To view the overall network health of all networks in Kemp 360 Central, click All Networks. This informs you about the overall health percentage of your network including the number of devices, Virtual Services, Real Servers, and Sub VSs that are up or down.

This section of the document fully explains the various sections and headings shown in the screenshots above. Network Health shows an aggregated health percentage value for the network currently selected in the left frame, calculated using the number of devices with an UP status on the network, against the total number of devices in that network. A separate health value is displayed for Devices, Virtual Services, Real Servers, and SubVSs.

SubNetworks health shows the status of each subnet individually. The subnetwork health percentage is based on the number of UP devices in the subnetwork against the total number of devices in that subnetwork.

Hovering over the subnetwork health icon displays the Nickname, Device Status, Service Status, SubVS Status, and Real Server Status.

In the Devices section, an icon is displayed for each device on the network. A red icon means that the device is down. A grey icon means the device is disabled. A green or blue icon means the device is up (blue is used to indicate a LoadMaster that was licensed using the local licensing functionality).

Hovering over the device icons displays the device type, IP address, the status of that device, and the device nickname - if available.

Hovering over the header at the top of the User Interface (UI) also displays the full nickname for the device.

When a network is selected on the left, the Real Servers section displays – if available. In the Real Servers section, there are icons for each Real Server on the network. Green indicates the Real Server is up while red means the Real Server is down. Hover help displays the Health Status, Admin Status, LoadMaster IP address, Virtual Service IP address, and the VS Nickname, if available, of individual Real Servers.

When a network is selected on the left, the Real Servers section displays – if available. In the Real Servers section, there are icons for each Real Server on the network. Green indicates the Real Server is up while red means the Real Server is down. Hover help displays the Health Status, Admin Status, Loadmaster IP address, Real Server IP address, Virtual Service IP address, and the VS Nickname, if available, of individual Real Servers.

In the SubVSs section, there are icons for each SubVS on the network. Green indicates the SubVS is up while red means the SubVS is down. Hover help displays the Health Status, Admin Status, Loadmaster IP address, SubVS number, SubVS Nickname, if available, Virtual Service IP address, and the VS Nickname, if available, of individual SubVSs. The SubVS Nickname displayed on Kemp 360 Central is the same as the nickname used for that SubVS on the LoadMaster. The tooltip displays the full SubVS Nickname. The SubVS number is the same number used on LoadMaster on the SubVS configuration screens (click View / Modify Services > Modify > SubVSs); they are not the numbers displayed in the View /Modify Services table).

When users select an individual LoadMaster, the status of its Virtual Service(s) and Real Server(s) appears above the Connections graph, as shown in the following figure:

A green icon indicates that the Virtual Service or Real Server is up, a red icon indicates it is down and a grey icon indicates it is disabled.

Note: The shared IP is not found in Network and Device Health.
