Troubleshooting data collection

Statistics collection for Application Assurance reports

A blank report may be due to a statistics collection issue, or a prompt selection that excludes all available data.

The description of the report shows the statistics type required for the report, and whether an NSP Flow Collector is required. Table 5-1, Troubleshooting statistics collection for Application Assurance reports describes options for checking statistics collection.

Table 5-1: Troubleshooting statistics collection for Application Assurance reports

Statistics type	Items to verify	See
AA accounting	Are required policies in place? Are statistics being collected? What is the accounting retrieval status of the NE? Is additional information available from server performance statistics?	“Workflow for accounting statistics collection” in the NSP NFM-P Statistics Management Guide “Workflow for server performance statistics collection” in the NSP NFM-P Statistics Management Guide “To view the accounting statistics collection status of an NE” in the NSP NFM-P Classic Management User Guide
AA Cflowd	Has AA Cflowd sampling been configured? Are required policies in place?	“To enable and configure global Cflowd sampling on an NE” in the NSP NFM-P Classic Management User Guide “To configure Cflowd collectors on an ISA-AA group or partition” in the NSP NFM-P Classic Management User Guide “To configure an AA Cflowd group policy” in the NSP NFM-P Classic Management User Guide “Workflow to configure flow statistics collection” in the NSP NFM-P Statistics Management Guide If the report requires special study statistics collection, see “Workflow to configure AA Cflowd special study statistics collection” in the NSP NFM-P Statistics Management Guide
AA Cflowd	Is the NSP Flow Collector operating correctly? Is the Flow Collector mode correct? A single Flow Collector can collect AA Cflowd or IPFIX, but not both simultaneously.	“To display the NSP Flow Collector status” in the NSP System Administrator Guide Check the NSP Flow Collector logs to verify connectivity to the auxiliary database; see Troubleshooting data storage
Subscriber	Are required policies in place? Are statistics being collected?	“To configure AA subscriber statistics collection on an ISA-AA group or partition” in the NSP NFM-P Classic Management User Guide
Subscriber	Is the NSP Flow Collector operating correctly?	“To display the NSP Flow Collector status” in the NSP System Administrator Guide

Statistics and data collection for Network and Service reports and NSP reports

A blank report may be due to a statistics collection issue, or a prompt selection that excludes all available data.

The description of the report shows the statistics or data type required for the report, and any other prerequisites that may apply. Table 5-2, Troubleshooting statistics and data collection for Network and Service reports and NSP reports describes options for checking collection.

Statistics type	Items to verify	See
Accounting (also known as XML statistics)	Are required policies in place? Are statistics being collected? Are required aggregators configured?	“Workflow for accounting statistics collection” in the NSP NFM-P Statistics Management Guide “How do I configure analytics aggregation?” in the NSP Analytics Report Catalog
Performance (SNMP) data	Are required policies in place? Is SNMP connectivity established between the NE and the NFM-P? Are required statistics being collected? Are required aggregation rules enabled? Alarms: if the system cannot collect and process all performance statistics in the specified polling period, the PollerDeadlineMissed alarm will be raised.	“How do I configure analytics aggregation?” in the NSP Analytics Report Catalog
IPFIX (also called System Cflowd or Netflow v10)	Has IPFIX sampling been configured? Are required policies in place?	“Workflow to configure flow statistics collection” in the NSP NFM-P Statistics Management Guide
IPFIX (also called System Cflowd or Netflow v10)	Is the NSP Flow Collector operating correctly? Is the Flow Collector mode correct? A single Flow Collector can collect AA Cflowd or IPFIX, but not both simultaneously.	“To display the NSP Flow Collector status” in the NSP System Administrator Guide
OAM data	Is OAM testing configured in the NFM-P? Are required policies in place? Are OAM aggregation rules enabled?	“How do I configure analytics aggregation?” in the NSP Analytics Report Catalog
Event data for Uptime reports	Is an event log policy in place with an appropriate retention time for assurance events? Are maintenance windows configured appropriately?	“To configure an event log policy” in the NSP NFM-P Classic Management User Guide “To create and manage custom auxiliary database table attributes” in the NSP System Administrator Guide

NFM-P auxiliary database

In order to enable data collection, the auxiliary database must be configured and operational.

The NFM-P forwards statistics to the auxiliary database only if the auxdb-storage parameter is enabled in the aa-stats section of each NFM-P main server configuration. See the NSP Installation and Upgrade Guide for information about using the samconfig utility to modify the NFM-P configuration.

If you suspect an auxiliary database problem, you can run the following script on an auxiliary database station to collect log files for technical support:

/opt/nsp/nfmp/auxdb/install/bin/getDebugFiles.bash

NFM-P main database

For Inventory reports, the NFM-P main database must be operational and able to receive files from NEs.

To confirm that files are being received and stored, monitor the following folder on the standalone or primary main server to ensure that new statistics files are being generated:

/opt/nsp/nfmp/server/xml_output
