I recommend the SLP best practice manual - I was the right document for me when I started working whit SLP. Have fun reading :-)

You would need to 1st configure an SLP with your desired operations and then use the SLP in a policy - specifying the SLP as the storage unit for the policy.

For SLP related logs:

If the duplication jobs do not come up in the activity monitor you would need to check if the SLP is active or not. If the SLP is active you would need to check if the nbstserv process is running. If yes then you would need to enable the nbstserv logs (OID 226)

If the duplications jobs come in the activity monitor and then fail with an error code you would need the "admin logs" to troubleshoot the bpduplicate process or other relevant logs.

For basics of SLPs you may refer to the Netbackup Admin Guide Vol 1 Chapter 14

NetBackup Administrator's Guide for Windows, Volume I

NetBackup Administrator's Guide for UNIX and Linux, Volume I

You may also take a look at the below video which shows how to create an SLP

For quick commands related to SLP you can refer to the SLP cheat sheet found in the following link

The SLP cheat sheet covers most of the details related to SLPs including the logs required as well as the commands to check the SLP state or modify SLPs.

And last but not the least the SLP best practices guide will cover all other aspects including managing backlogs, tuning the SLPs using the LIFECYCLE_PARAMETERS file, etc.
