v0.20.5

Added

• Adds a new config option to lading_payload::dogstatsd::Config,
  length_prefix_framed. If this option is on, each "block" emitted by the
  dogstatsd generator will have a little-endian u32 prefix (4 bytes) containing
  the length of the following block.

Fixed

• Total CPU calculation routine no longer panics in some scenarios
• Fixes bug with retry logic in both unix-stream and tcp generators that could
  result in unexpected, extra connections.

v0.20.4

Added

• lading.running gauge metric that submits a value of 1 as long as the main
  select! of lading is executing.
• target.running gauge metric that submits a value of 1 as long as the target
  is running.

Changed

• Dogstatsd payload structs now have public fields.
• Capture file descriptor is flushed as soon as current lines are written.
• Renamed Shutdown data type to Phase so that this data type can be used as
  a signal to control lading behavior over distinct stages of load generation
  (e.g., warmup, shutdown).
• Prometheus telemetry and Go expvar target metrics are no longer emitted during
  lading's warmup ("experimental") phase.

Fixed

• Refactors the main select! in lading/src/bin/lading.rs to loop over the
  select to address a potential early-termination bug when the set of generators
  are empty.

v0.20.4-rc1

v0.20.4-rc1

v0.20.3

Added

• ProcFs generator is now suitable for use.

v0.20.3-rc1

Changed

• ProcFs generator now allows files to be copied from host verbatim.

v0.20.3-rc0

Added

• ProcFs generator is now suitable for use.

v0.20.2

Fixed

• Process gauges will now be zeroed before iteration. This prevents values from
  exited processes from being reported.

Changed

• Lading now aborts on panic.
• The shutdown mechanism has been adjusted to improve its reliability.
• The capture manager now runs on a background OS thread.

Added

• Added metrics that report CPU and memory usage of the whole target process tree.

v0.20.2-rc1

Added

• Added captures to tally CPU and memory usage of the whole target process tree

v0.20.1

Changed

• Internal shutdown sequence is now changed to an advisory signal. There is no
  user-facing change.
• Disabled ANSI codes in logging.

Fixed

• Removed generational storage in capture management, resolving a runtime hang.

v0.20.1-rc4

Added

• We now have optional support for tokio-console for debugging purposes.

Changed

• Remove generational storage in metrics to avoid contended RWLock.
