Hi, I already configure apache metron using hcp 1.7.1 with ambari 2.6.2 on bare metal (single node) os centos 7. The problem was the alert UI page does not working properly. There are data on the alert UI page but contains error log file "metron-rest.log". nested: IllegalStateException[[nested] failed to find nested object under path [metron_alert] The parser used suricata 'eve.json' file, that load into nifi and from nifi to kafka. The topology on storm are created the parser used ' JSONMap '. Based on error on log file, that nested on elasticsearch indexing. After follow this link https://metron.apache.org/current-book/metron-platform/metron-elasticsearch/index.html It solved the issue temporarily, but the error comes up again when elasticsearch create new index. Did i need create a template for solve this issue or any other fix? Thanks. ... View more
