What will hapen if elasticsearch or mongodb down when I upgrade es/mongodb

My graylog is using a elasticsearch cluster, and I want to add a backup plugin in es, but it requires restart es. And I also want to update mongodb to a cluster, this will have downtime for mongodb.
May I know if it will disturb log collection if elasticsearch (or mongodb) down for about 10 minute or less?


you can disable processing in Graylog when you do the Elasticsearch Upgrade/Reboot what will buffer the messages in the Graylog journal.

How long that is possible depends on your ingest rate and the configured journal size.

When you upgrade/reboot MongoDB you must stop Graylog before as it is essential for Graylog that MongoDB is running and accessible.
