Viewing an Analytics Report

The Analytics page lets you view predefined or customized analytics reports, and also create customized reports.

An analytics report displays data according to which object(s), such as the cluster, a particular CNode or view, and which properties, for example bandwidth or patency, are selected in the report definition. For each object included in the report, a separate graph is displayed.

Each report has a default time resolution and timeframe, although these can be changed while viewing.

  1. From the left navigation menu, select Analytics -> Analytics. 

  2. Select a report from the Predefined Analytics list or the Customized Analytics list. 

    • Use the search box to find a report by name.

    • Use filters to filter the list of reports.

  3. Once the report is displayed, you can:

    • Set a custom Time Resolution:

      • Seconds to show raw data, which is polled every ten seconds.

      • Minutes to show data aggregated to five minute granularity.

      • Hours to show data aggregated to one hour granularity.

      • Days to show data aggregated to one day granularity.

    • Change the displayed timeframe in the Defined Time field. Choose from one of the available timeframes (10m, 2h, and so on). These vary depending on the time resolution, since data with lower granularity is stored for longer. (See How far back is data available?)

    • Zoom in, by clicking and dragging over part of the graph.

    • Change the period of time shown in the graph. Click time_period.png to change the specific period of time shown in the graph. By default, the graph shows the most recent data, with the timeframe ending at the present time.

    • Select an Aggregation Type to change the aggregation function you are viewing. This is relevant and available if you are viewing aggregated data samples, since several aggregation functions are calculated and you can choose which one to display. Note that if the time resolution is set to seconds, the data samples are raw and therefore aggregation type is not available.

    • Display a graph for a particular object by choosing the object name from the Select Object dropdown.

    • Set Intersampling Status to On to display the deltas between each value and the previous one, instead of the values themselves.

    • Use Sync Y to control synchronization of Y axis scaling across multiple graphs displayed on the page. If enabled (default), all graphs are shown with the same maximum and minimum possible values on their Y axis. If disabled, each graph has its own scaling of the Y axis.

 

Customized Analytics Reports

If the report you want to see doesn't exist, it's easy to create a new one.

Creating a Customized Report

  1. In the left navigation menu, choose Analytics -> Analytics.

  2. On the Analytics page, do one of the following:

    • Under Predefined Analytics, select a predefined report that is similar to the one you want to create and click copy_report.png to copy it. 

      OR

    • Click add_button.png under Customized Analytics to create an analytics report from scratch.

  3. In the Copy Analytics or Create Analytics dialog that opens, edit or enter the details:

    Field

    Description

    Name

    Enter a name for the report.

    Time Resolution

    Set the default time resolution for the report:

    • Seconds to show raw data, which is polled every ten seconds.

    • Minutes to show data aggregated to five minute granularity.

    • Hours to show data aggregated to one hour granularity.

    • Days to show data aggregated to one day granularity.

    This time resolution is used when a user opens the report. The user can change the time resolution while viewing.

    Timeframe

    Set the default timeframe for the report.

    The timeframe determines the period of time over which data is displayed.

    This timeframe is used when a user opens the report. The user can change the timeframe while viewing.

    Object Type

    Select the type of the object(s) to report metrics for:

    • Cluster to view metrics for the whole VAST cluster.

    • CNode to view metrics for one or more CNodes.

    • View to view metrics for one or more VAST Element Store views.

    • ReplicationStream to view metrics for one or more protected paths.

    You'll further specify the object(s) in the Objects field.

    Objects

    Select one or more objects to report metrics for.

    Each object's data are displayed on a separate graph.

    If no object is selected, all existing and future objects of the selected Object Type are included in the report.

    Selected Properties and Available Properties

    Select one or more properties (metrics) to include in the report under Available Properties and click the left arrow to move them to Selected Properties.

    Each selected property is shown in a different color on the graph(s). 

  4. Click Create. 

    The report is created, and opened for you.

  2. Under Customized Analytics , select the report that you want to edit and click edit_report_button.png.

  2. Under Customized Analytics , select the report that you want to delete and click delete_report_button.png.
