Basics of managing widgets

The principle of data display in the widget depends on the type of the graph. The following graph types are available in KUMA:

• Pie chart ().
• Counter ().
• Table ().
• Bar chart ().
• Date Histogram ().
• Line chart

Basics of general widget management

The name of the widget is displayed in the upper left corner of the widgets. By clicking the link with the name of the widget about events, alerts, incidents, or active lists, you can go to the corresponding section of the KUMA web interface.

A list of tenants for which data is displayed is located under the widget name.

In the upper right corner of the widget, the period for which data is displayed on the widget is indicated (). You can view the start and end dates of the period and the time of the last update by hovering the mouse cursor over this icon.

The CSV button is located to the left of the period icon. You can download the data displayed on the widget in CSV format (UTF-8 encoding). The downloaded file name has the format <widget name>_<download date (YYYYMMDD)>_<download time (HHMMSS)>.CSV.

The widget displays data for the period selected in widget or layout settings only for the tenants that are selected in widget or layout settings.

Basics of managing "Pie chart" graphs

A pie chart is displayed under the list of tenants. You can left-click the selected segment of the diagram to go to the relevant section of the KUMA web interface. The data in that section is sorted in accordance with the filters and/or search query specified in the widget.

Under the period icon, you can see the number of events, active lists, assets, alerts, or incidents grouped by the selected criteria for the data display period.

Examples: In the Alerts by status widget, under the period icon, the number of alerts grouped by the New, Open, Assigned, or Escalated status is displayed. If you want to see the legend only for alerts with the Opened and Assigned status, you can clear the check boxes to the left of the New and Escalated statuses. In the Events widget, for which the SQL query SELECT count(ID) AS `metric`, Name AS `value` FROM `events` GROUP BY Name ORDER BY `metric` DESC LIMIT 10 is specified, 10 events are displayed below the period icon, grouped by name and sorted in descending order. If you want to view events with specific names in the legend, you can clear the check boxes to the left of the names of events that you do not want to see in the legend.

Basics of managing "Counter" graphs

Graphs of this type display the sum total of selected data.

Example: The Number of assets widget displays the total number of assets added to KUMA.

Basics of managing "Table" graphs

Graphs of this type display data in a table format.

Example: In the Events widget, for which the SQL query SELECT TenantID , Timestamp , Name , DeviceProduct , DeviceVendor FROM `events` LIMIT 10 is specified, displays an event table with TenantID, Timestamp, Name, DeviceProduct, and DeviceVendor columns. The table contains 10 rows.

Basics of managing "Bar chart" graphs

A bar chart is displayed below the list of tenants. You can left-click the selected diagram section to go to the Events section of the KUMA web interface. The data in that section is sorted in accordance with the filters and/or search query specified in the widget. To the right of the chart, the same data is represented as a table.

Example: In the a Netflow top internal IPs widget for which the SQL query SELECT sum(BytesIn) AS metric, DestinationAddress AS value FROM `events` WHERE (DeviceProduct = 'netflow' OR DeviceProduct = 'sflow') AND (inSubnet(DestinationAddress, '10.0.0.0/8') OR inSubnet(DestinationAddress, '172.16.0.0/12') OR inSubnet(DestinationAddress, '192.168.0.0/16')) GROUP BY DestinationAddress ORDER BY metric DESC LIMIT 10 is specified, the x-axis of the chart corresponds to the total traffic in bytes, and the y-axis corresponds to destination port addresses. The data is grouped by destination address in descending order of total traffic.

Basics of managing "Date Histogram" graphs

A date histogram is displayed below the list of tenants. You can left-click the selected section of the chart to go to the Events section of the KUMA web interface with the relevant data. The data in that section is sorted in accordance with the filters and/or search query specified in the widget. To the right of the chart, the same data is represented as a table.

Example: In the Events widget, for which the SQL query SELECT count(ID) AS `metric`, Timestamp AS `value` FROM `events` GROUP BY Timestamp ORDER BY `metric` DESC LIMIT 250 is specified, the x-axis of the diagram corresponds to event creation date, and the y-axis corresponds to the approximate number of events. Events are grouped by creation date in descending order.

Basics of managing "Line chart" graphs

A line chart is displayed below the list of tenants. You can left-click the selected section of the chart to go to the Events section of the KUMA web interface with the relevant data. The data in that section is sorted in accordance with the filters and/or search query specified in the widget. To the right of the chart, the same data is represented as a table.

Example: In the Events widget, for which the SQL query SELECT count(ID) AS `metric`, SourcePort AS `value` FROM `events` GROUP BY SourcePort ORDER BY `value` ASC LIMIT 250 is specified, the x-axis corresponds to the approximate port number, and the y-axis corresponds to the number of events. The data is grouped by port number in ascending order.
