Configuration for the ocurl backend

type t = private {

debug : bool;
url_traces : string;
(*
Url to send traces
*)
url_metrics : string;
(*
Url to send metrics
*)
url_logs : string;
(*
Url to send logs
*)
headers : (string * string) list;
(*
API headers sent to the endpoint. Default is none or "OTEL_EXPORTER_OTLP_HEADERS" if set.
*)
batch_timeout_ms : int;
(*
Number of milliseconds after which we will emit a batch, even incomplete. Note that the batch might take longer than that, because this is only checked when a new event occurs or when a tick is emitted. Default 2_000.
*)
bg_threads : int;
(*
Are there background threads, and how many? Default 4. This will be adjusted to be at least 1 and at most 32.
*)
ticker_thread : bool;
(*
If true, start a thread that regularly checks if signals should be sent to the collector. Default true
*)
ticker_interval_ms : int;
(*
Interval for ticker thread, in milliseconds. This is only useful if ticker_thread is true. This will be clamped between 2 ms and some longer interval (maximum 60s currently). Default 500.
- since 0.7
*)
self_trace : bool;
(*
If true, the OTEL library will also emit its own spans. Default false.
- since 0.7

To build one, use make below. This might be extended with more fields in the future.

Make a configuration.

parameter url
base url used to construct per-signal urls. Per-signal url options take precedence over this base url. Default is "http://localhost:4318", or "OTEL_EXPORTER_OTLP_ENDPOINT" if set.
Example of constructed per-signal urls with the base url http://localhost:4318
- Traces: http://localhost:4318/v1/traces
- Metrics: http://localhost:4318/v1/metrics
- Logs: http://localhost:4318/v1/logs
Use per-signal url options if different urls are needed for each signal type.

parameter url_traces
url to send traces, or "OTEL_EXPORTER_OTLP_TRACES_ENDPOINT" if set. The url is used as-is without any modification.

parameter url_metrics
url to send metrics, or "OTEL_EXPORTER_OTLP_METRICS_ENDPOINT" if set. The url is used as-is without any modification.

parameter url_logs
url to send logs, or "OTEL_EXPORTER_OTLP_LOGS_ENDPOINT" if set. The url is used as-is without any modification.
