Trying to migrate from Splunk DB Connect 1 to DB Connect 2, why is the inputs.py migration script not working?

After following the migration process to migrate from DB Connect 1 to DB Connect 2 located here

  • splunk cmd python dbx_migrate_connections.py - worked
  • splunk cmd python dbx_migrate_lookups.py - worked
  • splunk cmd python dbx_migrate_inputs.py didn't work

Fails silently with no exceptions or outputs.

Answering my own question here, to save folks time and agony in finding a solution.

Our existing database names contain hyphens and underscores (ex. database-things_are-in-dev) which the migration script fails on, to fix edit the following line in

/opt/splunk/etc/apps/splunk_app_db_connect/bin/dbx2/migration/migrations/input/001_migrate_from_dbx1.py

Change this:

name_pattern = r'dbmon-(?P<type>\w+)://(?P<database>\w+)/(?P<unique_name>\w+)'

to this:

name_pattern = r'dbmon-(?P<type>\w+)://(?P<database>\S+)/(?P<unique_name>\S+)'

Rerun script.

Another note you'll need to manually check your migrated inputs, if you used either:

  • interval = auto
  • interval = 24h

instead of a cron, those will import, but continue to fail until you manually edit them (similar to how you manually edit the lookups).
