Spring Data Repository Performance Dashboard

This dashboard provides deep visibility into the performance of Spring Data repository methods in a Spring Boot application. It uses Prometheus metrics exposed by Micrometer to monitor:

• Latency (average duration in milliseconds, max observed spikes)
• Throughput (calls per second)
• Error rate (% of failed invocations)
• Exceptions breakdown (errors/sec and total occurrences)
• Slow & Frequent analysis (methods that are both slow and high-volume)

The dashboard includes:

• Top 10 slowest methods and Top 10 most frequent methods
• Time-series panels for latency, error rate, and max duration spikes
• Tables with thresholds and row coloring for quick identification of problematic queries
• Collapsible rows for easy navigation: Overview, Top Lists, Latency & Spikes, Reliability, Prioritization
• Global throughput trend to correlate load with latency issues

Prerequisites:

• Spring Boot application with Micrometer metrics enabled
• Prometheus as the data source
• Metrics: spring_data_repository_invocations_seconds_* (summary and max)

Use cases:

• Identify slow queries and optimize database performance
• Detect error spikes and troubleshoot exceptions
• Prioritize fixes for methods that impact user experience most
