EV Observe - Widget - Graph icon.png This type of widget is used to display a chart showing changes in metric values for configuration items (CIs) over a period of time.

  • You can display several CIs (hosts/services) in the chart in order to monitor and compare changes in a given metric over time, i.e. single-metric mode.
  • You can display several metrics of a single CI in the chart to correlate and monitor all events that may cause issues for the host/service, i.e. multi-metric mode.



  • Monitor application bandwidth usage over time using NetFlow
  • Monitor the time required for accessing an application website
  • Monitor cluster infrastructure by tracking simultaneous variations of a given metric in different load balancing hosts

  • The maximum number of metrics that can be displayed in a given chart is ten.
  • Warning and critical thresholds are displayed only in single-metric charts.
  • The metric value will appear when the cursor hovers over the chart.
  • Charts are synchronized so that you can compare values at a given time easily.
