@Prashant Shahi thank you for your response. I’m specifically looking into
federated
apis. Is that within the capabilities of signoz?

Which language/framework are you using for graphql sdk? Apollo does support tracing for federated gateways: https://www.apollographql.com/docs/federation/metrics

@Vishal Sharma my company uses fastify and apollo seems to be not an option in the time being

@Kerem Kazan Fastify supports opentelemetry instrumentation. Which library are you using to implement graphql? Mercurius? Even it supports opentelemetry instrumentation: https://mercurius.dev/#/docs/integrations/open-telemetry

@Vishal Sharma we’ve been able to get opentelemetry to work with our graphql backend a while ago (maybe a few months), but we’re not able to get distributed tracing on our federated gateway that aggreagtes the spans in a cohesive way
