Exposing/Extending an OpenStack specific command

[Leander]

Hello all,

I'm currently using version 1.5.2 and was wondering how I could expose (or extend in case it does not exist) the diagnostics command in the OpenStack driver: 

[API_ENDPOINT]/v2/[TENANT]/servers/[SERVER_ID]/diagnostics? 

What would be the best place to implement this, in case the command implemented?

Regards,

Leander

Probably more a jclouds-dev question.

Is the command only for servers? Do you have a doc link?

If only for servers, update classes: ServerApi ServerAsyncApi ServerApiExpectTest ServerApiLiveTest

Cheers,
-A

Sorry about that, shall direct it to the appropriate list next time.  Thanks for the suggestions, I shall look into to those. There is no doc link, as far as I know of, I've retrieved the link by using the python command line tool with the --debug option for the command diagnostics. This command should work with OpenStack Folsom using the Xen API and libvirt ( more hypervisors might support this, although I'm not sure).

[Adrian Cole]

Cool.  While you are on it, you mind pasting what the debug output is?  I'm curious.

Since i'm using Essex at the moment, the command doesn't work. The only output it produces is below. If you want to check the output of this command, you can find a sample of Xen and libvirt in this commit log https://github.com/openstack/nova/commit/ad54ed53cf6a475ad0f8042f8b95454a8c0b35a4

I've found the ServerAPI file under ./jclouds/apis/openstack-nova/src/main/java/org/jclouds/openstack/nova/v2_0/features/ServerApi.java. Any pointers on how to compile changes using the eclipse setup and using JClouds REST API?
