Pure Nim implementation of StatsD-compatible daemon

This work is based upon the bitly go statsd implementaion.

Currently supported:

Type	Status	Notes
timers	WORKING
counters	WORKING
sets	WORKING
gauge	WORKING

Configuring the daemon

Daemon is supporting the ini format config. Filename is statsd.ini

example:

address = 0.0.0.0:8125
graphite = 127.0.0.1:2003
delete-gauges = true
flush-interval = 10
persist-count-keys = 60

supported parameters:

Parameter name	Description	Default value
address	UDP socket address on which daemon will listen incoming packets	0.0.0.0:8125
tcpaddr	TCP socket address on which daemon will listen incoming packets	empty (disabled)
graphite	Address of graphite instance	127.0.0.1:2003
delete-gauges	Will clear gauges after sending to graphite	true
flush-interval	Interval in seconds to send data to graphite	10
prefix	Prefix which will be added to all metrics	empty (disabled)
postfix	Postfix which will be added to all metrics	empty (disabled)
persist-count-keys	Iterations to wait before delete the counter from the metrics if inactive	60
percentiles	Percentile settings for timers as a list of numbers split by comma (e.x. 80,90,95)	empty (disabled)

Building and installation

To build this daemon you either should install nim toolchain see Nim installation or use a supplied docker file.

Manual building

To build daemon you should use

Debug mode

nimble build

Release mode

nimble build -d:release -l:"-flto" -t:"-flto" --opt:size --threads:on
objcopy --strip-all -R .comment -R .comments  statsdaemon

Docker building

Docker building requires the preconfigured statsd.ini file to be in the current directory.

docker build --target release -t statsdaemon .
