类 HistoryServer

java.lang.Object

org.apache.flink.runtime.webmonitor.history.HistoryServer

public class HistoryServer
extends Object

The HistoryServer provides a WebInterface and REST API to retrieve information about finished jobs for which the JobManager may have already shut down.

The HistoryServer regularly checks a set of directories for job archives created by the FsJobArchivist and caches these in a local directory. See HistoryServerArchiveFetcher.

All configuration options are defined inHistoryServerOptions.

The WebInterface only displays the "Completed Jobs" page.

The REST API is limited to

• /config
• /joboverview
• /jobs/:jobid/*

and relies on static files that are served by the HistoryServerStaticFileServerHandler.
