I Built chanprobe Because My Go Queues Were Invisible
Pavel Sanikovich developed chanprobe to address the limitations of Go channels in production environments. The tool provides insights into channel performance, such as job wait times and potential bottlenecks. By offering a more detailed view of channel activity, chanprobe aims to improve observability and debugging for developers using Go.
- ▪Chanprobe was created to solve the problem of invisible latency in Go channels.
- ▪It allows developers to monitor metrics like job wait times and queue lengths.
- ▪The tool is designed to be simple and explicit, enhancing observability without replacing existing channels.

They are one of those language features that feel simple in the best possible way. You can write something like this: jobs := make(chan Job, 1024) go func() { for job := range jobs { process(job) } }() Enter fullscreen mode Exit fullscreen mode And for a lot of cases, that is enough. Clean, readable, idiomatic.
