RE: [SQU] Bandwidth Usage Notification

AFAIK squid can't do that. You could
a) use SNMP or the cachemgr to poll squid.
b) group all the requests into an unlimited delay pool and write some
additional code in squid to send an alert (perhaps an snmp trap?) when
added traffic spikes the delay pool past your threshold.
