@snehapar9 Is the dashboard not updating with new traces, or has the number stopped at 10k? The number stopping at 10k is expected, as that's the in-memory limit. At that point, old traces are removed as new traces are added.

Continuing to increase the number without the data isn't technically possible.

It seems like the problem is that the user thinks telemetry is no longer updating. What about adding an indication somewhere to the UI that the memory limit has been reached and old traces are being removed?
