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