The MDEX Engine request log (also called the Dgraph request log) is the file that captures Web application query information.
The MDEX Engine always generates a request log with a default name
dgraph.reqlog. You use the
--log option when running the MDEX Engine to specify a
different path to store the request log.
You can extract queries from this log file and use them with the Eneperf tool to analyze Web application performance. You can also use Perl to extract useful information from Dgraph request logs.
In addition, depending upon the size of your log files, you can import them into a tool that allows you to manipulate column-based data, such as Microsoft Excel.
