Tornado Communication over NATS

Until the NetEye 4.10 release, the Tornado module inside NetEye handled communications between its components (the Tornado Collectors and the Tornado Engine) via direct, clear-text TCP connections. On local systems, this configuration does not represent a limitation, since in this case there is no requirement to verify the identity of the peer (it is always…

Support for Elasticsearch-only Nodes

Until NetEye 4.8, customers who needed to expand the capacity of their Elasticsearch cluster running alongside their Red Hat cluster could add new standard nodes to NetEye clusters.
