Figure 13.3. Viewing disk usage
This list is sorted by overall disk usage, so the projects using the most disk space are at the top. The list
provides two values for each project—the Builds column indicates the total amount of space used by
all of the project’s build history, whereas the Workspace column is the amount of space used to build
the project. For ongoing projects, the Workspace value tends to be relatively stable (a project needs
what it needs to build correctly), whereas the Builds column will increase over time, sometimes at a
dramatic rate, unless you do something about it. You can keep the space needed by a project’s history
under control by limiting the number of builds being kept for a project, and by being careful about what
artifacts are being stored.
To get an idea of how fast the disk space is being used up, you can also display the amount of disk space
used in each project over time. To do this, you need to activate the plugin in the System Configuration
screen (see Figure 13.4, “Displaying disk usage for a project”).
Figure 13.4. Displaying disk usage for a project
This will record and display how much space your projects are using over time. The Disk Usage plugin
displays a graph of disk usage over time (see Figure 13.5, “Displaying project disk usage over time”),
which can give you a great view of how fast your project is filling up the disk, or, on the contrary, if
the disk usage is stable over time.
