How can a bottleneck causing a violation of the SLA be identified?

To identify the bottleneck causing SLA violation, the following approaches can be used:
-
Application profiling — run a profiler (e.g., VisualVM, YourKit, JProfiler) to measure method execution times and identify "heavy" code sections.
-
Logging and tracing — add time measurements at the start and end of key operations to understand where delays occur.
-
Metrics monitoring — use monitoring systems (Prometheus, Grafana) to track response times, CPU load, memory, and database delays.
-
Dependency analysis — check if external services or databases are causing delays.
-
Load testing — reproduce the load under which SLA is violated and analyze behavior.
Example of simple time measurement in Java:
long start = System.currentTimeMillis();
// method call
long end = System.currentTimeMillis();
System.out.println("Execution time: " + (end - start) + " ms");
Thus, systematic collection and analysis of execution time data help localize bottlenecks and optimize them.
