gruf-profiler - Profiler for gruf

Adds a profiler interceptor for gruf 2.0.0 or later.

gem 'gruf-profiler'

Then in an initializer or before use, after loading gruf:

require 'gruf/profiler'

Gruf.configure do |c|
  c.interceptors.use(Gruf::Profiler::Interceptor)
end

gruf-profiler includes and requires the rbtrace and memory_profiler gems by default.

rbtrace is automatically loaded for every gruf service. You can view the README for rbtrace for more information, but the general idea is that you can run against a running gruf instance to see tracing information about a gruf server:

rbtrace -p <PID_OF_GRUF> --firehose

Other options for the rbtrace binary are detailed in the rbtrace documentation.

Memory Profiler is a gem that allows you to get a memory usage report of a block of Ruby code. gruf-profiler automatically wraps gruf service requests with this and provides a report to the logger (at a default level of DEBUG).

You can adjust that log level to say, INFO, like so:

Gruf.configure do |c|
  c.interceptors.use(Gruf::Profiler::Interceptor, log_level: :info)
end
