Graylog is an integrated log capture and analysis solution for operational intelligence.

Non Graylog-authored components include MongoDB for metadata and Elasticsearch for log file storage and text search.

Messages (logs) are only stored in Elasticsearch. If we have data loss on Elasticsearch, the messages are gone.

MongoDB is only storing meta information and will be abstracted with a general database layer in future versions. This will allow you to use other databases like MySQL instead.
