How to check connectivity status with Python API

fabien.marcaillou

Hi,

I'd like to know how I can check the connectivity status with the refinitiv.data Python API (through the platform deployed connection)?

Can I also set timeout with call like this?

Thank you for your help.

Hi @fabien.marcaillou

You can check the EX-4.01.01-Sessions.ipynb example in Example.DataLibrary.Python/Examples /4-Session/ GitHub repository.

Example Code:

session = rd.session.platform.Definition(
    app_key = APP_KEY, 
    deployed_platform_host = 'localhost',
    deployed_platform_username = '<My DACS Username>'
).get_session()
session.open()
print(session.open_state) #OpenState.Opened

Result when testing with my local RTDS server:

I hope this information helps.

Hi
@wasin.w ,

Thank you for your suggestion, I already tried it but it's not giving a reliable state.

For testing purpose i've closed my proxy (to be disconnected from the ATS) however it still giving me an "Opened" state.

Do you have an alternative solution?

Hello @fabien.marcaillou

Thank you for the information. Does your deployment scenario look like the following diagram?

If so, please be informed that the library can detect a connection status with its upstream (ADS) only, not the source/feed like ATS, ADH, or other OMM IProviders.

As long as a connection between the library and ADS is still fine, the session.open_state code always returns "Opened".
