Key Points

  • This research aims to compare modern observability tools for performance and scalability in high-traffic environments.
  • Comparative benchmarking of Prometheus, Grafana, Datadog, and OpenTelemetry.
  • Evaluation of metrics such as query latency, resource utilization, and distributed tracing overhead.
  • Workloads tested reached up to 10 million events per second.
  • Prometheus demonstrated superior metrics ingestion throughput compared to its peers.
  • Grafana excelled in query latency, reducing delays significantly under high-load conditions.
  • Datadog showed effective resource utilization, with lower overhead in distributed tracing.

Abstract

This research paper presents a comparative benchmarking study of modern observability tools including Prometheus, Grafana, Datadog, and OpenTelemetry in high-traffic cloud-native environments. The study evaluates performance, scalability, resource utilization, query latency, metrics ingestion throughput, and distributed tracing overhead under workloads reaching up to 10 million events per second. The research aims to help DevOps and Site Reliability Engineering (SRE) teams select efficient observability solutions for large-scale distributed systems based on operational requirements, scalability needs, and cost-performance trade-offs.
