OMEGAMON Data Connect fails due to unknown configuration parameters

Symptoms

The OMEGAMON® Data Connect log contains the following message reporting an unknown configuration parameter (Property … unbound):
APPLICATION FAILED TO START
…
Property: <dotted_key>
…
Reason: The elements [<dotted_key>,<dotted_key2>,…] were left unbound

Causes

The OMEGAMON Data Connect configuration file contains one or more parameters that are unknown in the context in which they are specified.

The parameters might be misspelled or incorrectly indented.

An example of incorrect indenting:

connect:
  output:
    stdout:
    enabled: true # Incorrectly indented

It's likely that these parameters were intended to enable output to STDOUT. Instead, they cause the problem described here, because the enabled key is unknown at the same indent level as stdout. In the context of these parameters, enabled should be indented as a child of stdout.

Resolving the problem

  1. Edit the configuration file to fix the problem.
  2. Use the OMEGAMON Data Provider configuration validator to validate the updated configuration file.
  3. Start OMEGAMON Data Connect.
