v3.1.1

This is prmon release v3.1.1, Ross 128

Major item is the support for fast memory monitoring, which itself probably deserves a new minor release instead of a patch but hindsight is always 20/20. In addition, the plotting script is updated to respect the new naming scheme of the built-in matplotlib styles.

What's Changed

• Add support for fast memory monitoring using smaps_rollup by @amete in #234
• Update the default plotting style by @amete in #245

v3.0.2

This is prmon release v3.0.2, Epsilon Eridani

This is a minor prmon release that adds the funtionality to use spdlog and nlohmann_json as either externals or as submodules.

Fixed some minor bug fixes for the builds and utility targets.

Thanks to Chuck Atkins for the external/internal CMake changes.

Full ChangeLog: v3.0.1...v3.0.2

v3.0.1

This is the Ross 248 release, which is a minor update of prmon.

Highlight Changes

• Fixes the clang compilation problem reported in #210
• Adds a new CI build using the clang compiler
• Adds a new GitHub action that builds the source code tarball to fix the issue reported by @nikoladze in #209

What's Changed (Detailed)

• Added source release action by @graeme-a-stewart in #214
• Clang CI option by @graeme-a-stewart in #213
• Clang fixes by @graeme-a-stewart in #212

Full ChangeLog: v3.0.0...v3.0.1

v3.0.0

This is the Ross 154 release, which is a major upgrade of prmon.

Highlight Changes

• A logging infrastructure has been introduced, using the spdlog backend. Logging can be adjusted globally or on a per-monitor basis
  using the --level argument (#190)
• Monitored values that are known to be monotonic increasing are now protected from race conditions that might cause them to drop in
  value (#196) (this relies in a major reworking of how values are stored internally to prmon)
• Unit tests are introduced to check that monitors behave correctly when faced with unexpected readings from the system (e.g., monotonic value decreases) (#197), this relies on the GoogleTest framework
• Tests are also introduced to ensure that all expected monitored values are present in the text and JSON output files (#205)
• Python2 support is dropped in all supporting scripts
• A script to compress prmon's output files is now properly shipped in the release (prmon_compress_output.py) (#207)

What's Changed (Detailed)

• Added logging functionality (spdlog) by @quantum-shift in #190
• Fix: cpumon doesn't reset values each iteration by @quantum-shift in #194
• Added command line switches to control logging level of monitors by @quantum-shift in #193
• Integrate GoogleTest framework for unit tests by @quantum-shift in #197
• Added new montored value class by @graeme-a-stewart in #196
• Precooked tests for monitors by @quantum-shift in #195
• Relocated benchmark.cpp to package/benchmarks by @quantum-shift in #198
• Fixed netmon initialisation bug #199 by @quantum-shift in #200
• Drop python2 support and remove u18 from the supported platforms by @amete in #203
• Update Python scripts to Python3 by @graeme-a-stewart in #204
• Fix wallclock units by @graeme-a-stewart in #206
• Add tests against missing fields in prmon txt and json outputs by @quantum-shift in #205
• Start installing prmon_compress_output.py by default by @amete in #207

New Contributors

• @quantum-shift made their first contribution in #190

Full Changelog: v2.2.1...v3.0.0

Addendum (25/01/2022):

Two more assets are added:

1. v3.0.0.tar.gz containing the source code including spdlog,
2. prmon_3.0.0_aarch64-static-gnu85-opt.tar.gz containing the static build on aarch64.

v2.2.1

This is the Luyten 726-8 A release

This release includes a minor update to allow compiling under gcc11, see #192 for more details.

v2.2.0

This is the Luyten 726-8 release

This release includes the following improvements:

• Ability to disable components (#178 and #183)
• Patch for the network statistics rollover (#181)
• Bugfix for argument parsing (#179)
• Adding program version information to the JSON output (#176)
• Adding a python script that lossy compresses the text output (#172 thanks to @rmaganza 👍 )

v2.1.1

This is the Sirus-alpha release

Implement a bug fix for cases where the monitored process tree heirarchy loses I/O stats right at the end of the job. (Discussed in #173.)

v2.1.0

This is the Sirius release

The number of decimal places output for average values in the JSON summary is
now limited to a sensible accuracy (#161).

When prmon invokes the monitored process the exit code from the process is
propagated as the exit code of prmon (#163); thanks to Chris Burr for this
enhancement.

All Python scripts were reformatted with black and cleaned with flake8 (#168);
this is now the coding standard for prmon Python.

A warning message is printed when the monitored process wallclock time is very
short (#166).

nvidia-smi parsing was fixed to cope with the situation where the enc/dec
values are hyphens instead of a 0 (#167).

The CLANG_FORMAT binary setting is now properly respected (#171).

v2.0.2

This is the Lalande 21185 release

Includes a bug-fix in the axis unit consistency check in the plotting script.
