we have slaves that are disabled which take jobs- that isn't good we have reports that we could ignore if the slave is already disabled I don't know how to get this specific information, I suspect we could get it after the page has loaded via a json request to another server.

how can we get a slave status (enabled/disabled) programatically?

The slave health page (https://secure.pub.build.mozilla.org/builddata/reports/slave_health/slave.html?name=tst-linux32-ec2-123) makes a bunch of calls to fetch things like this dynamically - you can probably steal a bunch of the js from there, or else just use: https://secure.pub.build.mozilla.org/slavealloc/api/slaves/tst-linux32-ec2-123?byname=1 etc :-)

We're planning to move this functionality to Treeherder anyway (Bug 1071152) so there is no point in fixing it here.
