= Server status =

Each project should export its server status in two forms:

 * '''URL/server_status.php:''' human-readable (web page).
 * '''URL/server_status.php?xml=1:''' XML format, as follows:
{{{
<server_status>
    <update_time>1127772607</update_time>
    <daemon_status>
        <daemon>
            <host>jocelyn</host>
            <command>BOINC database</command>
            <status>running</status>
        </daemon>
        <daemon>
            <host>castelli</host>
            <command>master science database</command>
            <status>running</status>
        </daemon>
        <daemon>
            <host>kryten</host>
            <command>sah_validate4</command>
            <status>running</status>
        </daemon>
        ...
    </daemon_status>
    <database_file_states>
        <results_ready_to_send>563389</results_ready_to_send>
        <results_in_progress>1198237</results_in_progress>
        <workunits_waiting_for_validation>19</workunits_waiting_for_validation>
        <workunits_waiting_for_assimilation>16</workunits_waiting_for_assimilation>
        <workunits_waiting_for_deletion>0</workunits_waiting_for_deletion>
        <results_waiting_for_deletion>0</results_waiting_for_deletion>
        <transitioner_backlog_hours>-0.0002777</transitioner_backlog_hours>
    </database_file_states>
</server_status>
}}}

There are two ways to do this:

 1. Copy the file `server_status.php` from `html/ops` to `html/user`. This works fine as long as you don't need any customization, and the DB queries in the page only take a few seconds (the page is cached, so they are done infrequently).
 1. Write a periodic script that generates the 2 pages as files, and put a script in `user/server_status.php` that echoes one file or the other.
