Configuring the Unavailable Resources widget

Edit online

As a user of the Network Health Dashboard, you can configure which availability data is displayed in the Network Health Dashboard by the Unavailable Resources widget. For example you can configure the widget to display availability data based on ping polls only, and not based on SNMP polls. You can also configure the time duration thresholds to apply to availability data displayed in this widget. For example, by default the widget charts the number of device and interface availability alerts that have been open for up to ten minutes, more than ten minutes, and more than one hour. You can change these thresholds.
