Comparisons anchored on OpenTelemetry, the vendor-neutral CNCF telemetry framework, and its Apache-2.0 Collector, covering how telemetry pipelines are deployed.
Whether to run the OpenTelemetry Collector as an agent next to each application or host, as a central gateway that receives all telemetry at one OTLP endpoint, or both in tiers. Covers the pros and cons the OpenTelemetry docs list for each pattern, centralized credentials and policy, and trace-aware load balancing for tail sampling.
Which agent to run on every node: the OpenTelemetry Collector against Fluent Bit, the C-based agent with native OpenTelemetry support, on logs versus traces and metrics, resource footprint, processing features and how they combine in one pipeline.
The upstream OpenTelemetry Collector against Grafana Alloy, Grafana's Apache-2.0 Collector distribution with built-in Prometheus pipelines: component coverage, configuration, release cadence, vendor neutrality and fit with a Grafana stack.
