HTTP endpoints¶

A subset of the following pages will be available from the scheduler or workers of a running cluster. The list of currently available endpoins can be found by examining /sitemap.json.

Main dashboard links¶

Dynamic bokeh pages. The root redirects to /status, and each page links to the others via a header navbar.

/status: entry point to the dashboards, shows cluster-wide memory and tasks
/workers: currently connected workers and their CPU/memory usage
/tasks: task block view with longer look-back than on /status
/system: global stats for the cluster, CPU, memory, bandwidth, file descriptors
/profile: flamegraph statistical profiling across the cluster
/graph: currently processing graphs in a dependnecy tree view
/info: redirect to /info/main/workers.html

Scheduler HTTP¶

Pages and JSON endpoints served by the scheduler

/health: check server is alive
/info/main/workers.html basic info about workers and links to their dashboards and logs
info/worker/(worker).html: more detail about given worker, keyed by TCP address; links to tasks
info/task/(task).html: details about a task on the cluster, by dask key; links to worker,
related tasks, and client
/info/call-stacks/(worker).html: tasks currently handled by given worker
/info/call-stack/(task).html: state of task (where it is running)
/info/main/logs.html: scheduler logs
/info/logs/(worker).html: logs of given worker
/individual-plots.json: map of path to description for available individual
(i.e,. one-pane, non-dashboard) plots
/eventstream: scheduler events on a websocket
``/proxy/(port)/(address)/(path): proxy to worker HTTP locations
(if you have jupyter-server-proxy)
/metrics: prometheus endpoint
/json/counts.json: cluster count stats
/json/identity.json: scheduler information
/json/index.html: link to the above two endpoints
/sitemap.json: list of available endpoints
/statics/(): static file content (CSS, etc)
/stealing: worker occupancy metrics, to evaluate task stealing
