BOINC and SETI@Home Data Output with Conky

Since my previous article about Conky, Conky on Ubunty 64 Bit – .conkyrc, I’ve been playing around with trying to get Conky to output some BOINC (SETI@Home data), and through a little digging, found a couple of very useful resources. The first being BOINC’s own client_status.xml file, located on Ubunutu in /var/lib/boinc-client/client_status.xml, which contains a lot of information about BOINC projects, Work Units, Status and so on. The second being a command line application, again built into BOINC – boinc_cmd. boinc_cmd can be executed with a bunch of parameters, such as –get_simple_gui_info and –get_project_status which output to the Terminal a lot of information about Projects and Work Units.

To output BOINC data via Conky, it’s possible to call the boinc_cmd in .conkyrc and strip down the information with grep and sed etc:

${execi 10 boinc_cmd --get_simple_gui_info | grep -m 1 "fraction done:" | tail -n 1 - | sed -e 's/ fraction done: //'}
${execi 10 boinc_cmd --get_simple_gui_info | grep -m 2 "fraction done:" | tail -n 1 - | sed -e 's/ fraction done: //'}

…and so on for each piece of data required for output, but this is pretty labourious, and makes for a rather ugly .conkyrc, so I’ve written a really quick and dirty Perl Script (it’s not pleasant to look at, and needs a LOT of work, so it’s more of a pre Alpha-Alpha! I’m not sure how, or if it will work with multiple projects, since I only have SETI@HOME installed…) – which actually retrieves all the data from the client_status.xml file. The (archived) script, boinc.pl can be downloaded here (and viewed below – just copy and paste the text into a file, and save it as “boinc.pl” if the download doesn’t work for you). It’s also posted over at the Ubuntu Forums. I’ve called it in .conkyrc by adding one simple line:

BOINC:
${color lightgrey}${execi 10 perl ~/ConkyScripts/boinc/boinc.pl}

OK, so that’s actually two lines, but the first line doesn’t really do anything except output the text “BOINC:” to Conky, so it doesn’t count – but it’s much cleaner than potentially dozens of lines, right? The script itself is in my ~/ConkyScripts/boinc directory and has been made executable:

sudo chmod a+x boinc.pl

Here’s the script so far – it’s VERY much Work In Progress, but it outputs the data as shown in the image above:

Edit 15/03/08: I’ve updated the code, so hopefully it’ll work with multiple projects:
