Preserving Data from Aging Strategies

Last Modified: August 30, 2021

Ensure data from a specific acquisition remains available for viewing regardless of aging rules.

Before you begin, you need to have acquired data.

Feature and sensor data remains accessible whenever the Trend viewer time-axis contains the time at which the acquisition occurred. When you choose to retain data, InsightCM retains all the data associated with the sensor acquisition, such as feature values, the time waveform, and other measurements, such as the FFT curve.

Complete the following steps to identify which data events you want to retain.
  1. Click the Navigation menu »System»Data Events.
  2. In the Data Events dialog, select an equipment from the asset tree to bring up a corresponding log data events on the right.
  3. Select the data event of interest that contains data sets.
  4. Click Retain.

    Remove the retain property by selecting a data event marked for retention and clicking Retain.

  5. Click OK.
  6. Verify that the data event that been marked for retention.

    Click the Action menu above the data events log and select Export to export a TDMS file for a data event.

You have assigned a retain property to a data event to preserve it from deletion due to aging strategies.
For example, if you observe an anomaly or value of interest and want to ensure that you and others can view the data for a longer period of time than the aging strategy allows, you want to assign a retain property to that data event.
