I guess I should add for clarity, there are a couple of .json files related to Maddash that you could be referring to.  

My instructions assume you are looking for the PSconfig template (also referred to as the "Mesh Config file").  That's the file that sets up a mesh of tests between multiple hosts.  It is most often being served up by a web server so that it is accessible (via a GET request) from the testing nodes on a regular basis.  Assuming you know which host was serving up that file to your testing nodes, and the file still resides there, I would run the commands I provided on that host.

Sincerely,

Kate, 

     It really is hard to tell where it might be located since the administrator can put it just about anywhere on the system, and then tell Apache to serve up that directory/file to the web for distribution to testing nodes.  All of my nodes (installed with the toolkit bundle) have the linux "locate" command available on them, yours likely do too.  I'd try two commands:

sudo updatedb    (to update the locate database) 

locate */html/*.json    (to look for any .json files contained within the default "html" directory that apache seems to operate within on these installs).

You'll get (hopefully) a small-ish list of .json files that are potential candidates.

Hello All,

We have an old version of maddash installed.  No documentation about how the system was configured exists.  How do we find the json file with the tests that are being run?

Thanks for any insights.

Kate
