  • pthreads
  • hiredis (install via brew or your favourite package manager)
  • statsd-c-client (fetch using git submodule)
  • RedisModulesSDK ()

Compile

  1. fetch submodules, run the following:
git submodule init
git submodule update
  1. compile RedisModulesSDK:
cd RedisModulesSDK/rmutil
make
  1. go back to main directory, and create a bin directory, run cmake and compile:

make

the module should be in your current directory (bin) named libredis_info_statsd.dylib or libredis_info_statsd.so.

load module

using the loadmodule command, or by configuration file: loadmodule PATH_TO_redis-info-statsd/bin/libredis_info_statsd.dylib

By default the module will send the metrics to localhost:8125 using the namespace "redis" you can override it by passing 3 arguments to loadmodule: loadmodule PATH_TO_redis-info-stats/bin/libredis_info_statsd.dylib 172.16.0.2 8125 redis-23
