Fixed

• Fixes a panic in the signal mechanism that appeared when using the file
  generator most prominately.

v0.23.0

Added

• Added ability to create tags for both expvar and prometheus target metrics specific to a single target_metrics configuration (example below shows prometheus metrics collected from the core agent and two additional tags created)

  target_metrics:      
    - prometheus: #core agent telemetry
        uri: "http://127.0.0.1:5000/telemetry"
        tags:
          sub_agent: "core"
          any_label: "any-string-value"

v0.23.0-rc0

Added

• Added ability to create tags for both expvar and prometheus target metrics specific to a single target_metrics configuration (example below shows prometheus metrics collected from the core agent and two additional tags created)

  target_metrics:      
    - prometheus: #core agent telemetry
        uri: "http://127.0.0.1:5000/telemetry"
        tags:
          sub-agent: "core-agent"
          any-label: "any-string-value"

v0.22.0

Fixed

• Fixes bugs in smaps parsing code that can result in under-counting RSS in
  the smaps view of the data.
• Target observer was not exposed through CLI.

Changed

• Now built using rust 1.79.0

Added

• Target observer now allows a docker target, identified by name.
• Lading experiment duration may be set to (effectively) infinite via --experiment-duration-infinite.
• Allow lading to export prometheus over UDS socket.

v0.22.0-rc3

Added

• Retrieve memory, CPU information from cgroup controller for every pid observed on Linux.

v0.22.0-rc2

Added

• Incorporate perf-event telemetry on Linux for CPU data.

v0.22.0-rc1

Fixed

• Target observer was not exposed through CLI.

v0.22.0-rc0

Added

• Target observer now allows a docker target, identified by name.
• Lading experiment duration may be set to (effectively) infinite via --experiment-duration-infinite.
• Allow lading to export prometheus over UDS socket.

v0.21.1

Changed

• Added lading version to initial welcome print msg.

Fixed

• Prometheus metric exporter did not include some internal metrics (generator
  metrics)
• Range values in the dogstatsd payload will now generate the full inclusive
  range. Previously, values were generated up to but not including the max
  value.
• HTTP Blackhole now supports ZSTD encoded requests

v0.21.0

Changed

• Improved the block cache construction to better fill the pre-defined space.
• Removed streaming cache method. Fixed is now the only option.
• Users now configure a maximum block size in generators, not individual blocks.
• Maximum datagram size in bytes for unix datagram generator is 8,192.
• Altered default cache construction from 'fixed' to 'streaming'
• Increased maximum DogStatsD context limit from 100k to 1M
• Procfs generator now generates process names as long as 254 characters, up from 253.

Fixed

• The capture manager will no longer panic if recording a capture and checking for a shutdown combined takes longer than one second.
• A shutdown race was partially fixed in the capture manager which could result in truncated (invalid) json capture files.
• Unix datagram generator will not longer 'shear' blocks across datagrams.
• Procfs generator now generates pid/stat files with comm in parens, matching Linux behavior.
