Can you give examples of systems you have used for tracking query or operation execution?

To track the execution of requests or operations, I used the following systems:

• ELK Stack (Elasticsearch, Logstash, Kibana) — for collecting, storing, and visualizing logs and metrics.
• Prometheus + Grafana — for monitoring and alerting, tracking execution metrics.
• Jaeger — for distributed tracing of requests in microservices.
• Sentry — for real-time error and exception tracking.
• New Relic, Datadog — commercial solutions for performance monitoring and tracing.

For example, with Jaeger, you can visualize the request path across different services and identify bottlenecks in performance.
