Hey @Garvit-77!
All the commits must be signed in order to pass the DCO check of the GitHub.

[yurishkuro]

Signed commits is not the concern for me here - the PR itself is meaningless, it just deletes two files. I wouldn't open an issue if the problem was with deleting two files.

[Garvit-77]

I Absolutely get that and to solve the issue Even i wasn't Deleting two files, rather just changed the endpoints for the function
GetSamplingRate to sample the collector .
I will check what went wrong and raise another pr
Thank You.
