The Windows NT Server and Windows NT Workstation Performance Monitor can be used to view many different TCP/IP-related counters. Because it accesses statistics that have been gathered by the SNMP service, the SNMP service must be installed on Windows NT-based computers where TCP/IP statistics are to be monitored. Performance Monitor counters are available for NIC, IP, ICMP, UDP, TCP, and NetBT.
One of the features of Performance Monitor is that it allows counters from various systems to be monitored from a single management window. It also supports setting alert levels for the counters being monitored.
