Module: SQUID-MIB
OID (symbolic): SQUID-MIB::cacheBlockingGetHostByAddr

Node type: OBJECT-TYPE

Access: read-only
Description: Number of blocking gethostbyaddr requests
What is cacheBlockingGetHostByAddr?
Counts how many times Squid had to perform a blocking (synchronous) gethostbyaddr call instead of its normal asynchronous reverse-DNS path. Like cacheBlockingGetHostByName, a growing count is worth investigating since blocking calls can stall the proxy's request handling.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3495.1.4.2.7 snmpwalk -v2c -c public <target> SQUID-MIB::cacheBlockingGetHostByAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3495.1.4.2.7.1 snmpget -v2c -c public <target> SQUID-MIB::cacheBlockingGetHostByAddr.1
