gruf-profiler - Profiler for gruf
Adds a profiler interceptor for gruf 2.0.0 or later.
Then in an initializer or before use, after loading gruf:
require 'gruf/profiler' Gruf.configure do |c| c.interceptors.use(Gruf::Profiler::Interceptor) end
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
