Monitor Service IllegalState Exception Critical Failure-created-by-agentic

[shaykeren]

Issue Description

The MonitorService is experiencing critical IllegalStateException failures that are unhandled and occurring frequently. This is causing service instability and needs to be addressed.

Root Cause

1. The monitor() method deliberately throws IllegalStateException without proper handling
2. No circuit breaker or fallback mechanisms are in place
3. Error injection is hardcoded rather than configurable
4. Insufficient instrumentation for monitoring and debugging

Solution

A PR has been created (#55) that implements the following fixes:

1. Makes error injection configurable for testing purposes
2. Implements circuit breaker pattern to prevent cascading failures
3. Adds proper error handling with recovery mechanisms
4. Enhances OpenTelemetry instrumentation

Implementation Details

The changes include:

• Configuration for controlling error injection
• Circuit breaker implementation with failure counting
• Recovery logic with exponential backoff
• Enhanced OpenTelemetry attributes and events

Testing

The solution can be tested by:

1. Running with error injection enabled/disabled
2. Verifying circuit breaker activation
3. Checking recovery behavior
4. Monitoring OpenTelemetry metrics
