Hello,

Is it possible to set telemetrylimit to under an hour?

Thanks!

Hello,

No. Why would you want to?

Primarily because the profiler client becomes extremely unusable to the point where it becomes unusable (presumably because of the number of threads for which 1h of accumulated telemetry is too large).

Could you please explain the problem in detail. It would be great if you could share the snapshot file demonstrating the problem. You may send it to support@yourkit.com

Hi Anton.

The problem occurs when we profile remotely using libyjpagent.so

We are starting the remote VM with:
-agentpath:/path/to/libyjpagent.so=delay=60000,sessionname=app-server

When we connect the profiler client (running from a Windows 10 PC) and select the Threads tab, then it becomes sluggish almost immediately. E.g. when trying to move the scrollbars it takes around 10 seconds for the UI to react.

Our initial idea was to try to reduce the history threshold, as it seems the client is overwhelmed by the amount to telemetry it ingest. Please let us know if there are any other avenues worth exploring.

Thanks!

- Open "Threads" tab and capture CPU snapshot when UI becomes slow and unresponsive.

- Please send captured snapshot to support(at)yourkit.com

Without the snapshot which reproduces the problem we cannot move forward.
