instances is the number of values that meet all criteria to exist times the number of delta values in the expression.
A value of 0 indicates no preset limit, that is, the limit is dynamic based on system operation and resources.
Unless explicitly resource limited, a system's value for this object should be 0.
Changing this value will not eliminate or inhibit existing delta wildcard instance objects but will prevent the creation of more such objects.
An attempt to allocate beyond the limit results in expErrorCode being tooManyWildcardValues for that evaluation attempt.
What is expResourceDeltaWildcardInstanceMaximum?
Caps how many dynamic per-instance delta-tracking entries the device will maintain for wildcarded delta expressions; 0 (the default) means no preset limit, and exceeding a nonzero cap causes new evaluations to fail with a tooManyWildcardValues error instead of silently consuming unbounded memory.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.90.1.1.2 snmpwalk -v2c -c public <target> DISMAN-EXPRESSION-MIB::expResourceDeltaWildcardInstanceMaximum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.90.1.1.2.1 snmpget -v2c -c public <target> DISMAN-EXPRESSION-MIB::expResourceDeltaWildcardInstanceMaximum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.90.1.1.2.1 i <value>
