almaz

almaz

Carbon-like metric collection daemon which stores all data in memory and does not use disk.

Install

This repository contains a Go workspace. Clone it...

git clone https://github.com/Babazka/almaz.git

Compile and run:

make
bin/almaz

Almaz will listen on port 7701 for metrics, and on port 7702 for data queries. Ports can be changed with command-line options.

Submitting metrics to almaz

Almaz receives metrics using the same protocol Carbon uses. Send metrics over plain TCP, one line per metric:

stats_counts.adv.shows.429.2005.4186 16 1377447313
statsd.numStats 5001 1377447313
stats.statsd.graphiteStats.calculationtime 18 1377447313
stats.statsd.processing_time 2 1377447313
stats.statsd.graphiteStats.last_exception 1377435453 1377447313
stats.statsd.graphiteStats.last_flush 1377446503 1377447313
stats.statsd.graphiteStats.flush_time 21 1377447313
stats.statsd.graphiteStats.flush_length 471582 1377447313

Lines are separated by \n. Each line contains three fields -- metric name (string without spaces), metric value (float), and Unix timestamp (integer), separated by one space. You can submit an arbitrary number of metrics in a single connection.
