There are limitations in executing Git commands in order to save the server resource of Bitbucket Server (formally Stash). See Stash is reaching resource limits for more detail

  1. The maximum number of concurrent requests using git commands using the UI or REST services (e.g. git diff via the UI), which is configurable at throttle.resource.scm-command of stash-config.properties. Default value is 25.
  2. The maximum number of concurrent requests using "hosting" commands (e.g. git clone, push, pull), which is configurable at throttle.resource.scm-hosting of stash-config.propertiesDefault value is 1.5*cpu (1.5 times the number of available cpus/cores).

You may need to know how long your Git commands take and the number of concurrent Git commands available, in order for resource tuning purposes.

ソリューション

The following steps will enable Bitbucket Server to log the timestamp and the number of concurrent Git commands available when a Git commands is start/finish executing:

  1. Insert the following line into <configuration> tab block of <BBS_INSTALL_DIR>/atlassian-bitbucket/WEB-INF/classes/logback.xml (<STASH_INSTALL_DIR>/atlassian-stash/WEB-INF/classes/logback.xml for Stash)

    <logger name="com.atlassian.stash.internal.throttle.SemaphoreThrottleService" level="TRACE"/>
  2. Bitbucket Server を再起動する

  3. You will see logs similar to this in <BBS_HOME_DIR>/log/atlassian-bitbucket.log (<STASH_HOME_DIR>/log/atlassian-stash.log for Stash)

    2015-10-19 09:48:00,416 TRACE [http-nio-7990-exec-9] admin @1VAGN69x587x115x0 0:0:0:0:0:0:0:1 "POST /scm/proj/a-repository.git/git-receive-pack HTTP/1.1" c.a.s.i.t.SemaphoreThrottleService Released [scm-hosting] ticket (12/12)

    In this example, the Git hosting command took 45 seconds (= 09:48:00 - 09:47:15) and 11 more Git hosting commands were available when the command was executed.
