statsd-zig

Basic DogStatsD UDP/UDS server supporting gauges and counters and sending these metrics to Datadog.

Getting started

libcurl must be available on the system
Build the binary with zig build (build with Zig 0.9.1)
Set the environment variables APIKEY and HOSTNAME to configure the daemon

With UDP

Launch the daemon and start sending it counters and gauges on port udp/8125

With UDS

Set the environment variable UDS to a filepath of the unix socket you want to use
Sends counters and gauges on this unix socket with a DogStatsD client

Memory usage

I've developed a custom memory allocator measuring how much memory is allocated while processing the metrics (see measure_allocator.zig).

Using this allocator, the memory is allocated, used, and forgotten for a while. When the total amount of allocated memory reaches a certain size, it is completely freed.

This provides two benefits:

close to no time spent freeing memory
you can easily configure the maximum amount of memory the server can use (set MAX_MEM_MB, default value 256)
