Understanding the Monitor Mode Tasks Pane
The Tasks pane in Monitor mode displays a list of tasks that are available for the currently selected Monitor tab. These tasks provide monitoring functions in addition to the monitors available under each tab. The Monitor icon on the Edge Services Director is available or accessible only when you select Gateway View and Service View from the View selector.
Monitor mode in Edge Services Director provides you visibility into your network status and performance. Edge Services Director monitors its managed devices and maintains the information it collects from the devices in a database. Monitor 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.
The main purpose and benefit of monitoring functionalities is to allow the operators to quickly monitor the health (working condition), operating efficiency, traffic-handling capacity, and performance status of the managed SDGs and configured services such as ADC, TLB, CGNAT and SFW. The SDG monitoring mechanism is an extensive and ingrained tool; it allows the operator to understand the network health and status by drilling down to all the components of SDG. The SDG status is marked as Green, Red, Orange or Gray, based on the health, availability, performance and other important KPI indicators. Red denotes an emergency condition, which is a system panic or other conditions that cause the routing platform to stop functioning. It also indicates that the device is offline or turned down. Orange denotes an alert, which can be conditions that must be corrected immediately, such as a corrupted system database. Green indicates a notice, which signifies conditions that are not error conditions but are of interest or might warrant special handling. It can also include a severity level equivalent to informational or debugging messages. Gray signifies an unknown or an unconnected device that is out of synchronization.
The Monitoring page is refreshed automatically every 3 minutes. Static polling occurs to obtain and display data, and asynchronous collection is not used.
The Master and Standby tabs display information about the primary or master, and standby or secondary SDGs in an SDG pair. The Service Wait tab is displayed if the standby device is not fully active after a switchover.
