I have a java log with some entries having stacktraces. I'm using the multiline option in filebeat and a grok filter in logstash with the pattern ending in GREEDYDATA, i.e.:
This works fine with logmessage sometimes having up to 100 lines though. In Kibana's Discover tab I see the whole stacktrace but in visualizations they appear empty, as if there was no data in that field. Could this be caused by a maximum field length in Kibana visualizations? I'm using version 4.4.0.
