Home area
Overview
The Home area provides a quick, real-time overview of event activity, alerts, and statistics. The event data details are saved with a long history that can always be accessed if needed. The Home area also contains several widgets apart from the account statistical information.
Read the following sections to learn more about each of the widgets in the Home area:
Last 5 Unread Alerts
See the last 5 triggered alerts in your domain. Hover over an alert and click the View alerts details button to expand a menu that shows the details of the alert. Click the eye button to mark the alert as closed and delete it from this list.
The color of the lighting icon at the left of each alert indicates the priority assigned to it. See the color legend at the bottom of the widget.
Number of Events
Check the total number of events received every hour, minute... (Period field) over the range specified in the Time Range field. Click the refresh icon to update the widget each time you modify the settings. Hover over the line to see the specific event count and date.
Click and drag the mouse on the chart to zoom to the selected area. Select Reset zoom to go back to the default view.
Event Volume
This column chart plots the total size of the events received over time along with the size of the associated indexed data*. By default, it displays the volume of ingested per day over the last 30 days. Use the Time Range and Period pickers to select a different time period and granularity, then click the refresh button to apply it. You can also click and drag over an area of the chart to zoom. Select Reset zoom to go back to the previous setting.
Hover over a column to display a tooltip summarizing information about that time period.
Click Index or Data under the chart to show or hide that type of data (they are both activated by default). The horizontal broken line indicates the data volume average over the selected time range for each data type activated, together with a text box indicating the average volume in numbers.
* Indexed data is aggregated every 24 hours and is therefore not plotted when the Period is set to a unit of less than 1 day.
Events by Technology
This Voronoi widget represents the number of events received and its size for every type and technology. Use the Time Range and Value fields to select the period you want to analyze and the values you want to get. Click the refresh icon to update the widget each time you modify the settings.
Drag and drop the grouping keys to change the cell distribution, and hover over each cell to see the amount/size of events and its percentage. See Voronoi treemap for tips and additional information on using a Voronoi widget.
Total Daily Volume
This heat map calendar represents the daily volume ingested and added to indexes in your Devo domain over the last 12 months. Hover over a column to display a tooltip summarizing the total volume ingested that day. The color scale is calculated dynamically using the lowest and highest sizes in the year as reference values.
Live Event Stats
Gauge meters indicating the current average levels of ingestion in terms of events per second and data volume per second. The gauges are color-coded with green, yellow, and red to indicate how current ingest levels compare to the maximum levels over a recent period. The percentages inside each gauge indicate where the current average value sits as compared to the recent minimum and maximum values. For example, 90% indicates that the current level is close to the recent maximum, 10% indicates a current level closer to the recent minimum, and 50% indicates that the current value sits between the minimum and maximum values.
Use the variable time period selectors to modify the periods compared, then click the refresh button to apply it.
Top 10 (Last 24h)
Select the table names in the Event Source column to open them. Click one of the sparkline charts next to them to open the Data source stats chart.
You will see a dynamic chart that displays the number of events received over a specific period of time. Plus, it analyzes previous periods of time and predicts future trends. The white line indicates the number of events received over the period of time indicated. The green band represents the average amount of data received in the past.
The following table describes the settings you can configure to visualize different sets of information.
Click the refresh icon to update the contents of the chart each time you change the setting options.
| Time buttons | Select a time period to analyze. You can represent data received over the last day, last week, last month or last year. |
|---|---|
| Predict data | Select this option to forecast the amount of events that the table will receive over the following day, week, month or year. The graph displays the green band representing the forecast next to the current amount of events. For example, if you select 1d, you will see the amount of events received over the last day at the left, and the forecast for the following day at the right. The forecast is calculated taken into account the data received from the last 3 days, 3 weeks... depending on the time period selected. |
| Periods related | Select this option to compare the amount of data received over the period selected with the data in previous related periods.
|
| Compare max/min, Compare % and Compare units | Choose the method you want the graph to calculate the green band, which represents the past average of events (default behavior), or the event count forecast (if the Periods related option is selected).
