Equivalent of /rpcz at Google

[mrjn (Manish R Jain)]

Hey folks,

Has anyone built the Go equivalent of /rpcz that Google’s servers have? The idea is to be able to locate the rpcs which are either currently running, or get a sample of rpcs which took over X%-ile latency.

Just to avoid confusion, there’s an equivalent of Dapper for Go, but that’s not what I’m talking about. The /rpcz handler runs only for that one server, and only shows rpcs for that one server; and not across servers.

If there’s none, my team is interested in building one. So, would love to bounce ideas, and best practices regarding how to build this.

Cheers,
Manish

Yes, it’s built into gRPC.

Thanks @dfc! This is exactly what I needed. In particular, the net/trace package.
