Description: Highest file descriptors in use
What is cacheCurrentFileDescrMax?
Reports the highest number of file descriptors Squid is configured/able to use. An admin raising this (along with the OS-level ulimit) is the usual fix for a busy proxy that's hitting 'too many open files' errors.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.1.13 snmpwalk -v2c -c public <target> SQUID-MIB::cacheCurrentFileDescrMax
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3495.1.3.1.13.1 snmpget -v2c -c public <target> SQUID-MIB::cacheCurrentFileDescrMax.1
