I'm using the Talend Open Studio Big Data 7.3 and I want to know if is possible to connect with the ELK stack from this open source version. I checked that the log4j is now available to the 7.3 version, and I think that is possible to connect the log4j directly to kibana. I've tried to perform this without success, maybe because I'm new with ELK stack. Can anyone provide some example for this? if it is possible...
