Creating Kibana Apps Install it npm install -g yo # Install yeoman npm install -g generator-kibana-plugin # Install the kibana plugin generator Configure it mkdir my-new-plugin cd my-new-plugin yo kibana-plugin # Generate an app skeleton npm start # Start the plugin development environment Create it cd ../kibana npm start # With Elasticsearch running, start the kibana development environment Visit http://localhost:5601
16 What to talk about • customisable colours and labels • strong integration with security • The dark side is back • space efficiency up 20% => more real estate • export all the things! • plugin all the things! • kibana app’s [ and generator ] • status page Kibana Source: Gray Arial 10pt
What is the current Logstash throughput? 20 Logstash is blocked?, ask for a hot threads dump. Worried about OOM? ask for memory consumption. Broken by plugin instance. Per instance and node. to be continued……
Web API resources • Current web api resources: • http://localhost:9600/_node/hot_threads • http://localhost:9600/_node/stats/ • http://localhost:9600/_node/stats/events • http://localhost:9600/_stats/jvm • http://localhost:9600/_plugins/ • ….. 21
Step 1: Config Reloading Previously: Any config change made to file required a process restart Feedback loop for development/ testing slow Processing pipeline must be long living 25 File watched for changes or SIGHUP triggers reload Current Pipeline stopped Config Validated New Pipeline started - no process restart Why? How?
The java reincarnation • Logstash is based on JRuby, Ruby on top of the JVM • Some core components are being rewritten in plain java. • First step: the event representation. • Introduced in 2.3.0, reverted in 2.3.1, on track for 5.0. • Provide the foundations for upcoming persistence queues, this change will be backwards due to the nice introp between JRuby and Java. • Will enable not just ruby plugins, but using any JVM languages • And not only about this, but performance ….. 28
This that might break up for 5.0 • New Event API proposal [#5141] • bin/plugin is now bin/logstash-plugin [#4871] • Require Java 8 as default [#3877] • Fieldref StringInterpolation and Fixnum/Float values [#5114] • Add support for x-pack’s [#4872] • Runner cleanup [#3148, #3860] • Use settings file to complement command line arguments [#4401] 34
