With IPHost Network Monitor you can run WMI Connection Failures monitoring of various devices in your network.
To create a WMI monitor for Connection Failures, provide host name (it must be a Windows host) and specify custom WQL query:
Connection Failures is the number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
The TCP performance object consists of counters that measure the rates at which TCP Segments are sent and received by using the TCP protocol. It includes counters that monitor the number of TCP connections in each TCP connection state.
IPHost Network Monitor is an advanced and easy tool for monitoring LAN and WAN networks, network servers, workstations and TCP/IP devices. Use IPHost Network Monitor to monitor your servers, domains, computers and devices.
