This is relevant only for the duration of the test. At the end of the test, the file is removed from the merkyl tracker. Note that this is a blocking call, ie, we ensure that the file is being logged by merkyl, before we continue. This is important and prevents the file_add operation being queued and processes which generate log information activating before the log is being monitored. This is achieved using the grab_result switch, but in fact, nothing will be received. It is worth noting that the file path must be "discoverable" by merkyl. This may mean editing the allowed_files prior to deploying merkyl. Args: log_name: Full path to the log file wishing to be monitored.
