numBlocksAlloc
Module: MPIOS-MIB
OID (symbolic): MPIOS-MIB::numBlocksAlloc
OID (numeric): 1.3.6.1.4.1.5651.3.20.1.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of blocks of system memory that have been allocated in the system
What is numBlocksAlloc?
This reports the number of distinct memory blocks currently allocated across all tasks and system services on this device. A rising block count without a matching rise in numBytesAlloc's growth rate can point an admin toward many small allocations, sometimes symptomatic of a leak that allocates frequently but never frees.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5651.3.20.1.1.1.6 snmpwalk -v2c -c public <target> MPIOS-MIB::numBlocksAlloc
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5651.3.20.1.1.1.6.1 snmpget -v2c -c public <target> MPIOS-MIB::numBlocksAlloc.1
