Historical Trends

You can view historical trend data directly within the web UI interface. When you see a metric you want to investigate further, you can select to view historical data for the past several days.

Historical data is available for metrics that are related to:

• Machines that have the ControlUp Agent installed
• Sessions running on machines with the ControlUp Agent installed
• Hosts that are monitored in your ControlUp environment

You can select to view historical trends for:

• Single entities in the grid of the Discovery view
• Multiple entities in the grid of the Discovery view
• Dashboard widgets in the Dashboard view or the Discovery view

Single Entity

You can view historical trends for a single entity, or a specific metric within an entity.

Let's say you have a machine or session that is showing over 90% percent CPU usage and you want to know for how long it has been performing at that state.

To view historical trends for a single entity:

From the real-time grid on the Discovery page, right click on the entity's row and select Historical report.

The historical trend page opens for the entity, showing detailed historical data for all relevant metrics.

To view historical trends for a single metric:

Hover over a relevant metric and click the clock icon to see historical data for only that metric.

An overlay displays the selected metric for the past 24 hours. You can also select to view 48 or 72 hours.

You can click on the arrow icon next to the hours selection to expand the overlay and open the historical trend page for the entity.

Historical Trends Page

In the historical trend page opened using either of the methods above, you can see historical data on several metrics for the host, machine, or session. For example:

• CPU Utilization
• Memory Utilization
• I/O Utilization
• Network Usage
• User Sessions

You can select to view the graphs in boxes or in a row. You can also select to view the data for the past 24 hours, 72 hours, 1 week, or 1 month.

Multiple Entities

You can view historical trends for up to 10 entities in the Discovery view grid. This is useful if you want to see a comparison between the metrics for several entities over time.

Note that you can't compare session metrics in the same way. Selecting multiple sessions brings you to a different historical page (Session Activity) than selecting a single session (Session Details).

To view the historical trend for multiple entities:

1. Hover over the area of the grid to the immediate left of the object's name and click to select that object.
   
2. Repeat for all the objects you want to select for this historical trend view.
3. Once you have made all your selections (of only up to 10 objects), click the Trends icon at the top of the grid or right click one of the selected entity and click Historical Reports.
   
   The Trends window opens displaying the metrics for all the selected machines, represented by different colors for each object in each graph.
   

Dashboard Widgets

The relevant Dashboard Widgets in both web UI's Dashboard view and Discovery view include the ability to view historical trends. The widget's data has to be mapped to the monitoring information for machines or hosts . The relevant dashboards widgets include Machines Average CPU Usage, Machines Total Network Throughput, Hosts Average RAM Usage and more.

You can identify a relevant widget if you see the clock icon in the right side of the widget.

When you click the clock icon, the widget flips over to the historical trend view where you can select from the most previous 24, 48 or 72 hours. To return to the real-time view, click the open triangle to the right of the hour selection.
