SDN Sample Application

[stephshaf]

Hello,

I have been following the HP VAN SDN Controller Programming Guide to create the sample application "health-monitor". In the guide it says that the complete sample application source code can be found in the HP VAN SDN Controller SDK. I have searched through the hp-sdn-sdk-2.0.0 folder that I recieved from HP and have been unable to find it. Can you point me in the right direction?

Thanks,

Stephanie

Hello Stephanie,

Thanks for posting your query.

You can follow below steps to get the code of sample application health-monitor -

 1. Unzip hp-sdn-sdk-2.0.0.zip

2. Under bin directory you can find installer-sdk script, just run this script without any argument.

3. Then run gen-sdn-app script (which is also under bin directory) without any argument. This will show the sample usage at the bottom of the screen.

4. Run the gen-sdn-app with arguments as mentioned in the sample usage. This will generate the code for the sample application.

You can take help from SDN Programming guide [page 8 - HP Van SDN Controller SDK and page 113 onwards- Application Generator (Automatic Workspace Creation) ].

Please let us know if you still face the problem.

Thanks,

I used the steps as mentioned above and a document with name "Sample Application Generation and Installation" but still it says the error as "gen-sdn-app: command not found"...

I was able install the SDK and later got stuck with this. Please help.

ankur@ankur-comp2:~$ cd /media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0/
ankur@ankur-comp2:/media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0$ gen-sdn-app ~sdn-hm mango DeviceHealth "Device Health Monitor" "Mango Agile Networks" "Application for monitoring health of network devices." health
gen-sdn-app: command not found

Thanks in advance.

Hi Ankur,

As you mentioned that you were able to install the SDK , so please make sure that  you have the gen-sdn-app script in the same directory (i.e.  under hp-sdn-sdk-2.0.0/bin)

gen-sdn-app script is in bin directory while you are trying to run this script from hp-sdn-sdk-2.0.0 directory so you get the error “gen-sdn-app: command not found”

Also please check if your PATH variable has  dot (.) to search in the current directory.

If PATH variable has dot, you can run as below from the bin directory -

/media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0/bin$ gen-sdn-app

If PATH variable does not have a dot , you have to run as below-

/media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0/bin$ ./gen-sdn-app

Please  let us know if you still face the issue.

Thanks,

The best solution is to make sure PATH has the path to the script/executable:

/media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0/bin

Hi Ankur,

You are missing one argument (i.e. hm) while running the gen-sdn-app script.

Please include hm as below while running the script -

ankur@ankur-comp2:/media/sf_SDN/1VANcontroller/hp-sdn-sdk-2.0.0/bin$ gen-sdn-app ~/sdn-hm/ hm mango DeviceHealth "Device Health Monitor" "Mango Agile Networks" "Application for monitoring health of network devices." health

Please follow the commands/steps as per the guide/reference docs and you will be able to successfully build the sample app.

Please  let us know if you still face the issue.
