Use a capture trigger to automate actions to follow the capture. A trigger is a set of conditions that, when met, initiate an action. For example, before using Network Monitor to capture data from the network, you can set a trigger to stop the capture or to run a program or command file. You can also specify the conditions under which these actions will occur. One example of a trigger is a pattern match. You can save a trigger to the local computer if you save a capture filter. The default file path for saving filters is the \System32\Netmon\Captures directory in the root directory.
