Description: Available number of file descriptors
What is cacheCurrentUnusedFDescrCnt?
Reports how many file descriptors are currently available (unused) to the Squid process. An admin watches this on a busy proxy to catch it approaching zero before Squid starts refusing new connections for lack of descriptors.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.1.10 snmpwalk -v2c -c public <target> SQUID-MIB::cacheCurrentUnusedFDescrCnt
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.1.10.1 snmpget -v2c -c public <target> SQUID-MIB::cacheCurrentUnusedFDescrCnt.1
