Using Foglight for NMS Integration
Foglight™ for NMS Integration monitors network devices such as switches and routers from your Foglight NMS environment that are connected to Foglight Agent Managers. It helps you analyze performance issues affecting the monitored switches, routers, and firewalls. It is used together with the Cartridge for Infrastructure, which enables access to the views included with Foglight for NMS Integration. The cartridge contains the following major components:
Investigating the Performance of Network Devices
Foglight™ for NMS Integration includes a set of switch, router, and firewall views that you can explore to investigate the performance of these network devices in your monitored environment. They display performance metrics, allowing you to analyze overall health levels, and identify potential bottlenecks.
The switch, router, and firewall views appear on the Infrastructure Environment dashboard, when the Switch,
Router, or
Firewall tile is selected. You must have Foglight for Infrastructure installed on the Management Server to access these views. For complete installation information and system prerequisites, see the
Foglight for NMS Integration Installation Guide.
Next, take a step further and investigate device statistics to obtain a better understanding of the state of the device’s network resources and how they affect your monitored system as a whole. These statistics appear on the Monitoring tab. This tab shows an intuitive view containing related network device statistics connected by a series of graphical flows. The information is updated in real time, illustrating how quickly the data is moving through the device. For example, review the overall send and receive rates as well as the rates generated by individual network interface adapters.
From there, click any of the overall send or receive flows to display additional information about the selected device in the Network Details view. Explore historical network utilization along with data and data packet send and receive rates per-device, and review all network interfaces on the selected device. You can select an interface and show additional information about it, such as the interface network utilization, data and data packet send and receive rates, amounts of dropped data packets, inbound and outbound errors, and the outbound queue length, all over the selected time range.
Next, return to the Monitoring tab using the breadcrumb trail, and drill down on any of the send or receive rates for individual network interfaces to display the
Network Interface Details view. This view shows basic configuration details of the selected interface along with a set of graphs displaying the interface network utilization, data and data packet send and receive rates, amounts of dropped data packets, inbound and outbound errors, and the outbound queue length, over the selected time range.
Finally, observe the network traffic for different groups of network flows (applications, conversations, domains, endpoints, protocols, and interfaces) on the Top Network Traffic tab. For most groups, you can quickly discover which user caused the spike, where they went, what port they were using, and the amount of traffic that was generated. You can also see the length of time during which the traffic occurred.

On the Monitoring tab, click the box in the top-left, and from the list that appears, select Network. |
The Monitoring tab refreshes. The upper part of the monitoring tab shows three tiles, each identifying a specific collection of monitored network devices:
Firewalls,
Switches, and
Routers.
The Quick View refreshes, showing the views associated with the devices of the selected type.
The Quick View displays a list of all network switches or routers (as selected), and identifies the ones with the highest transfer rates, and memory, network, and CPU utilization. It also contains a list of alarms generated against any of the monitored switches.

In the Quick View, in the Switch or Router embedded view, select a switch or router. |
The Quick View refreshes, displaying information about the selected object.
The Quick View displays general information about the selected device, along with CPU and memory metrics, network details, and any related alarms.

In the Quick View, click Explore. |
The Network Details view appears.
|
d |
On the Monitoring tab, click any of the send or receive rates for an individual network interface. |
The Network Interface Details view appears.
Exploring Network Device Services
Foglight™ service mechanisms allow you to organize monitoring components into logical groups. A primary use case for this is for a multi-tier application where objects are organized into service tiers and visualized in the Service Operations Console.

TIP: The Dependencies tab is included with Foglight for Dependency Mapping. This is a required component when you install the Cartridge for NMS Integration. To learn about system requirements, see the Foglight for NMS Integration Installation Guide. For details about Foglight for Dependency Mapping and the Dependency tab, see the Foglight for Dependency Mapping User Guide. For complete information about services in Foglight and the Service Operations Console dashboard, see the Foglight User Help. |

On the Dependencies tab, click More Devices. |
The More Device Details dialog box appears.
Exploring Network Devices through Host Dependencies
In most cases, a monitored environment can contain a large collection of hosts and services. These collections can be quite complex and the hosts and objects they contain are often dependent on each other. Foglight™ for Dependency Mapping reveals these dependencies, allowing you to have a better insight into the existing model. By exploring these dependencies, you can drill down on specific hosts and observe the performance of the associated network devices.
The Network Devices tab shows a collection of tiles, each representing a network device associated with the selected host. Each tile displays the device state, alarm counts, network transfer rate, data packet transmission rates, network utilization, and the number of network interfaces. For complete information about the information appearing on this tile, see
Network Device tile .
Next, review the dependency details on the Dependency Detail tab, drill down on a specific dependency detail related to a network device, and observe the device performance and its data transfer and bandwidth metrics.
