Description: Count of attempts on file header cache.
What is vmsFileFileHdrAttempt?
This is a count of attempts made against the file header cache, i.e., all file header lookups regardless of whether they were cache hits. An administrator pairs this with vmsFileFileHdrHit to derive the cache's hit ratio for file-open activity. For example, a spike in vmsFileFileHdrAttempt coinciding with slower file-open times would suggest the file header cache is being thrashed by too many distinct files being opened.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.597.4.15.2.8 snmpwalk -v2c -c public <target> COMTEK-VMS-NM-SYSMGR-MIB::vmsFileFileHdrAttempt
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.597.4.15.2.8.1 snmpget -v2c -c public <target> COMTEK-VMS-NM-SYSMGR-MIB::vmsFileFileHdrAttempt.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> vmsFileFileHdrAttempt.1
