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 0.11.0)
• 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)
