Following the latest announcements regarding log4j vulnerabilities, we have updated our Elastic platform from 7.16.0 to 7.16.1.
Just after this update, Elasticsearch failed to index anything.... be it data coming from logstash or internal Elasticsearch logging.
I've upgraded a test cluster from 7.15.1 to 7.16.1 and it is working fine for me. I'd recommend checking the logs of the cluster to see what is happening.
