OpenTelemetry Backend

Giriş

Açıklaması şöyle

Even though OpenTelemetry does not provides their own backend, by using it, we are not tied to any tool or vendor, since it is vendor agnostic. Not only can we use any programming language we want, but we can also pick and choose the storage backend and also easily switch to another backend/vendor, by just configure another exporter.

Honeycomb, Lightstep, New Relic, Tempo (Grafana Cloud) gibi bir sürü şey olabilir

Jaeger ve Zipkin

Açıklaması şöyle

Jaeger and Zipkin predate OpenTelemetry, so each has its trace transport format. They do provide integration with the OpenTelemetry format, though.

Jaeger

Açıklaması şöyle
