Description: HTTP refresh hit service time
What is cacheHttpNhSvcTime?
Reports Squid's median service time for HTTP 'refresh hit' requests, where a stale cached object was revalidated and confirmed still fresh. A rising value points to slow revalidation round-trips to the origin server rather than a caching problem per se.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.2.2.1.11 snmpwalk -v2c -c public <target> SQUID-MIB::cacheHttpNhSvcTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.2.2.1.11.1 snmpget -v2c -c public <target> SQUID-MIB::cacheHttpNhSvcTime.1
