NSP auxiliary database

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:
