This PR adds UI for visualizing Logstash internal metrics with contributions from @ph, @jsvd and @pickypg
Changes include:
* x-pack component for Logstash which installs a monitoring exporter plugin to Logstash core. This periodically ships
monitoring data to the monitoring bulk API endpoint.
* Adds xpack.monitoring.* setting to logstash.yml when x-pack is installed.
* UI changes to graph Logstash monitoring data. Logstash processes are called nodes. They send separate monitoring info
which gets aggregated and displayed at cluster level and also at individual node level.
* Adds gradle build support for Logstash x-pack which can be controled via `xpack.logstash.build=false`
Fixeselastic/elasticsearch#4169
Original commit: elastic/x-pack-elasticsearch@f58ef406c1
* Update readme to reflect new dev setup directory structure.
* Fix typo in elasticsearch-extra path in readme
* Update gradle exception for x-pack directory structure.
* Make directory path where x-pack must be checked out explicit in the gradle exception
Original commit: elastic/x-pack-elasticsearch@91f1d04542
This change removes the project attachment support, and instead relies
on x-plugins being checked out under extra-plugins/x-plugins within an
elasticsearch checkout. The only real change, other than removing
unnecessary code, was to rename the license/core project because gradle
project substitution has a bug which causes it to try and use ES core as
the substitution. (Unfortunately this is not reproduceable with a simple
example, so I have not yet filed an issue with gradle).
