Unified observability signifies the possession of one consistent view over all the parts of a distributed system - applications, infrastructure, and services. With modern systems being spread over several clouds, microservices, and APIs, the only way to have such visibility is through open standards and distributed tracing. Standards such as OpenTelemetry not only make it easier to collect but also to correlate the telemetry data (logs, metrics, and traces) from various components.
"Ampere gave us a leg up to understand how to best instrument the code, and run it in that setup," remarked Antoine Toulmé, who maintains the OpenTelemetry Collector project while serving as a senior engineering manager at Splunk.
