Historique du projet

The official README describes alp simply as Access Log Profiler and documents binary releases, Homebrew installation, asdf installation, and command-based usage. The repository's v0.4.0-to-v1.0.0 migration document records a major reshaping from an LTSV-focused profiler into a multi-format tool with subcommands.

Version 1.0.0 added format-specific subcommands such as `ltsv`, `json`, and `regexp`, later joined in the README by `pcap`, `diff`, and `count`. The v1 transition also consolidated sorting and output options, added filters, added selectable output columns, and introduced position-file support so repeated benchmark runs do not require truncating logs.

Historique d'adoption

alp is a focused operations tool rather than a broad observability platform. Its adoption comes from developers and performance testers who want a quick CLI profile of HTTP access logs, especially during load testing or application tuning.

Official installation paths include GitHub release binaries, Homebrew on macOS, and asdf through `asdf-alp`. That makes it easy to pin a profiler version in local benchmark environments without introducing a full logging stack.

Modes d'utilisation

Common usage is to feed alp an access log in LTSV, JSON, or regexp-parsed format and sort/group the results by count, latency statistics, status, URI, method, percentiles, or matching groups. It can output table, markdown, TSV, CSV, and HTML formats.

The README also documents `pcap` profiling for captured HTTP requests, `diff` for comparing two profile results, and `count` for counting log entries. Many flags are label/key/subexpression overrides, which lets alp adapt to site-specific log formats without a separate parser.

Pourquoi les passionnés de paquets s'y intéressent

alp is the sort of small Go CLI that package managers are good at: one binary, clear terminal behavior, and direct value in incident or benchmark loops. It sits between ad hoc `awk` pipelines and heavier log-analysis systems.

The v0.4-to-v1 migration is useful package history because it changed the command surface. Anyone packaging shell completions, examples, or old benchmark scripts needs to know that the older one-command LTSV shape became a subcommand-based multi-format CLI.
