v3.8.0

Added

• Allows Rezolus to run on MacOS though sampler support is limited.
• Provides msgpack exposition format as a more efficient exposition format.

Fixed

• Updates of various direct dependencies.

v3.7.0

Added

• Optional compression for HTTP exposition. (#128)
• Additional GPU metrics for utilization and energy consumption. (#138)

Fixed

• Duplicate metric name in Rezolus sampler. (#134)

v3.6.1

Fixed

• Fixed incorrect type annotation for CPU metrics (frequency, ipkc, ipus). (#98)
• Fixed under-reported TCP retransmits. (#121)
• Fixed TCP segment metrics. (#123)

v3.6.0

Added

• Allow configuration of individual samplers in the config file. This allows
  each sampler to be individually enabled/disabled and have its collection
  intervals adjusted.
• TCP connection state sampler which tracks the number of tcp connections in
  each state.
• Rezolus sampler which monitors resource utilization of Rezolus itself.
• Optional exposition of histogram buckets on the Prometheus/OpenTelemetry
  endpoint.
• Track latencies for each group of syscalls to help understand the breakdown of
  total syscall latency.

Fixed

• Corrected a length check of the mmap'd histogram regions. This fix enables the
  fast path for reading histogram data into userspace.

v3.5.0

Changed

• Updated metriken and replaced heatmaps with histograms. This reduces runtime
  resource utilization.

v3.4.0

Changed

• Moved to fetching multiple percentiles at once to reduce overhead.
• Refactor of the hardware info sampler into a separate crate to allow reuse and
  make improvements to that sampler.

Fixed

• Update warp to address RUSTSEC-2023-0065.

v3.3.3

Added

• Packaging support for aarch64

Fixed

• Updated dependencies to pull-in fixes and improvements.

v3.3.2

Fixed

• Fixed hardware info and cpu samplers on platforms which do not expose either
  die or node information in the topology, which may happen on ARM.
• Fixed BPF program generation to restore compatibility with clang 11.

v3.3.1

Fixed

• Fixed path inconsistency in Debian packaging.

v3.3.0

Added

• Added BTF type definitions for aarch64 target architecture.

Fixed

• Update dependencies to reduce overhead and pull-in bugfixes.
• Documentation improvements.
