Minuswell

minus well

Minuswell is a log file shipper for Logstash, written in Go. It supports a number of outputs (and can multiplex them).

Building

$ go get -d -v ./... && go build -v ./...

The go build command creates the minuswell binary for you to install/run.

Notes

• The fsnotify library is currently slightly broken with Linux, so you must use commit d66819e17205a446430d34a9ba41625cec35be19.
• If you get errors with gozmq, check these instructions.

Usage

Usage:
  minuswell [OPTIONS]

Help Options:
  -h, --help              Show this help message

Application Options:
  -c FILE                 Path to config file
  -d, --config-dir DIR    Parse config files in dir
  -o OUTPUT               Which output to use (can specify multiple)

You must specify both config and output. To send to multiple outputs, simply add more -o options to the args.

If you'd like to have minuswell parse multiple config files, it can do that too. Just use --config-dir=path/to/dir.

It uses the shoenice library to provide statistics about the app and send them to Graphite.

Supported outputs

• pipe (stdout) no configuration needed
• tcp - requires specifying address and port
• zmq - set addresses which is an array of ZeroMQ addresses
