Need to debug if data is sent from a satelite to your master? Use an event stream to filter for CheckResults from hosts matching *foo*:

curl -N -k -s -u 'x:y' \
  -H 'Accept: application/json' \
  -X POST \
  'https://localhost:5665/v1/events?queue=more&types=CheckResult&filter=match%28%22*foo*%22,event.host%29'

The parameter for filter is match=("*foo*",event.host) urlencoded.
