In other words, it can be acquired programmatically.) I'd like to include the value of this log verbosity level variable within the stream of forwarded data, so that I can search against it like I would search against punct or host or sourcetype or what-have-you. (The verbosity level IS ONLY available in a registry key or in a text file, depending on the OS. Unfortunately, the application does NOT write the verbosity level within the log stream that it generates. Here's a specific example: I am monitoring an application that allows for a wide range of log verbosity levels. I would like to "inject data" into the stream of forwarded events that would be made available either by a search-time extraction or injected directly into the log stream as an indexed field.
