Description: HTTP hit not-modified service time
What is cacheHttpNmSvcTime?
Reports Squid's median service time for HTTP 'not-modified' hits, where a conditional request was validated against the origin without re-downloading the body. It's normally fast since only headers are exchanged, so a slowdown here suggests upstream validation requests are being delayed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.2.2.1.4 snmpwalk -v2c -c public <target> SQUID-MIB::cacheHttpNmSvcTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.2.2.1.4.1 snmpget -v2c -c public <target> SQUID-MIB::cacheHttpNmSvcTime.1
