Monitoring & Observability

Monitoring and observability tools provide visibility into system health, performance, and behavior, enabling proactive incident response and system optimization. The landscape shows clear specialization by function: Prometheus and Grafana dominate metrics collection and visualization with >50% prevalence in Observability & Monitoring positions, representing the modern open-source observability stack. Commercial APM solutions like Datadog, Dynatrace, New Relic, and AppDynamics serve enterprise monitoring needs (>10-25% in observability roles), offering comprehensive application performance insights. Logging infrastructure centers on ELK Stack (ElasticSearch, Logstash, Kibana) with >50% combined prevalence, while Splunk maintains enterprise presence (>25% in observability contexts). These tools appear broadly across backend engineering, DevOps, and platform roles, with observability becoming increasingly critical for microservices and distributed systems. Entry-level accessibility is strongest for Prometheus/Grafana (>55% combined in entry-level observability roles) and ELK Stack components, reflecting open-source tool adoption. The convergence of metrics, logs, and traces under unified observability platforms shapes modern monitoring strategies.

Metrics Collection & Visualization

Open-source and commercial platforms for collecting, storing, and visualizing time-series metrics data. Prometheus and Grafana form the dominant open-source stack for modern monitoring, appearing together across observability, DevOps, and platform engineering. Commercial alternatives like Datadog and Dynatrace offer integrated solutions. Strong entry-level opportunities for Prometheus/Grafana.
