2.12 Maintenance

The buildmaster can be configured to send out email notifications when a slave has been offline for a while. Be sure to configure the buildmaster with a contact email address for each slave so these notifications are sent to someone who can bring it back online.

If you find you can no longer provide a buildslave to the project, please let the project admins know, so they can put out a call for a replacement.

The Buildbot records status and logs output continually, each time a build is performed. The status tends to be small, but the build logs can become quite large. Each build and log are recorded in a separate file, arranged hierarchically under the buildmaster's base directory. To prevent these files from growing without bound, you should periodically delete old build logs. A simple cron job to delete anything older than, say, two weeks should do the job. The only trick is to leave the buildbot.tac and other support files alone, for which find's -mindepth argument helps skip everything in the top directory. You can use something like the following:

     @weekly cd BASEDIR && find . -mindepth 2 -ipath './public_html/*' -prune -o -type f -mtime +14 -exec rm {} \;
     @weekly cd BASEDIR && find twistd.log* -mtime +14 -exec rm {} \;

Alternatively, you can configure a maximum number of old logs to be kept using the --log-count command line option when running buildbot create-slave or buildbot create-master.
