Angel98518 98b6a0e6d1 feat: Add OceanBase Performance Monitoring and Health Check Integration (#12886)
## Description

This PR implements comprehensive OceanBase performance monitoring and
health check functionality as requested in issue #12772. The
implementation follows the existing ES/Infinity health check patterns
and provides detailed metrics for operations teams.

## Problem

Currently, RAGFlow lacks detailed health monitoring for OceanBase when
used as the document engine. Operations teams need visibility into:
- Connection status and latency
- Storage space usage
- Query throughput (QPS)
- Slow query statistics
- Connection pool utilization

## Solution

### 1. Enhanced OBConnection Class (`rag/utils/ob_conn.py`)

Added comprehensive performance monitoring methods:
- `get_performance_metrics()` - Main method returning all performance
metrics
- `_get_storage_info()` - Retrieves database storage usage
- `_get_connection_pool_stats()` - Gets connection pool statistics
- `_get_slow_query_count()` - Counts queries exceeding threshold
- `_estimate_qps()` - Estimates queries per second
- Enhanced `health()` method with connection status

### 2. Health Check Utilities (`api/utils/health_utils.py`)

Added two new functions following ES/Infinity patterns:
- `get_oceanbase_status()` - Returns OceanBase status with health and
performance metrics
- `check_oceanbase_health()` - Comprehensive health check with detailed
metrics

### 3. API Endpoint (`api/apps/system_app.py`)

Added new endpoint:
- `GET /v1/system/oceanbase/status` - Returns OceanBase health status
and performance metrics

### 4. Comprehensive Unit Tests
(`test/unit_test/utils/test_oceanbase_health.py`)

Added 340+ lines of unit tests covering:
- Health check success/failure scenarios
- Performance metrics retrieval
- Error handling and edge cases
- Connection pool statistics
- Storage information retrieval
- QPS estimation
- Slow query detection

## Metrics Provided

- **Connection Status**: connected/disconnected
- **Latency**: Query latency in milliseconds
- **Storage**: Used and total storage space
- **QPS**: Estimated queries per second
- **Slow Queries**: Count of queries exceeding threshold
- **Connection Pool**: Active connections, max connections, pool size

## Testing

- All unit tests pass
- Error handling tested for connection failures
- Edge cases covered (missing tables, connection errors)
- Follows existing code patterns and conventions

## Code Statistics

- **Total Lines Changed**: 665+ lines
- **New Code**: ~600 lines
- **Test Coverage**: 340+ lines of comprehensive tests
- **Files Modified**: 3
- **Files Created**: 1 (test file)

## Acceptance Criteria Met

 `/system/oceanbase/status` API returns OceanBase health status
 Monitoring metrics accurately reflect OceanBase running status
 Clear error messages when health checks fail
 Response time optimized (metrics cached where possible)
 Follows existing ES/Infinity health check patterns
 Comprehensive test coverage
