Top 23 Go Logging Projects

  • logrus

    Structured, pluggable logging for Go.

    Project mention: Beautiful graph visualizations of packages for different managers | news.ycombinator.com | 2024-06-27

    The graphics remind me very much of Netwars [1], although the controls of Netwars were a little bit better. However, this feels so good compared to some randomly generated universe, as you know that every star is something meaningful. And you can find actually helpful stuff: I just found logrus [2] a Go library for logging, which sounds cool :-D

  • loki

    Like Prometheus, but for logs.

    Project mention: 26 Top Kubernetes Tools | dev.to | 2024-06-12

    Loki is a log collation tool from the Grafana family of observability solutions. It aggregates, groups, and labels logs from your applications, helping you troubleshoot problems and monitor activity. Although Loki is a general-purpose tool, it's well-suited to Kubernetes and comes with several Kubernetes-specific features. It automatically scrapes and indexes metadata from your Kubernetes workload objects, such as Pod labels, to accompany your Pod logs.

  • zap

    Blazing fast, structured, leveled logging in Go.

    Project mention: Show HN: WAL Implementation in Golang | news.ycombinator.com | 2024-07-08

    1. You're right! Will fix it to handle this as well as the support for relative directories

    2. Yes, Will integrate a logging library instead of fmt (https://github.com/uber-go/zap)

  • gf

  • zerolog

    Zero Allocation JSON Logger

    Project mention: Go 1.21 Released | news.ycombinator.com | 2023-08-08

    Be aware that there is a performance impact compared to using zerolog directly [0] (my uneducated guess is it is likely due to pointer indirection).
