OpenTelemetry is gaining traction as an open-source project for monitoring applications, prompting organizations to carefully choose vendors that support this technology. Key considerations when selecting a vendor include assessing their commitment to OpenTelemetry and open standards, understanding how their observability solutions manage OpenTelemetry data, and evaluating the features available for managing and optimizing costs. Vendors like Grafana Labs actively contribute to OpenTelemetry and focus on interoperability with other tools such as Prometheus, offering native support for OpenTelemetry protocol data across metrics, logs, and traces. They also provide tools for cost management and predictability, ensuring that users can efficiently collect and utilize the most pertinent data.
