# Migration to uv
|
||||
|
||||
This document describes the migration from traditional Python package management (pip + requirements.txt) to [uv](https://docs.astral.sh/uv/), a fast Python package installer and resolver.
|
||||
|
||||
## What Changed
|
||||
|
||||
### Files Added
|
||||
- `pyproject.toml` - Modern Python project configuration combining dependencies and metadata
|
||||
- `.python-version` - Specifies Python version for uv
|
||||
- `scripts/setup_uv.sh` - Unix setup script for uv environment
|
||||
- `scripts/setup_uv.bat` - Windows setup script for uv environment
|
||||
- This migration guide
|
||||
|
||||
### Files Modified
|
||||
- `Makefile` - Updated all commands to use `uv run` instead of direct Python execution
|
||||
|
||||
### Files That Can Be Removed (Optional)
|
||||
- `requirements.txt` - Dependencies now in pyproject.toml
|
||||
- `requirements-dev.txt` - Dev dependencies now in pyproject.toml
|
||||
- `setup.py` - Configuration now in pyproject.toml
|
||||
|
||||
## Installation
|
||||
|
||||
### Install uv
|
||||
|
||||
**Unix/macOS:**
|
||||
```bash
|
||||
curl -LsSf https://astral.sh/uv/install.sh | sh
|
||||
```
|
||||
|
||||
**Windows (PowerShell):**
|
||||
```powershell
|
||||
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
|
||||
```
|
||||
|
||||
### Setup Project
|
||||
|
||||
**Unix/macOS:**
|
||||
```bash
|
||||
# Run the setup script
|
||||
chmod +x scripts/setup_uv.sh
|
||||
./scripts/setup_uv.sh
|
||||
|
||||
# Or manually:
|
||||
uv sync
|
||||
uv run pre-commit install
|
||||
```
|
||||
|
||||
**Windows:**
|
||||
```batch
|
||||
REM Run the setup script
|
||||
scripts\setup_uv.bat
|
||||
|
||||
REM Or manually:
|
||||
uv sync
|
||||
uv run pre-commit install
|
||||
```
|
||||
|
||||
## New Workflow
|
||||
|
||||
### Common Commands
|
||||
|
||||
| Old Command | New Command | Description |
|
||||
|-------------|-------------|-------------|
|
||||
| `pip install -r requirements.txt` | `uv sync --no-dev` | Install production dependencies |
|
||||
| `pip install -r requirements-dev.txt` | `uv sync` | Install all dependencies (including dev) |
|
||||
| `python run.py` | `uv run python run.py` | Run the application |
|
||||
| `pytest` | `uv run pytest` | Run tests |
|
||||
| `black src/` | `uv run black src/` | Format code |
|
||||
|
||||
### Using the Makefile
|
||||
|
||||
The Makefile has been updated to use uv, so all existing commands work the same:
|
||||
|
||||
```bash
|
||||
make install-dev # Install dev dependencies with uv
|
||||
make test # Run tests with uv
|
||||
make run-api # Start API server with uv
|
||||
make lint # Lint code with uv
|
||||
make format # Format code with uv
|
||||
```
|
||||
|
||||
### Adding Dependencies
|
||||
|
||||
**Production dependency:**
|
||||
```bash
|
||||
uv add requests
|
||||
```
|
||||
|
||||
**Development dependency:**
|
||||
```bash
|
||||
uv add --dev pytest
|
||||
```
|
||||
|
||||
**Specific version:**
|
||||
```bash
|
||||
uv add "fastapi==0.104.1"
|
||||
```
|
||||
|
||||
### Managing Python Versions
|
||||
|
||||
uv can automatically manage Python versions:
|
||||
|
||||
```bash
|
||||
# Install and use Python 3.11
|
||||
uv python install 3.11
|
||||
uv sync
|
||||
|
||||
# Use specific Python version
|
||||
uv sync --python 3.11
|
||||
```
|
||||
|
||||
## Benefits of uv
|
||||
|
||||
1. **Speed** - 10-100x faster than pip
|
||||
2. **Reliability** - Better dependency resolution
|
||||
3. **Simplicity** - Single tool for packages and Python versions
|
||||
4. **Reproducibility** - Lock file ensures consistent environments
|
||||
5. **Modern** - Built-in support for pyproject.toml
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Command not found
|
||||
Make sure uv is in your PATH after installation. Restart your terminal or run:
|
||||
```bash
|
||||
source ~/.bashrc # or ~/.zshrc
|
||||
```
|
||||
|
||||
### Lock file conflicts
|
||||
If you encounter lock file issues:
|
||||
```bash
|
||||
rm uv.lock
|
||||
uv sync
|
||||
```
|
||||
|
||||
### Python version issues
|
||||
Ensure the Python version in `.python-version` is available:
|
||||
```bash
|
||||
uv python list
|
||||
uv python install 3.11 # if needed
|
||||
```
|
||||
|
||||
## Rollback (if needed)
|
||||
|
||||
If you need to rollback to the old system:
|
||||
|
||||
1. Use the original requirements files:
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
pip install -r requirements-dev.txt
|
||||
```
|
||||
|
||||
2. Revert the Makefile changes to use `python` instead of `uv run python`
|
||||
|
||||
3. Remove uv-specific files:
|
||||
```bash
|
||||
rm pyproject.toml .python-version uv.lock
|
||||
rm -rf .venv # if created by uv
|
||||
```
|
||||

# PostgreSQL Setup for Northern Thailand Ping River Monitor
|
||||
|
||||
This guide helps you configure PostgreSQL as the database backend for the water monitoring system.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- PostgreSQL server running on a remote machine (already available)
|
||||
- Network connectivity to the PostgreSQL server
|
||||
- Database credentials (username, password, host, port)
|
||||
|
||||
## Quick Setup
|
||||
|
||||
### 1. Configure Environment
|
||||
|
||||
Copy the example environment file and configure it:
|
||||
|
||||
```bash
|
||||
cp .env.example .env
|
||||
```
|
||||
|
||||
Edit `.env` and update the PostgreSQL configuration:
|
||||
|
||||
```bash
|
||||
# Database Configuration
|
||||
DB_TYPE=postgresql
|
||||
|
||||
# PostgreSQL Configuration (Remote Server)
|
||||
POSTGRES_CONNECTION_STRING=postgresql://username:password@your-postgres-host:5432/water_monitoring
|
||||
```
|
||||
|
||||
### 2. Run Setup Script
|
||||
|
||||
Use the interactive setup script:
|
||||
|
||||
```bash
|
||||
# Using uv
|
||||
uv run python scripts/setup_postgres.py
|
||||
|
||||
# Or using make
|
||||
make setup-postgres
|
||||
```
|
||||
|
||||
The script will:
|
||||
- Test your database connection
|
||||
- Create the database if it doesn't exist
|
||||
- Initialize the required tables and indexes
|
||||
- Set up sample monitoring stations
|
||||
|
||||
### 3. Test Connection
|
||||
|
||||
Test your PostgreSQL connection:
|
||||
|
||||
```bash
|
||||
make test-postgres
|
||||
```
|
||||
|
||||
### 4. Run the Application
|
||||
|
||||
Start collecting data:
|
||||
|
||||
```bash
|
||||
# Run a test cycle
|
||||
make run-test
|
||||
|
||||
# Start the web API
|
||||
make run-api
|
||||
```
|
||||
|
||||
## Manual Configuration
|
||||
|
||||
If you prefer manual setup, here's what you need:
|
||||
|
||||
### Connection String Format
|
||||
|
||||
```
|
||||
postgresql://username:password@host:port/database
|
||||
```
|
||||
|
||||
**Examples:**
|
||||
- Basic: `postgresql://postgres:mypassword@192.168.1.100:5432/water_monitoring`
|
||||
- With SSL: `postgresql://user:pass@host:5432/db?sslmode=require`
|
||||
- With connection pooling: `postgresql://user:pass@host:5432/db?pool_size=20&max_overflow=0`
|
||||
|
||||
### Environment Variables
|
||||
|
||||
| Variable | Description | Example |
|
||||
|----------|-------------|---------|
|
||||
| `DB_TYPE` | Database type | `postgresql` |
|
||||
| `POSTGRES_CONNECTION_STRING` | Full connection string | See above |
|
||||
|
||||
### Database Schema
|
||||
|
||||
The application uses these main tables:
|
||||
|
||||
1. **stations** - Monitoring station information
|
||||
2. **water_measurements** - Time series water level data
|
||||
3. **alert_thresholds** - Warning/danger level definitions
|
||||
4. **data_quality_log** - Data collection issue tracking
|
||||
|
||||
See `sql/init_postgres.sql` for the complete schema.
|
||||
|
||||
## Connection Options
|
||||
|
||||
### SSL Connection
|
||||
|
||||
For secure connections, add SSL parameters:
|
||||
|
||||
```bash
|
||||
POSTGRES_CONNECTION_STRING=postgresql://user:pass@host:5432/db?sslmode=require
|
||||
```
|
||||
|
||||
SSL modes:
|
||||
- `disable` - No SSL
|
||||
- `require` - Require SSL
|
||||
- `prefer` - Use SSL if available
|
||||
- `verify-ca` - Verify certificate authority
|
||||
- `verify-full` - Full certificate verification
|
||||
|
||||
### Connection Pooling
|
||||
|
||||
For high-performance applications, configure connection pooling:
|
||||
|
||||
```bash
|
||||
POSTGRES_CONNECTION_STRING=postgresql://user:pass@host:5432/db?pool_size=20&max_overflow=0
|
||||
```
|
||||
|
||||
Parameters:
|
||||
- `pool_size` - Number of connections to maintain
|
||||
- `max_overflow` - Additional connections allowed
|
||||
- `pool_timeout` - Seconds to wait for connection
|
||||
- `pool_recycle` - Seconds before connection refresh
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**1. Connection Refused**
|
||||
```
|
||||
psycopg2.OperationalError: could not connect to server
|
||||
```
|
||||
- Check if PostgreSQL server is running
|
||||
- Verify host/port in connection string
|
||||
- Check firewall settings
|
||||
|
||||
**2. Authentication Failed**
|
||||
```
|
||||
psycopg2.OperationalError: FATAL: password authentication failed
|
||||
```
|
||||
- Verify username/password in connection string
|
||||
- Check PostgreSQL pg_hba.conf configuration
|
||||
- Ensure user has database access permissions
|
||||
|
||||
**3. Database Does Not Exist**
|
||||
```
|
||||
psycopg2.OperationalError: FATAL: database "water_monitoring" does not exist
|
||||
```
|
||||
- Run the setup script to create the database
|
||||
- Or manually create: `CREATE DATABASE water_monitoring;`
|
||||
|
||||
**4. Permission Denied**
|
||||
```
|
||||
psycopg2.ProgrammingError: permission denied for table
|
||||
```
|
||||
- Ensure user has appropriate permissions
|
||||
- Grant access: `GRANT ALL PRIVILEGES ON DATABASE water_monitoring TO username;`
|
||||
|
||||
### Network Configuration
|
||||
|
||||
For remote PostgreSQL servers, ensure:
|
||||
|
||||
1. **PostgreSQL allows remote connections** (`postgresql.conf`):
|
||||
```
|
||||
listen_addresses = '*'
|
||||
port = 5432
|
||||
```
|
||||
|
||||
2. **Client authentication is configured** (`pg_hba.conf`):
|
||||
```
|
||||
# Allow connections from your application server
|
||||
host water_monitoring username your.app.ip/32 md5
|
||||
```
|
||||
|
||||
3. **Firewall allows PostgreSQL port**:
|
||||
```bash
|
||||
# On PostgreSQL server
|
||||
sudo ufw allow 5432/tcp
|
||||
```
|
||||
|
||||
### Performance Tuning
|
||||
|
||||
For optimal performance with time series data:
|
||||
|
||||
1. **Increase work_mem** for sorting operations
|
||||
2. **Tune shared_buffers** for caching
|
||||
3. **Configure maintenance_work_mem** for indexing
|
||||
4. **Set up regular VACUUM and ANALYZE** for statistics
|
||||
|
||||
Example PostgreSQL configuration additions:
|
||||
```
|
||||
# postgresql.conf
|
||||
shared_buffers = 256MB
|
||||
work_mem = 16MB
|
||||
maintenance_work_mem = 256MB
|
||||
effective_cache_size = 1GB
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Check Application Status
|
||||
|
||||
```bash
|
||||
# View current configuration
|
||||
uv run python -c "from src.config import Config; Config.print_settings()"
|
||||
|
||||
# Test database connection
|
||||
make test-postgres
|
||||
|
||||
# Check latest data
|
||||
psql "postgresql://user:pass@host:5432/water_monitoring" -c "SELECT COUNT(*) FROM water_measurements;"
|
||||
```
|
||||
|
||||
### PostgreSQL Monitoring
|
||||
|
||||
Connect directly to check database status:
|
||||
|
||||
```bash
|
||||
# Connect to database
|
||||
psql "postgresql://username:password@host:5432/water_monitoring"
|
||||
|
||||
# Check table sizes
|
||||
\dt+
|
||||
|
||||
# View latest measurements
|
||||
SELECT * FROM latest_measurements LIMIT 10;
|
||||
|
||||
# Check data quality
|
||||
SELECT issue_type, COUNT(*) FROM data_quality_log
|
||||
WHERE created_at > NOW() - INTERVAL '24 hours'
|
||||
GROUP BY issue_type;
|
||||
```
|
||||
|
||||
## Backup and Maintenance
|
||||
|
||||
### Backup Database
|
||||
|
||||
```bash
|
||||
# Full backup
|
||||
pg_dump "postgresql://user:pass@host:5432/water_monitoring" > backup.sql
|
||||
|
||||
# Data only
|
||||
pg_dump --data-only "postgresql://user:pass@host:5432/water_monitoring" > data_backup.sql
|
||||
```
|
||||
|
||||
### Restore Database
|
||||
|
||||
```bash
|
||||
# Restore full backup
|
||||
psql "postgresql://user:pass@host:5432/water_monitoring" < backup.sql
|
||||
|
||||
# Restore data only
|
||||
psql "postgresql://user:pass@host:5432/water_monitoring" < data_backup.sql
|
||||
```
|
||||
|
||||
### Regular Maintenance
|
||||
|
||||
Set up regular maintenance tasks:
|
||||
|
||||
```sql
|
||||
-- Update table statistics (run weekly)
|
||||
ANALYZE;
|
||||
|
||||
-- Reclaim disk space (run monthly)
|
||||
VACUUM;
|
||||
|
||||
-- Reindex tables (run quarterly)
|
||||
REINDEX DATABASE water_monitoring;
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Set up monitoring and alerting
|
||||
2. Configure data retention policies
|
||||
3. Set up automated backups
|
||||
4. Implement connection pooling if needed
|
||||
5. Configure SSL for production use
|
||||
|
||||
For more advanced configuration, see the [PostgreSQL documentation](https://www.postgresql.org/docs/).

# SQLite to PostgreSQL Migration Guide
|
||||
|
||||
This guide helps you migrate your existing SQLite water monitoring data to PostgreSQL.
|
||||
|
||||
## Quick Migration
|
||||
|
||||
### 1. Analyze Your SQLite Database (Optional)
|
||||
|
||||
First, check what's in your SQLite database:
|
||||
|
||||
```bash
|
||||
# Analyze without migrating
|
||||
make analyze-sqlite
|
||||
|
||||
# Or specify a specific SQLite file
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py --dry-run /path/to/your/database.db
|
||||
```
|
||||
|
||||
### 2. Run the Migration
|
||||
|
||||
```bash
|
||||
# Auto-detect SQLite file and migrate
|
||||
make migrate-sqlite
|
||||
|
||||
# Or specify a specific SQLite file
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py /path/to/your/database.db
|
||||
```
|
||||
|
||||
The migration tool will:
|
||||
- ✅ Connect to both databases
|
||||
- ✅ Analyze your SQLite schema automatically
|
||||
- ✅ Migrate station information
|
||||
- ✅ Migrate all measurement data in batches
|
||||
- ✅ Handle different SQLite table structures
|
||||
- ✅ Verify the migration results
|
||||
- ✅ Generate a detailed log file
|
||||
|
||||
## What Gets Migrated
|
||||
|
||||
### Station Data
|
||||
- Station IDs and codes
|
||||
- Thai and English names
|
||||
- Coordinates (latitude/longitude)
|
||||
- Geohash data (if available)
|
||||
- Creation/update timestamps
|
||||
|
||||
### Measurement Data
|
||||
- Water level readings
|
||||
- Discharge measurements
|
||||
- Discharge percentages
|
||||
- Timestamps
|
||||
- Station associations
|
||||
- Data quality status
|
||||
|
||||
## Supported SQLite Schemas
|
||||
|
||||
The migration tool automatically detects and handles various SQLite table structures:
|
||||
|
||||
### Modern Schema
|
||||
```sql
|
||||
-- Stations
|
||||
stations: id, station_code, station_name_th, station_name_en, latitude, longitude, geohash
|
||||
|
||||
-- Measurements
|
||||
water_measurements: timestamp, station_id, water_level, discharge, discharge_percent, status
|
||||
```
|
||||
|
||||
### Legacy Schema
|
||||
```sql
|
||||
-- Stations
|
||||
water_stations: station_id, station_code, station_name, lat, lon
|
||||
|
||||
-- Measurements
|
||||
measurements: timestamp, station_id, water_level, discharge, discharge_percent
|
||||
```
|
||||
|
||||
### Simple Schema
|
||||
```sql
|
||||
-- Any table with basic water level data
|
||||
-- The tool will adapt and map columns automatically
|
||||
```
|
||||
|
||||
## Migration Process
|
||||
|
||||
### Step 1: Database Connection
|
||||
- Connects to your SQLite database
|
||||
- Verifies PostgreSQL connection
|
||||
- Validates configuration
|
||||
|
||||
### Step 2: Schema Analysis
|
||||
- Scans SQLite tables and columns
|
||||
- Reports data counts
|
||||
- Identifies table structures
|
||||
|
||||
### Step 3: Station Migration
|
||||
- Extracts station metadata
|
||||
- Maps to PostgreSQL format
|
||||
- Handles missing data gracefully
|
||||
|
||||
### Step 4: Measurement Migration
|
||||
- Processes data in batches (1000 records at a time)
|
||||
- Converts timestamps correctly
|
||||
- Preserves all measurement values
|
||||
- Shows progress during migration
|
||||
|
||||
### Step 5: Verification
|
||||
- Compares record counts
|
||||
- Validates data integrity
|
||||
- Reports migration statistics
|
||||
|
||||
## Command Options
|
||||
|
||||
```bash
|
||||
# Basic migration (auto-detects SQLite file)
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py
|
||||
|
||||
# Specify SQLite database path
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py /path/to/database.db
|
||||
|
||||
# Dry run (analyze only, no migration)
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py --dry-run
|
||||
|
||||
# Custom batch size for large databases
|
||||
uv run python scripts/migrate_sqlite_to_postgres.py --batch-size 5000
|
||||
```
|
||||
|
||||
## Auto-Detection
|
||||
|
||||
The tool automatically searches for SQLite files in common locations:
|
||||
- `water_levels.db`
|
||||
- `water_monitoring.db`
|
||||
- `database.db`
|
||||
- `../water_levels.db`
|
||||
|
||||
## Migration Output
|
||||
|
||||
The tool provides detailed logging:
|
||||

SQLite to PostgreSQL Migration Tool
|
||||
========================================
|
||||
SQLite database: water_levels.db
|
||||
PostgreSQL: postgresql
|
||||
|
||||
Step 1: Connecting to databases...
|
||||
Connected to SQLite database: water_levels.db
|
||||
Connected to PostgreSQL database
|
||||
|
||||
Step 2: Analyzing SQLite database structure...
|
||||
Table 'stations': 8 columns, 25 rows
|
||||
Table 'water_measurements': 7 columns, 15420 rows
|
||||
|
||||
Step 3: Migrating station data...
|
||||
Migrated 25 stations
|
||||
|
||||
Step 4: Migrating measurement data...
|
||||
Found 15420 measurements to migrate
|
||||
Migrated 1000/15420 measurements
|
||||
Migrated 2000/15420 measurements
|
||||
...
|
||||
Successfully migrated 15420 measurements
|
||||
|
||||
Step 5: Verifying migration...
|
||||
SQLite stations: 25
|
||||
SQLite measurements: 15420
|
||||
PostgreSQL measurements retrieved: 15420
|
||||
Migrated stations: 25
|
||||
Migrated measurements: 15420
|
||||
|
||||
========================================
|
||||
MIGRATION COMPLETED
|
||||
========================================
|
||||
Duration: 0:02:15
|
||||
Stations migrated: 25
|
||||
Measurements migrated: 15420
|
||||
No errors encountered
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The migration tool is robust and handles:
|
||||
- **Missing tables** - Tries alternative table names
|
||||
- **Different column names** - Maps common variations
|
||||
- **Missing data** - Uses sensible defaults
|
||||
- **Invalid timestamps** - Attempts multiple date formats
|
||||
- **Connection issues** - Provides clear error messages
|
||||
- **Large datasets** - Processes in batches to avoid memory issues
|
||||
|
||||
## Log Files
|
||||
|
||||
Migration creates a detailed log file:
|
||||
- `migration.log` - Complete migration log
|
||||
- Shows all operations, errors, and statistics
|
||||
- Useful for troubleshooting
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**1. SQLite file not found**
|
||||
```
|
||||
SQLite database file not found. Please specify the path:
|
||||
python migrate_sqlite_to_postgres.py /path/to/database.db
|
||||
```
|
||||
**Solution**: Specify the correct path to your SQLite file
|
||||
|
||||
**2. PostgreSQL not configured**
|
||||
```
|
||||
Error: PostgreSQL not configured. Set DB_TYPE=postgresql in your .env file
|
||||
```
|
||||
**Solution**: Ensure your .env file has `DB_TYPE=postgresql`
|
||||
|
||||
**3. Connection failed**
|
||||
```
|
||||
Database connection error: connection refused
|
||||
```
|
||||
**Solution**: Check your PostgreSQL connection settings
|
||||
|
||||
**4. No tables found**
|
||||
```
|
||||
Could not analyze SQLite database structure
|
||||
```
|
||||
**Solution**: Verify your SQLite file contains water monitoring data
|
||||
|
||||
### Performance Tips
|
||||
|
||||
- **Large databases**: Use `--batch-size 5000` for faster processing
|
||||
- **Slow networks**: Reduce batch size to `--batch-size 100`
|
||||
- **Memory issues**: Process smaller batches
|
||||
|
||||
## After Migration
|
||||
|
||||
Once migration is complete:
|
||||
|
||||
1. **Verify data**:
|
||||
```bash
|
||||
make run-test
|
||||
make run-api
|
||||
```
|
||||
|
||||
2. **Check the web interface**: Latest readings should show your migrated data
|
||||
|
||||
3. **Backup your SQLite**: Keep the original file as backup
|
||||
|
||||
4. **Update configurations**: Remove SQLite references from configs
|
||||
|
||||
## Rollback
|
||||
|
||||
If you need to rollback:
|
||||
|
||||
1. **Clear PostgreSQL data**:
|
||||
```sql
|
||||
DELETE FROM water_measurements;
|
||||
DELETE FROM stations;
|
||||
```
|
||||
|
||||
2. **Switch back to SQLite**:
|
||||
```bash
|
||||
# In .env file
|
||||
DB_TYPE=sqlite
|
||||
WATER_DB_PATH=water_levels.db
|
||||
```
|
||||
|
||||
3. **Test the rollback**:
|
||||
```bash
|
||||
make run-test
|
||||
```
|
||||
|
||||
The migration tool is designed to be safe and can be run multiple times - it handles duplicates appropriately.
|
||||
|
||||
## Next Steps
|
||||
|
||||
After successful migration:
|
||||
- Set up automated backups for PostgreSQL
|
||||
- Configure monitoring and alerting
|
||||
- Consider data retention policies
|
||||
- Update documentation references

|
||||
|
||||
This is a standalone executable version of the Northern Thailand Ping River Monitor.
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. **Configure Database**: Edit `.env` file with your PostgreSQL settings
|
||||
2. **Test Connection**: Double-click `test.bat`
|
||||
3. **Start Monitoring**: Double-click `start.bat`
|
||||
4. **Web Interface**: Double-click `start-api.bat`
|
||||
|
||||
## Files Included
|
||||
|
||||
- `ping-river-monitor.exe` - Main executable
|
||||
- `.env` - Configuration file (EDIT THIS!)
|
||||
- `start.bat` - Start continuous monitoring
|
||||
- `start-api.bat` - Start web API server
|
||||
- `test.bat` - Run a test cycle
|
||||
- `status.bat` - Check system status
|
||||
- `README.md`, `POSTGRESQL_SETUP.md` - Documentation
|
||||
- `sql/` - Database initialization scripts
|
||||
|
||||
## Configuration
|
||||
|
||||
Edit `.env` file:
|
||||
```
|
||||
DB_TYPE=postgresql
|
||||
POSTGRES_HOST=your-server-ip
|
||||
POSTGRES_PORT=5432
|
||||
POSTGRES_DB=water_monitoring
|
||||
POSTGRES_USER=your-username
|
||||
POSTGRES_PASSWORD=your-password
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Command Line
|
||||
```cmd
|
||||
# Continuous monitoring
|
||||
ping-river-monitor.exe
|
||||
|
||||
# Single test run
|
||||
ping-river-monitor.exe --test
|
||||
|
||||
# Web API server
|
||||
ping-river-monitor.exe --web-api
|
||||
|
||||
# Check status
|
||||
ping-river-monitor.exe --status
|
||||
```
|
||||
|
||||
### Batch Files
|
||||
- Just double-click the `.bat` files for easy operation
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
1. **Database Connection Issues**
|
||||
- Check `.env` file settings
|
||||
- Verify PostgreSQL server is accessible
|
||||
- Test with `test.bat`
|
||||
|
||||
2. **Permission Issues**
|
||||
- Run as administrator if needed
|
||||
- Check firewall settings for API mode
|
||||
|
||||
3. **Log Files**
|
||||
- Check `water_monitor.log` for detailed logs
|
||||
- Logs are created in the same directory as the executable
|
||||
|
||||
