cufwUrlfNumServerTimeouts

Module: CISCO-UNIFIED-FIREWALL-MIB

OID (symbolic): CISCO-UNIFIED-FIREWALL-MIB::cufwUrlfNumServerTimeouts

OID (numeric): 1.3.6.1.4.1.9.9.491.1.3.1.16

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The number of times the firewall failed to receive a response from the configured URL filtering servers for a request to authorize a URL access request.

This is equal to the number of times a firewall removed a URL access request from the queue of pending requests because no response was received from the URL filtering server(s).

This value is accumulated from the last reboot of the firewall.

What is cufwUrlfNumServerTimeouts?

This Counter64 counts the number of times the firewall failed to get a response from any configured URL filtering server for a URL authorization request, which equals the number of times a request was pulled from the pending queue with no server answer, accumulated since the last reboot. An admin uses this to judge how reliably the URL filtering servers are responding overall. A rising count here alongside stable network conditions would point to a problem with the filtering servers themselves rather than the network path to them.
