Getting the list of active processes through API

Hi

I am writing an application in .NET (C#) that monitors applications/database tiers and can correlate events between them.

I am looking for a good way to extract the list of active processes in the SAP on a regular interval so I can enrich my dashboard with SAP oriented transactions information.

for example - the information in tcode SM50 where you can see all transactions/processes.

Is there a good and efficient way to extract this information thorough API every few seconds ?

IF so - can you redirect me to the documentation around it ?

thanks.
