New Features

  • Adds garbage collection runtime metrics.

    Records statistics as metrics after garbage collection sweeps. This feature is disabled by default and can be enabled and configured with these settings.

Improved Features

  • Improved CPU metric sampling.

    Adds separate metrics for user time, system time, and total time as well as utilization as a percentage for each.

  • Improved memory metric sampling.

    Adds memory utilization as a percentage, and adds PID to metrics to allow faceting in NRQL queries.

  • Increased custom attribute limit from 64 to 128.

    The custom attribute limit affects user added attributes on spans, events, and transactions.

Bug Fixes
