Help: Nodes

The node pages under

allow managing information related to nodes:

node groups, nodes, interfaces, services, and network discovery.

This page is used to edit various node related objects. See below descriptions for details on editing each object.

html nodes.png Nodes

This page displays a tree of nodes, interfaces and services under each listed node.

Clicking on the

will focus

the display by hiding all other nodes.

Clicking on the

will expand

the tree showing all interfaces associated with the node.

Clicking on the

??? show rrdtool graphs ???

Clicking on the

take you to the edit page for that node.

html interface.png Interfaces

Each interface is listed by any known name and ip address.

Clicking on the

will expand

the tree showing all services associated with the interface.

Clicking on the

??? show rrdtool graphs ???

Clicking on the

take you to the edit page for that interface.

Clicking on the

??? show rrdtool graphs ???

Clicking on the

take you to the edit page for that service.

html groups.png Node Groups

This page lists groups of nodes. Node groups are a means of organizing your network and decluttering the display. You might group nodes by type of machine (e.g., Sun V40), application (e.g., Oracle) or geography (e.g., West Coast Datacenter). By default the system creates the following groups:

Database Servers
DNS Servers
Mail Servers
Printers
Web Servers
Windows Machines
iTunes

During network discovery nodes are assigned to these groups as a convenience. Nodes may belong to more than one group.

Clicking on the

will focus

the display by hiding all other node groups.

Under each node group listed is the same tree structure as the above Nodes page. Clicking on the

expand the tree. Clicking again will UNexpand the tree.

Clicking on the

take you to the edit page for that node group.

Clicking on the

take you to the apply page for that node group.

html discover.png Network Discovery

This page allows you to see the current set of subnets being monitored. You may add new subnets and interactively run network discovery. The frequency of automated network discovery can be controlled.

Subnets

This frame displays the current subnets considered in network discovery. Unchecking the checkbox Active next to each subnet will remove the subnet from the discovery process. This can be useful if you have just added a new subnet (see New Subnet) and you want to run discovery just on that new network (you uncheck all other subnets).

Checking the Deleted checkbox next to the subnet will from it from disovery process as well as the display. Use the Show Deleted control to see deleted subnets.

New Subnet

To create a new subnet to search when running network discovery input either a subnet mask in CIDR notation or single IP.

Run Schedule

This displays the options for the automated running of network discovery. Since this can cause considerable network traffic and may take many hours if you have multiple subnets, each with hundreds of nodes, you should consider scheduling network discovery carefully. There is the option to disable the automated running of network discovery and only do manual network discovery.

Run Discovery

Run network discovery now on all active subnets.

Show Deleted

If you have permission to update the data, then you will see displayed on the lower left hand part of the screen a check box. The Show Deleted check box, if checked will cause the display to show all deleted objects.
