cpqOsMemCacheFaultsPerSec
Module: CPQOS-MIB
OID (symbolic): CPQOS-MIB::cpqOsMemCacheFaultsPerSec
OID (numeric): 1.3.6.1.4.1.232.19.2.4.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Cache Faults/sec is the number of faults which occur when a page sought in the file system cache is not found there and must be retrieved from elsewhere in memory (a soft fault) or from disk (a hard fault). The file system cache is an area of physical memory that stores recently used pages of data for applications. Cache activity is a reliable indicator of most application I/O operations. This counter counts the number of faults, without regard for the number of pages faulted in each operation.
What is cpqOsMemCacheFaultsPerSec?
This read-only integer reports the number of faults occurring when a page sought in the file-system cache isn't found there and must be retrieved from elsewhere in memory or from disk, serving as a reliable indicator of application I/O activity. An admin watches this to gauge how effectively the file-system cache is serving application requests. For example, a rising cpqOsMemCacheFaultsPerSec could indicate the working set of files being accessed has outgrown the available cache.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.19.2.4.7 snmpwalk -v2c -c public <target> CPQOS-MIB::cpqOsMemCacheFaultsPerSec
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.19.2.4.7.1 snmpget -v2c -c public <target> CPQOS-MIB::cpqOsMemCacheFaultsPerSec.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cpqOsMemCacheFaultsPerSec.1
