Monitoring Capabilities Overview
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 mechansim 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.
Consider a sample scenario in which the SDG is marked as Red, which might be for various reasons. An operator that monitors using the Edge Services Director application with the Dashboard page learns that the device has been colored as red owing to the CGNAT feature (operator views the Service Status in the dashboard and it shows that CGNAT is marked red for this feature, which causes the SDG to be color-marked as red). The operator can quickly navigate to CGNAT from Dashboard using the Context Link to CGNAT. The Monitoring page provides the information that the SDG is marked as red because of the packet status drop. Therefore, the monitoring functionality helps the operator to quickly identify the issue. Edge Services Director simplifies and eases the complexity involved in monitoring the health and status of SDGs deployed across networks through following components and visual representation. The following is the list of components available as part of the Monitoring page for which you can analyze and diagnose the device problems and associated service errors.
When you log in to the Edge Services Director interface and navigate to the Monitoring page under Monitor mode, the Monitoring SDG is the landing page showing the details of a SDG. This view is split into two parts the left side is a navigation tree showing all the deployed SDGs. Each root node is the name of the SDG and the child nodes are the installed services ADC, TLB, CGNAT and SFW. Each service is a root node for the service instances.

You can view the health and status of the master and standby SDGs in a redundancy or high-availability pair.
The SDG and Alarms monitors are displayed at the upper half of the page.
The Statistics and Chassis View tabs are displayed at the lower half of the right pane of the Monitoring page. Under the Statistics tab, the alarms, high availability KPIs and switchover, status of services, and critical messages that are generated are displayed. The graphs are line graphs for the parameters shown in a pictorial way. Under the Chassis View tab, the hardware and line module details are displayed with a pictorial view of the slots of the SDG devices and the modules installed in these slots.
