Description: &Configured critical threshold from which the active critical threshold is derived for the size of associated shared memory segment monitoring of the shared memory watcher. The threshold can be specified as either an absolute value (n) or a percentage (n%). It can also be specified as the absolute value left free (nF). The value of uxsA2StatusSHMSegSzTotal will be the reference value for n% and nF notations.

What is uxsA2StatusSHMSegSzCrit?

Configures the critical threshold (as an absolute value or percentage) used to determine when the size of the monitored shared memory segment should be flagged as critical.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.791.2.10.2.74.2.16.2.1.21
snmpwalk -v2c -c public <target> CAIUXSA2-MIB::uxsA2StatusSHMSegSzCrit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.791.2.10.2.74.2.16.2.1.21.1
snmpget -v2c -c public <target> CAIUXSA2-MIB::uxsA2StatusSHMSegSzCrit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.791.2.10.2.74.2.16.2.1.21.1 s <value>
