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 |

Maintain Reports
This topic includes the following sections:
- Enable Subnet Details on Traffic Reports
- Enable Data Collection for Reports for Top Destination Ports
- Disable Data Generation for the Interface Traffic Reports
The NNM iSPI Performance for Traffic enables you to view reports that provide you an insight into the network traffic and helps you monitor network performance by analyzing the traffic flow. All the reports are not available by default as enabling few of them may increase the load on the NNM iSPI Performance for Traffic and NPS. This section describes how to enable or disable these reports based on your requirements to enhance the performance of the NNM iSPI Performance for Traffic.
Enable Subnet Details on Traffic Reports
The NNM iSPI Performance for Traffic enables you to view Source Subnet Address and Destination Subnet Address in the Traffic reports. However, these subnet details are not visible on the Traffic reports by default. You must perform additional configuration steps to be able to view subnet details on the NNM iSPI Performance for Traffic reports. Enabling the subnet details may increase the load on the NNM iSPI Performance for Traffic and NPS. Therefore, you may require additional system resources, such as CPU, memory, and disk space.
Subnet details are available in the Report Options in the Grouping By list on the following reports:
- Interface Traffic reports: Most Changed, Top N, Top N Chart, and Top N Table
- Interface Traffic Aggregated and Interface Traffic 1-minute reports: Top Interfaces reports for Top N
Analysis, Top N Chart Analysis, and Top N Table Analysis
The Interface Traffic_1_min reports are disabled by default. For information on how to enable these reports, see the Configuring Master Collectors section in the Network Node Manager iSPI Performance for Traffic Software Online Help.
When the subnet details are disabled, the Source Subnet Address and Destination Subnet Address options are available in the Grouping By list. However, the subnet address is shown on the report as 0.0.0.0/0.
To view subnet details in the Traffic reports, follow these steps on Leaf Collector system:
-
Log on to the Leaf Collector system as an administrator on Windows and as root on Linux.
-
Open the nms-traffic-leaf.address.properties file with a text editor.
- Add the enable.subnet.report property and set it to true.
-
Save and close the file.
-
Start the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstart.ovpl
Enable Data Collection for Reports for Top Destination Ports
Data collection for the following reports is disabled by default:
- Interface Traffic Aggregated Top Sources for Destination Port
- Interface Traffic Aggregated Top Destinations for Destination Port
- Interface Traffic Aggregated Top Conversations for Destination Port
- Interface Traffic_1_min Top Sources for Destination Port
- Interface Traffic_1_min Top Destinations for Destination Port
- Interface Traffic_1_min Top Conversations for Destination Port
Enabling these reports may increase the load on the NNM iSPI Performance for Traffic and NPS. Therefore, you may require additional system resources, such as CPU, memory, and disk space.
The Interface Traffic_1_min reports are disabled by default. For information on how to enable these reports, see the Configuring Master Collectors section in the Network Node Manager iSPI Performance for Traffic Software Software Online Help.
To enable data collection for Top Destination Ports reports:
- Log on to the Leaf Collector system as an administrator on Windows and as root on Linux.
-
Stop the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstop.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstop.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstop.ovpl
-
Navigate to the following directory:
On Windows
%TrafficDataDir%\nmsas\traffic-leaf\conf
OR
%NNMDataDir%\nmsas\traffic-leaf\conf
On Linux
/var/opt/OV/nmsas/traffic-leaf/conf
-
Open the nms-traffic-leaf.address.properties file with a text editor.
-
Add the following line:
topn.subtypes.dstport=true
Addition of this line enables data collection for the Top Conversations for Destination Port reports.
-
Add the following line:
enable.srcordst.dstport=true
Addition of this line enables data collection for the Top Sources for Destination Port and Top
Destinations for Destination Port reports.
- Save and close the nms-traffic-leaf.address.properties file.
-
Start the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstart.ovpl
To disable data collection for Top Destination Ports reports:
- Log on to the Leaf Collector system as an administrator on Windows and as root on Linux.
-
Stop the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstop.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstop.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstop.ovpl
-
Navigate to the following directory:
On Windows
%TrafficDataDir%\nmsas\traffic-leaf\conf
OR
%NNMDataDir%\nmsas\traffic-leaf\conf
On Linux
/var/opt/OV/nmsas/traffic-leaf/conf
- Open the nms-traffic-leaf.address.properties file with a text editor.
-
Do one of the following:
-
Remove the following line of code:
topn.subtypes.dstport=true
- Set the property topn.subtypes.dstport to false.
-
- Save and close the nms-traffic-leaf.address.properties file.
-
Start the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstart.ovpl
Disable Data Generation for the Interface Traffic Reports
When the NNM iSPI Performance for Traffic is configured in large-scale environment, you must disable the data generation for the Interface Traffic reports for optimum performance.
To disable the data generation for the Interface Traffic reports:
-
Log on to the NNM iSPI Performance for Traffic Configuration form.
- Click Master Collector. The Master Collector Details page opens.
- Locate the Interface Traffic Data Flush parameter and click Edit.
- Set the Value field for the Interface Traffic Data Flush parameter to Disable Flush.
- Click Save.
-
Start the Leaf Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl or
%TrafficInstallDir%\traffic-leaf\bin\nmstrafficleafstart.ovpl
On Linux
/opt/OV/traffic-leaf/bin/nmstrafficleafstart.ovpl
-
Start the Master Collector by running the following command:
On Windows
%NnmInstallDir%\traffic-master\bin\nmstrafficmasterstart.ovpl or
%TrafficInstallDir%\traffic-master\bin\nmstrafficmasterstart.ovpl
On Linux
/opt/OV/traffic-master/bin/nmstrafficmasterstart.ovpl
