This is a custom build of the official OpenTelemetry Collector a vendor-agnostic service that allows to receive, process and export telemetry data.
You can simply build the collector by running the following command from the root of the repository:
docker compose -f docker-compose.yml build otelcollector --no-cache(Optional) Please read the Building a custom collector to learn how to build a custom collector. Ensure you have the latest version of the OpenTelemetry Collector Builder installed.
Change the TTL of the otel_metrics_* table to 3 days. In that way, raw metrics will be deleted after 3 days but the materialized view will still be available for 30 days in a compressed format.
Run this for each metrics table:
ALTER TABLE otel_metrics_histogram MODIFY TTL toDateTime(TimeUnix) + toIntervalDay(7);
OPTIMIZE TABLE otel_metrics_histogram FINAL;
