Preserving Data

Last Modified: August 30, 2021

Set exceptions to data-aging rules to retain data anomalies you want to view in the future.

InsightCM automatically deletes historical data when specified conditions are met if administrators set data-aging strategies. Aging conserves space on the server, but you may want to ensure data from a specific acquisition remains available for viewing. Preserve data by marking the file for retention.

Complete the following steps to have the server retain data associated with a specific acquisition:

  1. Click the Data Viewer button to navigate to the Data Viewer page.
  2. Expand the equipment and sensor for which you want to set an exception and select a feature.
  3. Move the cursor to the point of interest in the Trend viewer and double-click it.
  4. Complete the following step according to the current workspace mode:
    1. (Periodic Data mode): Click the Trend viewer Action menu»Data Events and select Retain Data Event. The Data Viewer page identifies the sensor and acquisition to be retained and also prompts you to enter an optional comment that the server will store with the data.
    2. (Stream Data mode): Click the Trend viewer Action menu»Data Events and select Retain Stream. The feature and sensor data remains accessible whenever the Trend viewer time-axis contains the time at which the acquisition occurred.
    The server will retain all data associated with the sensor acquisition, not just the trend value or curve that was active when you clicked the Retain Data Event button. Retaining data means you have access to feature values, the time waveform, and other measurements, such as the FFT curve.
  5. To export a TDMS file for a data event, click Action menu»Data Events.
  6. Select Export Data Event and open the downloaded file.
