Project statistics data

Projects export statistics data in XML-format files. Most projects regenerate the files every 24 hours. These files are contained in a download directory, usually PROJECT_URL/stats/.

The download directory contains the following files:

tables.xml
This gives the total number of records for each entity type (team, user, and host). It also includes the UNIX time when the files were last generated, and a list of the project's applications, with counts of various things. For example:
<tables>
    <update_time>1046220857</update_time>
    <nusers>127</nusers>
    <nteams>14</nteams>
    <nhosts>681</nhosts>
    <total_credit>1234.234</total_credit>
    <applications>
        <application>
            <name>setiathome</name>
            <results_unsent>100</results_unsent>
            <results_in_progress>1000</results_in_progress>
            <results_over>10000</results_over>
        </application>
        ...
    </applications>
</tables>
host.gz
List of hosts
team.gz
List of teams
user.gz
List of users

The format of the various XML elements in the output files is as follows. Notes:

  • <cpid> ('cross-project identifier?') is a unique identifier across multiple projects. Accounts with the same email address on different projects will have the same cross-project identifier (as long as at least one computer is attached to both accounts).
  • All 'expavg_credit' values were computed at some point in the past (given by 'expavg_time'). To compute their current values, they must be scaled according to the RAC decay formula.
  • Text fields may contain XML entities. If you aren't using a real XML parser, you need to decode the entities yourself.
