About Fault Mode in All Views of Connectivity Services Director
Fault mode in Connectivity Services Director provides you visibility into your network status and performance by displaying alarms and events generated on devices and configured services on devices. Connectivity Services Director monitors its managed devices and maintains the information it collects from the devices in a database. Fault mode displays this information in easy-to-understand graphs and in tables that you can sort and filter, allowing you to quickly visualize the state of your network, spot trends developing over time, and find important details. When certain types of events are persistent, or when the condition causing the event crosses a threshold, SNMP sends a notification, also called a trap to Connectivity Services Director.
