A Schematic Map shows percentage load on connections between nodes on the network. This is calculated using the data from SNMP Traffic measurement jobs on the Reporting Paths. The load on the connection is the percentage of the sum of the bandwidths used by the sum of the recently measured traffic.
Different Schematic Maps can be created to show different regions of the network. Some of these maps may be visible to users who are not logged into Netsight. Others may only be visible to specific people when they have logged in. For more information about creating and editing Schematic Maps, see the Schematic Maps Maintenance help page.
To view Schematic Maps of the network traffic, select "Home" from the Menu Bar, then "Network Maps" from the Side Menu. A list of available Schematic Maps is shown. You can click on any of the listed maps to view the map itself.
Initially the Schematic Map shows a set of top-level nodes and reporting paths between these nodes. You can return to this view at any time by clicking "Reset View" near the top-left-hand corner of the map. The map shows the visible Nodes as circles and the Reporting Paths between them as arrows. The weight of these arrows corresponds to the sum of the link speed of the Reporting Paths between these nodes; Heavier lines indicating connections with higher bandwidth. The direction of the arrow shows the direction of the traffic on the Reporting Path that that arrow represents. There are therefore two arrows per Reporting Path, to show the traffic in each direction. The volume of traffic is measured in terms of the traffic into and out of the A end using the most recently defined traffic job. If there is no traffic job at the A end the B end is used.
The list of bandwidths for the Reporting Paths is shown between the arrows. The percentage load for all reporting paths is shown in the middle of each arrow. The arrow is coloured depending on the load in one of these categories.
Percentage load |
Map Line Colour |
Details |
| High | Red | Over 50% of the link's bandwidth is in use. |
| Medium | Yellow | 30%-50% of the link's bandwidth is in use |
| Low | Green | Less than 30% of the link's bandwidth is in use. |
| No recent traffic measurement | Grey | The volume of traffic on this reporting path could not be measured. This means that there is no recent data from the measuring job. |
| Bandwidth unknown | Black | If a reporting path has no user defined link speed and the interface at the end the measurement job targets has not been discovered then the bandwidth is unknown. |
| No shown reporting path | Dotted Grey line | If a reporting path exists between nodes but has been hidden on this map then the nodes are linked with a dotted grey line. |
You can zoom the map to centre on a different node by clicking on the node of interest. When you do this, Reporting Paths connected to the Node clicked on that were not previously visible may be revealed, plus the Nodes at their far ends. In this way, by clicking on the Nodes you are interested in, you can navigate around the Schematic Map and view the traffic over the network.
