Advanced Line Graph

Like the Line Graph widget, you can use the Advanced  Line Graph widget to represent a time series metric, but with the addition of a table that provides the following supplemental details:

  • Value

  • Minimum value over the defined time range

  • Maximum value over the defined time range

  • Availability

  • Number of incidents related to the metric

Metrics can be for a single instance or spread across multiple instances. Like most widgets, you can scope the results to specific instances and metrics using a variety of filtering options.

Use case 

The Advanced  Line Graph widget is useful when:

  • Identifying performance trends

  • Comparing period over period performance

  • Comparing individual metric values

  • Exact values are required

Examples 

HTTP response time comparison 

In this example, the Advanced Line Graph displays the HTTP response time values of all the Linux web servers. The dotted line represents the historical value of the selected metric. Below the line graph, the data is presented in the form of a table. 

Configuration 

When creating or editing a widget, a drawer that shows the widget's configuration options slides out from the right. Each configurable option is described in the following table.
