Anomaly Detections Report window

When changes are made to the Anomaly Detection report configuration, the report window is updated with the new report data.

Report access permissions

In the Report Access Permissions window, you can select the users and groups who can view and edit the current report. To configure access, select the appropriate user groups in the left or right panel and click Save.

You can configure the administrators of the report by available user group. Report administrators have all of the permissions available to specified users of the report. Report administrators can edit and delete the report. Members of the Admin group are administrators for all reports in the system.

You can configure the users of the report by available user group. Report users can see the report, change parameters, export it, and save it under a new name. You can also change anomaly report access permissions through the Report Manager.

Report Schedules

You can schedule the execution of the report on a daily, weekly, or monthly basis for delivery to selected users in PDF or Excel format. To configure and deliver report snapshots from the Portal, you must enter a valid email address for your user account. To schedule a report execution, click the Schedule Report icon in the toolbar. The General tab of the Report Manager is displayed.

Data shown

To force a refresh of the report window, click the Refresh icon in the toolbar. If you are not seeing data for your Anomaly Detections, more configuration can be required.

In the report, each anomaly is represented by vertical bars of a different color, showing the deviation values of each anomaly for each time period. Anomalies can be displayed across a range of multiple dates.

Each bar indicates the standard deviation for the values for a date, which is based on data over the rolling window. You can display hourly or daily data in a report, but not both:

Daily anomalies: Report indicates change as a percentage between the focus date and the data for the anomaly in the rolling window.
Hourly anomalies: Report indicates change as a percentage between the displayed hour of the focus date and the data for the anomaly in the rolling window.

Anomaly Detections are sorted for display that is based on the count of standard deviations and are colored based on that order. When a new Anomaly Detection is added to an existing chart, color coding for each anomaly can change.

For each type of anomaly, the data in the rolling window depends on the configured calculation mode.

Export

To export a displayed scorecard, click the Export icon in the toolbar and select the type of export:

Select the report format: PDF or Excel.
Enter an optional message.
Enter recipient email addresses or aliases, which are separated by commas.
To send the report, click Send. The report is exported in the selected format and emailed to the specified list of addresses.

Calculation Mode

Just below the X-axis of the chart, you can review the calculation mode that is used for the Anomaly Detections in the report.

For each calculation mode, a different statement is displayed. In the following examples, the minimum number of data points is configured to be 4 and the maximum number of data points is 16. These values are the default values. The minimum and maximum values can be configured by parameter.

Calculation Mode: Report Statement
Consecutive Days: Anomaly Detections based on data from 4 to 16 data points (consecutive days)
Same Days: Anomaly Detections based on data from 4 to 16 data points (same day of week)

Chart Description

Below the chart, you can enter a description of the chart, which is also displayed in exported versions.

To enter a chart description, click the text box below the chart. Enter your description and click Apply. To save the changes to your chart, click the Save icon in the toolbar.

Anomaly Detail Table

Details of the report are displayed in a table below the graph. You cannot sort by the name of the anomaly. To arrange the grid in a specific order, add the anomalies to the report in the wanted order. To resize the width of a column, click and drag the right border of the column header. If any column contains the value --, there is insufficient data to complete the anomaly calculation.

Column

Description

Date

Date stamp for anomaly data. For hourly anomalies, each row represents a different hour of the day.

Threshold

If thresholding is applied to the visual chart, a blue dot indicates the row values that are outside the defined threshold.

Anomaly

Name of the anomaly.

Click the Anomaly Detection name link to drill down on the data.

Std Dev Count

Number of deviations is the difference between focus period's count minus the average of the previous set of data points. The formula:


(Current count - avg of prev X data points) /
 (Standard deviation of prev X data points)

Focus

Count of instances during the focus period.

DoD%

Change in counts between the previous week's day and the focus date, as a percentage of the previous week's day.

HoH%

Change in counts between the previous week's hour and the displayed hour for the focus date, as a percentage of the previous week's hour.

Weekly Avg or Daily Avg

The average of values over the rolling window, depending on the calculation mode.

This calculation is based on the minimum and maximum values to use in the calculation.

Std Dev

Calculation of the standard deviation

Anomaly drill-down

You can drill-down on each anomaly in the report to reveal the base reporting data from which the deviations were calculated. Depending on the type of anomaly, a different type of report is displayed in the Discover Report Builder:

Anomaly Type: Report Type
event: Event report for the focus day
dimension: Report with the selected dimension as the Y-axis. The X-axis is populated by the Day dimension if the source is a Daily anomaly or Hour of Day dimension, or if the source is an Hourly anomaly.
ratio: Report with the selected ratio for the focus day and the ratio with the dimension and segment value as whitelisted values.

Adding Reports to Dashboards

You can add the currently displayed report to a dashboard. To add it, click the Add Report to Dashboard icon in the toolbar. The Add Report to Dashboard dialog is displayed. You can add reports to dashboards to which you have access. You can add report charts to dashboards only if the report can be charted.

Property

Description

Title

You can edit the title that is displayed in the dashboard without changing the title to the report.

Size

Define the size of the report as it is displayed in the dashboard. These values are grid blocks, which are reflected in the image to the right of the sizing parameters.

Color

Specify the base color of the report.

Updates

You can configure how frequently the dashboard report queries for updated information from the saved report.

There is no use in configuring updates to happen more frequently than once per hour or once per day, depending on the type of Anomaly Detections in the report.
Note: If the report that you are adding to the dashboard references data from completed sessions only, configuring an update interval to be more frequent than the interval at which the data collection process is run is not useful. By default, data collection occurs every 5 minutes; in this case, report updates must not occur more frequently than a 5 minute interval for reports that contain completed session data only. If the report references data from active sessions, you can set the update interval to be more frequent than every 5 minutes. Depending on the configured report and the number of reports in the dashboard, there can be performance impacts.

Hour

For hourly anomaly detections, you can select the hour of the selected date to report in the dashboard component. The All Hours selection displays all hours of the selected day.

Period

For anomaly detections, you can select the period of the selected date to report in the dashboard component. You can choose to update the report daily, weekly, monthly, or quarterly.

Display

Select the component of the report to display in the dashboard: Chart or Table. You can add both as separate components to the same dashboard.

Drilldown

When Enabled, dashboard users can drill into the dashboard data to review the underlying report.

Target Tab

To select the dashboard and its tab to which to add the report, click Select a Tab. Select the dashboard and tab to which to add the report.
