Network Reporting Issues

This section includes common issues with network reports and the steps to resolve these issues.

Data Gaps on Reports

This can occur when NPS detects a conflict between the polling interval and the display grain selected for the report.

When you select a finer grain for your report than the polling interval selected in NNMi, NPS displays all the intermediate time entries and the data available for them. If these intermediate time entries do not contain any data samples, the reports might display missing entries in tables or gaps on the graphs and charts.

To resolve this, set a greater display grain for the report than the polling interval defined for the device in NNMi. For example, if the polling interval for the interface is configured as 1 minute, make sure that the display grain for the reports related to the interface is at least 1 minute.

Navigation Panel Without Any Reports

When the navigation panel in the NPS console does not show any reports, follow these steps:

  1. Go to the Reports tab in the navigation panel and click Refresh.

  2. If reports still do not appear, log on to the NPS system, and then run the following commands to restart the BI Server (in a distributed deployment of NPS, run these commands on the UiBi Server):

    1. stopBI.ovpl
    2. startBI.ovpl

  3. If reports still do not appear, log on to the NPS system, and then run the following commands (in a distributed deployment of NPS, run these commands on the UiBi Server):

    1. stopALL.ovpl
    2. startALL.ovpl

Missing Reports in a GNM Environment

In a GNM environment where each regional manager is configured with an NPS and the global manager is also configured with a dedicated NPS instance, the following error message may appear when you try to launch a report:

DPR-ERR-2107
The user capabilities cookies cannot be decoded

You are likely to see this error message when you do the following:

  1. Log on to the NPS console associated with the global manager.
  2. Log on to the NNMi console of one of the regional managers.
  3. Launch the NPS console from this regional NNMi console.
  4. Launch one of the reports in the NPS console.

This error appears when the Regional Manager and Global Manager are in different domains.

Follow these steps on all NPS systems available in the GNM environment (In a distributed deployment of NPS, do this only on the UiBi Server):

  1. Log on to the NPS system as root or administrator.

  2. Run the following command:

    • On Windows: %NPSInstallDir%\bin\runBIConfigGui.ovpl
    • On Linux: /opt/OV/NNMPerformanceSPI/bin/runBIConfigGui.ovpl
  3. In the NNM iSPI Performance BI Configuration window, click Actions > Edit Global Configuration.

  4. In the Global Configuration dialog box, specify the following values:

    • Domain: specify the FQDN of the NPS system (or the FQDN of the UiBi Server in a distributed deployment of NPS).
    • Path: specify /.
    • Secure flag enabled: Select yes.
  5. Click OK.

  6. Restart the BI Server by running the following commands:

    1. stopBI.ovpl
    2. startBI.ovpl

BI Server Error

The following error messages appear in the command line console when you run the startBI.ovpl or startALL.ovpl command:

WARN: Failed command system(./cogconfig.sh -java:local -s > "/var/opt/OV/NNMPerformanceSPI/logs/startBIServices.log" 2>&1): 512

This error may appear if a large number of Extension Packs are installed on the NPS system.

To resolve this problem, follow these steps:

  1. Log on to the NPS system as root or administrator.

  2. Go to the following directory:

    • Windows: %npsinstalldir%\..\nonOV\cognos\bi\configuration
    • Linux: /opt/OV/../nonOV/cognos/bi/configuration
  3. Open the cogconfig.prefs file with a text editor.

  4. Add the following lines: 

    ServiceMaxTries=1200
    ServiceWaitInterval=2400
  5. Save the file.

  6. Run the following commands:

    • stopBI.ovpl
    • startBI.ovpl
