19.9.6 Viewing Historic Data

The Scheduler page helps in generating reports for Analytics Dashboard from the older events that are stored in the Analytics Server database. This report is used only for generating graphs on Analytics Dashboard.

When you require to retrieve data from the database for a specific duration, the scheduler analyses the historic data, then generates a report for Analytics Dashboard.

To create report for historic data, you must use the scheduler page. This page helps with the following:

  • View the details of previously scheduled graphs.

  • Specify the time range, data availability (in days, after which the graphs will be auto deleted) for a new report for Analytics Dashboard.

  • Check the status of the report (scheduled, inprogress, completed).

  • Click on the completed analytic reports to view the graphs.

  • Delete the graphs.

To view the historic data, you must perform the following on Analytics dashboard:

  1. Click the scheduler icon to view the Analytics Scheduler screen.

  2. (Conditional) If you want scheduler to analyze the events that were generated during a specific duration, specify the following under Schedule New Analysis:

    • Time Range: Click to select the start and the end date of the historic data.

      Ensure that the specified time range is not duplicated or used in previous analysis. If the scheduler has already analyzed the data for a specific time, scheduling analysis for the same time will duplicate the data in the dashboard. For example, if you want to analyze events from 24-06-2017 to 29-7-2017 and under Analyzed Data Available, there is an existing data from 28-05-2017 to 22-7-2017. The data from 24-06-2017 to 22-7-2017 is same. To avoid duplicating the existing data, delete the older data.

    • Keep Data For: Click to select the period till when you want the report to be available under the Analysed Data Available list.

  3. (Conditional) If you have already scheduled analysis for generating reports, then to view the graphs, click the graph icon next to the report with Status as Completed under Analyzed Data Available.

    It may take some time for the scheduler to retrieve the data and analyze it for generating the report.

    NOTE:When you launch a dashboard with the historic data, you must not remove data filters under the Filtering tab. If the filter is removed, the graphs will not display the data for the time range that was specified.
