With IPHost Network Monitor you can run WMI Keep Alive Time monitoring of various devices in your network.
To create a WMI monitor for Keep Alive Time, provide host name (it must be a Windows host) and specify custom WQL query:
The KeepAliveTime property indicates how often the TCP attempts to verify that an idle connection is still intact by sending a Keep Alive Packet. A remote system that is reachable will acknowledge the keep alive transmission. Keep Alive packets are not sent by default. This feature may be enabled in a connection by an application. Default: 7,200,000 (two hours)
The Win32_NetworkAdapterConfiguration class represents the attributes and behaviors of a network adapter. This class has been extended to include extra properties and methods that support the management of the TCP/IP and Internetworking Packet Exchange (IPX) protocols (and are independent of the network adapter).
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.
