    v1 v1  
     1== Config Server API ==
     2
     3The config server is a RESTful API. The server (by default) listens on port 5000. All messages are in JSON and have a top level {{{status}}} entry. If {{{status}}} is not zero, the only other entry in the message will be a {{{message}}} field, which contains an error message. Otherwise the message will contain the information requested.
     4
     5* URL: **/this_is_a_bad_URL**. Bad URLs return a non-zero {{{status}}} and {{{error}}} message.
     6  * Example: unknown URL:
     7{{{
     8> curl http://localhost:5000/borkborkbork
     9{
     10  "message": "404: Not Found",
     11  "status": 1
     12}
     13}}}
     14  * Example: Bad request. A valid URL, but with bad "arguments".
     15{{{
     16> curl http://localhost:5000/user/jjh
     17{
     18  "message": "user jjh not found",
     19  "status": 1
     20}
     21}}}
     22  * And another Invalid request.
     23{{{
     24> curl http://localhost:5000/computer/bork
     25{
     26  "message": "No computer 'bork' found.",
     27  "status": 1
     28}
     29}}}
     30
     31* URL: **/pnodes**. Return names of all physical nodes in the experiment. Each entry contains a {{{type}}}, {{{control_name}}}, and {{{exp_name}}} fields.
     32 * Example
     33{{{
     34> curl http://localhost:5000/computer/glory
     35{
     36  "pnodes": [
