Silk Performer offers a command-line tool (csv2tsd.exe) that enables you to convert .csv files (comma-separated values) into .tsd files (time series data).
Converting data to the .tsd format is useful when you monitor external Windows data that, for security reasons, cannot be monitored by Silk Performer. By converting .csv data into the .tsd format, external data can be analyzed alongside internal Silk Performer monitoring data within Performance Explorer.
For example, if a performance counter measures the behavior of a remote server and the results of that monitor are saved in .csv files, those results can be imported into Performance Explorer for analysis alongside the results of a Silk Performer load test involving the same server. Using Silk Performer, you then have the opportunity to look for correlations between the two data sets.
