succeeded or failed and how much time it took. It has information in a short/simple format and since
there is not much data per request, the file has more data in terms of amount of time.

node, grep for the IP address as the keyword in cwmftp.log and cwmftpd.request_log.
When OOEMC sends FTP requests, it also sends the nodeId along with the request as part of the
destination file. This nodeId is used to retrieve the ftp user/password from the node_info table. This can
be used for user/password validation.
