## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 22, release rhythm 8, longevity 100
- inputs: {"age_days": 4209, "days_push": 473, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Google's C++14 application-level logging library providing stream-based logging APIs and helper macros. The project is deprecated and will be archived on 2025-06-30, with ng-log and Abseil Logging as recommended successors.

## Use cases
- add structured logging to a C++ application
- log with severity levels like INFO, WARNING, ERROR
- replace printf debugging with stream-style logging macros
- configure log output to files and stderr in C++
- migrate legacy glog-based code to a maintained fork

## When to choose
- maintaining or reading legacy C++ code that already depends on glog
- you need the exact historical glog API for compatibility

## When to avoid
- starting a new C++ project - use ng-log or Abseil Logging instead
- you need bug fixes or ongoing support, since the project is archived

## Facets
- artifact type: library
- maturity: abandoned
- function: logging
- domain: developer-tools, backend
- platform: cpp, cross-platform
- tags: google-logging, deprecated, stream-logging, macros
