 Data streamed by a Kafka Connector will be converted to a RADAR-base oriented output directory, by organizing it by project, user and collection date.
 It supports data written by [RADAR S3 sink connector](https://github.com/RADAR-base/RADAR-S3-Connector) is streamed to files based on topic name only. This package transforms that output to a local directory structure as follows: `projectId/userId/topic/date_hour.csv`. The date and hour are extracted from the `time` field of each record, and is formatted in UTC time.

 To run the output generator as a service that will regularly poll the source directory, add the `--service` flag and optionally the `--interval` flag to adjust the polling interval or use the corresponding configuration file parameters.
 
+## Sentry monitoring
+
+To enable Sentry monitoring:
+
+1. Set a `SENTRY_DSN` environment variable that points to the desired Sentry DSN.
+2. (Optional) Set the `SENTRY_LOG_LEVEL` environment variable to control the minimum log level of events sent to Sentry.
+   The default log level for Sentry is `ERROR`. Possible values are `TRACE`, `DEBUG`, `INFO`, `WARN`, and `ERROR`.
+
+For further configuration of Sentry via environmental variables see [here](https://docs.sentry.io/platforms/java/configuration/#configuration-via-the-runtime-environment). For instance:
+
+```
+SENTRY_LOG_LEVEL: 'ERROR'
+SENTRY_DSN: 'https://000000000000.ingest.de.sentry.io/000000000000'
+SENTRY_ATTACHSTACKTRACE: true
+SENTRY_STACKTRACE_APP_PACKAGES: io.confluent.connect,org.radarbase.connect.rest
+```
