[FLINK-2357] Add the new web dashboard and monitoring REST API
This pull request adds two new big features: The monitoring REST API and
the web dashboard.
It is joint work by @iampeter and me (although @iampeter did all the
stellar UI wonders, kudos!)
## Web dashboard
The web dashboard is a frontend implemented against the monitoring REST API
(see below). Compared to the old web frontend:
- It combines views about optimizer plan, runtime dataflow, details about
vertices and subtasks
- Has better overview pages that show more information at a glance
- Shows updating metrics (records, bytes)
- Shows updating user accumulators
- Timeline decoupled from online-only library
- Shows more information about status, exceptions, config
- Is more structured and maintainable
- Has a nicer design (personal opinion)
Here is are some teaser screenshots, showing the overview, job dataflow
view, and timeline. Clicking on the nodes shows the details about subtasks, etc.
To try it out, make sure you have this entry in the `conf/flink-conf.yaml`
file: `jobmanager.new-web-frontend: true`
The dashboard is not complete, yet, it lacks for example TaskManager
details and log file access.
Before removing the old web frontend, these missing aspects need to be
added.
## Monitoring API
The monitoring API is a REST API that allows you to issue HTTP requests
like `http://jobmanager:8081/jobs/7684be6004e4e955c2a558a9bc463f65` to query
the status of jobs. The responses are JSON encoded.
It is used by the web dashboard, but can be used to realize custom
monitoring tools.
There is a detailed doc describing the capabilities
(`docs/internals/monitoring_rest_api.md`), here is a summary list of supported
requests:
- `/config`
- `/overview`
- `/jobs`
- `/joboverview`
- `/joboverview/running`
- `/joboverview/completed`
- `/jobs/<jobid>`
- `/jobs/<jobid>/config`
- `/jobs/<jobid>/exceptions`
- `/jobs/<jobid>/accumulators`
- `/jobs/<jobid>/vertices`
- `/jobs/<jobid>/vertices/<vertexid>`
- `/jobs/<jobid>/vertices/<vertexid>/subtasktimes`
- `/jobs/<jobid>/vertices/<vertexid>/accumulators`
- `/jobs/<jobid>/vertices/<vertexid>/subtasks/accumulators`
- `/jobs/<jobid>/vertices/<vertexid>/subtasks/<subtasknum>`
-
`/jobs/<jobid>/vertices/<vertexid>/subtasks/<subtasknum>/attempts/<attempt>`
-
`/jobs/<jobid>/vertices/<vertexid>/subtasks/<subtasknum>/attempts/<attempt>/accumulators`
- `/jobs/<jobid>/plan`

The change breaks the functionality by returning incorrect HTTP responses
(length / contents mismatch).

> New JobManager Runtime Web Frontend
> -----------------------------------
>
> Key: FLINK-2357
> URL: https://issues.apache.org/jira/browse/FLINK-2357
> Project: Flink
> Issue Type: New Feature
> Components: Webfrontend
> Affects Versions: 0.10
> Reporter: Stephan Ewen
> Attachments: Webfrontend Mockup.pdf
>
>
> We need to improve rework the Job Manager Web Frontend.
> The current web frontend is limited and has a lot of design issues
> - It does not display and progress while operators are running. This is
> especially problematic for streaming jobs
> - It has no graph representation of the data flows
> - it does not allow to look into execution attempts
> - it has no hook to deal with the upcoming live accumulators
> - The architecture is not very modular/extensible
> I propose to add a new JobManager web frontend:
> - Based on Netty HTTP (very lightweight)
> - Using rest-style URLs for jobs and vertices
> - integrating the D3 graph renderer of the previews with the runtime monitor
> - with details on execution attempts
> - first class visualization of records processed and bytes processed
