I'm deploying an scenario with ES 5.5.2 and Dynatrace. I'm using PureLytics to send the info to elasticsearch with the dynamic template in order to avoid the timestamp failure.
The integration works, I can get the info through Kibana but I have noticed there are some fields missing like "ipAddress". The field is acknowledged in the index composition but it is never written. Looking the same events in dynatrace, ipAddress is indeed written.
Maybe this is happening with more fields too, but the first field I have noticed is ipAddress
