Do anything from tracking query load to understanding the way requests flow through your apps. URL Kibana vs Grafana # ref Kibana # Kibana is useful to convert log data from the ELK stack into visualizations and it also supports querying logs. Grafana # Grafana is more of a general-purpose visualization tool that can work with a handful of data sets that may or may not be “logs”.https://jaaved.netlify.app/notes/elastic_licenses--20220206-101226/Mon, 04 Apr 2022 10:31:34 +0300https://jaaved.netlify.app/notes/elastic_licenses--20220206-101226/# ECK works on two licenses: basic and enterprise. At KFUPM we purchased platinum license, there we cannot use ECK, forced to upgrade the existing Virtual Machine based nodes. How charges for licenses? # They charge per node basis. Each license type has it own definition about what a node is. E.g. in platinum a machine with 64GB RAM is a node. Platinum vs Enterprise licenses ATTACH # To purchase platinum license minimum 3 nodes should be purchased and for enterprise license minimum of 6 nodes should be purchased.
