Downloading Performance Data Samples
To create models using TCM, the sample performance data must be collected from the NonStop
host system using Measure and formatted by MeasTCM. Once the sample performance data has
been summarized by MeasTCM in a CSV file, you need to download it from the host to the
workstation and load it into TCM.
To download performance data samples to the PC, follow the download procedure you normally
use in Windows. All CSV files for the same application or set of applications should be kept in the
same folder. TCM detects any truncated data and issues an error message.
NOTE: All CSV files must have the extension .CSV.
Finding Product Version Information
You can use the Excel macro VPROC.XLM to get the product version of any TCM file. VPROC.XLM
is included in your TCM folder.
To find product version information:
1. Run VPROC.XLM.
2. Enter the name of the file.
3. VPROC responds with the product version of TCM.
4. Click OK button.
