7.4.4 Working with Network Maps




 

Map is a graphical representation of networks and network elements (NEs). Network elements, such as desktops, workstations, storage devices, servers, notebooks, printers, switches, routers, etc., which are connected in a network can be represented pictorially in a map.

 

The Network Maps provides you lucid and accurate information on the state of network elements. Its change in state is represented using colors which make you identify faults in the network with ease.

 

Viewing Maps

 

By default, when you log in to the web client, the Home page is displayed. To view the map, click Maps module tab in the web client.

Understanding Map Types

 

When you open the Maps view, the Maps tree is available in the left side. This tree has the following types of maps (as tree nodes):

All information and operations available in the various network maps are also available in the Network Database view. For example, all the networks and the operations that can be performed in the ipnet map are also available in the Inventory  > Complete view. The maps are graphical representation of network elements while the Inventory view is a tabular representation of network data.

 


Note

The map types differ based on the devices in your network. The new maps that you add will also be depicted in the Network Maps tree.

 

ipnet Map

 

The ipnet map depicts all the networks and routers that are discovered.

 

IpNet Map

 

To view devices in a network

 

Click the network symbol in the ipnet map. All devices discovered in that network is displayed. It also traverses you to the Sub-network node in Network Maps tree.

 

Routers Map

 

The Routers map depicts all the routers discovered in the network. This map is added dynamically only after at least one router is discovered.


Switches Map

 

The Switches map depicts all the switches discovered in the network. This map is added dynamically only after at least one switch is discovered. Refer the screen shot given below for working on the Switches Map.

 

Switch Map


1
- Indicates the severity of the switch.

2 - Indicates the severity of the port.

3 - Click to view switch details.

4 - Click to view port details.

 

 

 

Printers Map

 

The Printers map depicts all the printers discovered in the network. This map is added dynamically only after at least one printer is discovered. Refer the screen shot given below for working on the Printers Map.

 




 Right click on the printer symbol to view the properties of the printer.

 

Failed Systems Map

 

The Failed Systems map depicts all the devices in the network that has failed. A network element is said to have failed if it has not responded to the regular monitoring checks done by Web NMS. This map helps you easily identify the devices that have failed in the network and enables you to take quick action henceforth.


Sub-network Map

 

A Sub-network map is named after the IP address of the network discovered. For example, if a network say 192.168.1.0 is discovered, then a node named 192.168.1.0 is available in the Maps tree. Similarly, for every network that is discovered a sub-network map is available.

 

Clicking the sub-network map depicts only the devices discovered in that network, on the right-side frame. Each sub-network map node in the Maps tree has child nodes, such as Routers, Switches, Printers, and Failed Systems which depict their corresponding devices discovered in that network only.

Viewing Network Element Details

 

To view a network element's detail

Detailed information of that network or device is displayed. In a Switch, clicking each port displays detailed information on that port.

 

For example, if you need to view the details of a printer

The same device details can also be viewed from the Inventory view. For more information, refer to Viewing Network Element Details section in Working with Network Database topic.

Managing/Unmanaging Network Elements

 

By 'managing a network element' we mean that the element is being monitored by Web NMS. By default, Web NMS monitors all the devices that it discovers. Regular check is done by Web NMS to gather information on a network element's integrity. This option can be disabled by unmanaging the network element which consequently stops the Web NMS from monitoring that element.

 

To manage/unmanage a network element

    1. In the desired map, right-click on any network element symbol.

    2. Click Manage/UnManage from the menu displayed. . A network element has only either Manage or Unmanage option based on its status. For example, if a device is already in an unmanaged state, then only Manage option is available.

An unmanaged network element can be identified by its icon - .

Deleting Network Elements

 

To delete a network element

    1. In the desired map, right-click on the desired network element symbol.

    2. Select Delete Object and Traces option from the menu displayed.

On performing this, the element is deleted from the map as well as from the database. If you have deleted a network, then the network and all the devices in that network is also removed from the map and the database.

 

The same network or network element can also be deleted from the Inventory view. For more information, see Deleting Network Elements section in Working with Network Database topic.

Viewing Performance Reports of a Network Element

 

To view performance reports of a network element

 

    1. In the desired map, double-click on the desired network element symbol.

    2. In the resulting inventory page, scroll down to see graphical reports for CPU Utilization, Memory Utilization etc.

For more information, refer to Viewing Performance Reports topic.

Viewing  SNMP Information of a Device

 

To view SNMP information for a network element

    1. In the desired map view, double-click on the desired snmp device.

    2. In the resulting inventory page, scroll down to see graphical reports for CPU Utilization, Memory Utilization etc. and Performance Details. Select from the Statistics lists to view a specific data in graphical format.

For more information on the tables, refer to Viewing Advanced Information of a Device.

Viewing Event and Alarms

 

To view events related to a network element

    1. In the desired map view, right-click on the desired snmp device.

    2. Click View Events or View Alarms from the menu displayed.

On performing this, all events or alarms related to that network element are displayed. For more information, refer to Working with Network Events and Working with Alarms.

 

 

Tip: Another quick way to view the severity and its details of a network element from a map view is by clicking the severity icon above the network element symbol.

 

- Clear

- Critical

- Info

- Major

- Minor

- Unmanaged

- Warning

Performing Map Operations

 

Apart from the default maps that you view in the web client, you can add your own custom maps. This is similar to the custom views that you create. Similarly, map elements, such as symbols and links can also be manually added in your maps. These options are available to you based on your user privileges. Contact your system administrator to know your user privileges.
