The Alerts Dashboard

The Alerts Dashboard displays the currently triggered alerts; if opened from the Global Overview, the dashboard displays the current alerts for all monitored nodes on the system. If the Alerts Dashboard is opened from a node within a monitored hierarchy, the report will reflect alerts related to that node, and all monitored objects that reside below that object in the tree control.

The Alerts Dashboard header includes the date and time that the page was last updated and a current count of triggered alerts.

The Alerts Overview provides an overview of triggered alerts. The right-most bar indicates the total number of configured alerts that are not currently in an alert state; the three left-most bars indicate the number of Low, Medium and High alerts for the selected object. The vertical key on the left side of the graph provides an alert count.

The Alert Details table lists the currently triggered alerts for the selected object; if opened from the global overview, the Alert Details table lists all of the currently triggered alerts for all monitored objects. Click a column heading to sort the table by the contents of a selected column; click a second time to reverse the sort order. The table contains detailed information about each alert:

  • An alert level icon displays in red for a High severity alert, in orange for a Medium severity alert, and in yellow for a Low severity alert.
  • Use the arrow to the right of the alert level icon to access a dialog with detailed information about the alert. Within the dialog, the Details tab displays detailed information about the condition that triggered the alert; the Parameters tab displays the values of parameters used in the alert definition. Not all alerts return data that can be viewed on the Details dialog; for information about which templates display detailed metrics, please see the alert templates list
