massemanet/eper

This system is an Erlang-based monitoring and diagnostics toolkit designed for observing and analyzing runtime behavior. It provides command-line utilities for tracking network, memory, and process metrics, alongside modules for parsing log files and replaying trace data. The project also includes CI configuration and release automation tools to support its development lifecycle.

A new shell script at bin/release.sh has been added to automate the process of incrementing the project's version number (major, minor, or patch) and generating a corresponding Git tag and changelog. This tool simplifies the release workflow by handling version updates in the source file, committing the change, and creating an annotated tag.

bin · high confidence

Introduces several new modules to the src directory: atop.erl for visualizing allocator information, bread.erl and bread\_server.erl for parsing various file formats (XML, terms, lines, TRC) with support for compressed files, dogConsumer.erl for handling watchdog data, dtop.erl and dtopConsumer.erl for a top-like client for prf, dtop\_replay.erl for replaying TRC files, eper.app.src and eper.erl for the main application entry point and command-line interface, gen\_serv.erl and gen\_serv.hrl as a generic server behavior wrapper, getoptw.erl for command-line argument parsing, log.hrl for logging macros, logReader.erl for reading compressed log files, loggerConsumer.erl for logging prf data to files, mtop.erl for Mnesia monitoring, ntop.erl and ntopConsumer.erl for network top monitoring, prf.erl as the main PRF interface, prfConsumer.erl as an example consumer, and prfDist.erl for collecting distribution port statistics.

src · high confidence

Three new executable shell scripts—dtop, ntop, and redbug—have been added to the priv/bin directory. These scripts provide command-line interfaces for Erlang-based tools, supporting options for node names, cookies, network tick times, and OTP versions. The redbug script specifically handles long node names and trace patterns, while dtop and ntop manage their respective Erlang processes with similar configuration options.

priv · high confidence

The repository now includes a \.gitignore\ file to exclude build artifacts and editor backups, and a \.travis.yml\ file to configure continuous integration testing across multiple Erlang/OTP versions (R16B03-1 through 21.0).
