go-libp2p-pubsub-tracer

Tracing daemon and tools for pubsub tracing.

Installation

$ git clone git@github.com:libp2p/go-libp2p-pubsub-tracer.git
$ cd go-libp2p-pubsub-tracer
$ go install ./...

Tools

traced

This is the tracing daemon for receiving and recording traces from remote pubsub peers. Pubsub peers emitting traces should instantiate pubsub using the WithEventTracer option, with an instance of RemoteTracer pointing to your traced instance. Traces are captured as a series of compressed protobuf files, containing the aggregate traces reported from the traced peers.

Usage:

traced [-d <directory>] [-p <port>] [-id <identity>]

  port: port where the traced should listen on; defaults to 4001
  directory: directory where traces should be written; defaults to ./traced.out
  identity: file containing the peer private key; defaults to identity

trace2json

This is a simple tool to convert one or more trace files into json; the json output is dumped to stdout.

Usage:

trace2json <trace-file> ...

tracestat

This is a trace analysis tool, that can analyze one or more trace files.

Usage:

tracestat [-summary] [-cdf] [-json <file>] [-topic <topic>] <trace-file> ...

  -summary: Print an analysis summary to stdout; defaults to true
  -cdf: Print a CDF of message propagation delays to stdout; defaults to false
  -json <file>: Output the result of the analysis to a json file for further processing by other tools
  -topic <topic>: Analyze messages only for a specific topic
