Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Performance Graphing
This topic includes the following sections:
- Launch Performance Troubleshooting from the Incident View
- Access the Performance Troubleshooting Console
- Find Connection Data in the NNMi Analysis Panel
- Find Interface Data
- Find Node Data
- Find Node Fault Data
- Find Node Performance Event Data
- Find SNMP Agent Data
- Find Connection Data for a Node
- Find Interface Data for NNMi Ports
- Find Interface Performance Event Data
The Performance Graphing window displays graphs that provide data about connections, nodes, and interfaces on your system.
To use this feature:
-
Select a performance-polled node from the NNMi node inventory view. Click Actions > NNM iSPI for Performance > Performance Troubleshooting. The Performance Graphing window is launched for only the selected node.
All the interfaces of the node are also available.
-
Select a performance-polled interface from the NNMi node inventory view. Click Actions > NNM iSPI for Performance > Performance Troubleshooting. The Performance Graphing window is launched for the selected interface.
The interface appears under the parent node in the tree. All other interfaces of the node are also visible.
If the interface is not being polled, the panel is blank.
Performance Tab in the NNMi Analysis Pane
In addition to providing the Performance Graphing console, NPS enables you to view the performance graph of a selected network element in the Analysis pane in an inventory view. The Analysis pane shows the performance graph in the Performance tab.
The time scale displayed on a graph represents the time on the client system where you launched the graph with a web browser and not the time on the NPS system or the NNMi management server.
Launch Performance Troubleshooting from the Incident View
In the NNMi Incident View, you can launch the Performance Troubleshooting window for the performance and fault incidents.
To launch the Performance Troubleshooting window:
- Log on to the NNMi console as an administrator or operator.
- Go to the Incident View.
-
Right-click an incident of your interest, and then click NNM iSPI Performance > Performance Troubleshooting.
Alternatively, click Actions > NNM iSPI Performance > Performance Troubleshooting.
The Performance Troubleshooting window opens and shows a graph that is plotted with the data from two hours before and until two hours after the incident occurred.
For performance incidents, the Performance Troubleshooting window shows graphs of metric that is the cause of the incident.
For fault incidents (such as node down), the Performance Troubleshooting window shows graphs of CPU and memory utilizations of the node that is the cause of the incident.
For the performance and fault incidents, NNMi adds a new Performance tab in the Analysis pane and shows performance graphs.
Access the Performance Troubleshooting Console
For operational performance management, NNMi supports an external launch to the performance analysis panel, which creates graphs that enable you to analyze the topology objects (nodes and interfaces) on your system.
To access this feature, go to the NNM console. Select either a node or an interface, open the Actions menu, select Performance > Troubleshooting.
The Performance Troubleshooting window is divided into two panes. Pane 1 shows a tree view with the root node called Network. When expanded, all the nodes on the network that were performance polled are shown. The interfaces for these nodes are also shown. Pane 2 appears blank. However, if you unselect the Quick view option, a third pane appears showing two graphs, Pre-defined and Metrics.
You can drag and drop metrics to produce graphs for a selected time period.
In this console, you can create graphs with all the metrics from all installed Extension Packs (including Custom Poller Extension Packs).
Find Connection Data in the NNMi Analysis Panel
You can find data for NNMi L2 connections through the performance analysis panel.
To use this feature, select an interface in a view in the NNMi console.

To select a performance incident for a performance-polled node, start from the NNMi Incident view in the NNMi console. If NNMi detects that a node is violating a configured performance metric threshold—for example, CPU utilization—a CPUOutofRangeOrMalfunctioning event is generated and made visible in the Incident view. When you click this incident, a performance tab appears in the analysis pane. When you click the tab, the graphs described below appear.
Supported events are:
