When hitting an issue you / Datadog support might need more logging from the Datadog agent to investigate on the possible causes.
To enable the full debug mode:
- modify your local datadog.conf (see this page to locate this configuration file on your instance)
- replace "# log_level: INFO" with "log_level: DEBUG" (make sure to get rid of # to uncomment the line)
- restart your datadog agent (see that page to find the restart command depending on your OS)
- wait a few minutes to generate some logs
Look here to find the location of the logs.
