|
||||
|
||||
## Usage
|
||||
|
||||
### Searching Logs
|
||||
|
||||
#### Basic Search
|
||||
```logql
|
||||
{job="backend"}
|
||||
```
|
||||
|
||||
#### Filter by Level
|
||||
```logql
|
||||
{job="backend", level="error"}
|
||||
```
|
||||
|
||||
#### Search in Message
|
||||
```logql
|
||||
{job="backend"} |= "error"
|
||||
```
|
||||
|
||||
#### Security Logs
|
||||
```logql
|
||||
{job="security"} | json | action="LOGIN_ATTEMPT"
|
||||
```
|
||||
|
||||
#### Time Range
|
||||
Use Grafana's time picker to select a specific time range (e.g., last 1 hour, last 24 hours, custom range).
|
||||
|
||||
### Common Queries
|
||||
|
||||
**All errors in the last hour:**
|
||||
```logql
|
||||
{job=~"backend|security"} | json | level="error"
|
||||
```
|
||||
|
||||
**Failed login attempts:**
|
||||
```logql
|
||||
{job="security"} | json | action="LOGIN_ATTEMPT" | result="FAILURE"
|
||||
```
|
||||
|
||||
**Slow database queries:**
|
||||
```logql
|
||||
{job="backend"} | json | message=~".*query.*" | duration > 1000
|
||||
```
|
||||
|
||||
**Rate limiting events:**
|
||||
```logql
|
||||
{job="security"} | json | action="RATE_LIMIT_VIOLATION"
|
||||
```
|
||||
|
||||
**Request by request ID:**
|
||||
```logql
|
||||
{job="backend"} | json | requestId="abc123"
|
||||
```
|
||||
|
||||
### Live Tailing
|
||||
|
||||
1. Go to **Explore** in Grafana
|
||||
2. Select **Loki** datasource
|
||||
3. Enter your LogQL query
|
||||
4. Click **Live** button in the top right
|
||||
|
||||
This will stream logs in real-time as they arrive.
|
||||
|
||||
### Dashboard
|
||||
|
||||
The pre-configured dashboard includes:
|
||||
|
||||
1. **Log Volume by Level** - Time series chart showing log volume by level
|
||||
2. **Log Counts by Level** - Statistics showing error, warn, and info counts
|
||||
3. **Application Logs** - Main log viewer with filtering
|
||||
4. **Security Logs** - Dedicated security event viewer
|
||||
5. **Error Logs** - Quick view of all error logs
|
||||
|
||||
**Template Variables:**
|
||||
- `$job` - Filter by job (backend, security, postgres, etc.)
|
||||
- `$level` - Filter by log level (error, warn, info, debug)
|
||||
- `$search` - Free-text search filter
|
||||
|
||||
## Structured Logging Best Practices
|
||||
|
||||
### Application Code
|
||||
|
||||
Use Winston logger with structured fields:
|
||||
|
||||
```typescript
|
||||
import logger from './middleware/winstonLogger';
|
||||
|
||||
// Basic logging
|
||||
logger.info('User logged in', { userId: user.id });
|
||||
|
||||
// With request ID
|
||||
import { logWithRequestId } from './middleware/winstonLogger';
|
||||
|
||||
logWithRequestId('info', 'Processing request', req.id, {
|
||||
userId: user.id,
|
||||
action: 'fetch_data'
|
||||
});
|
||||
|
||||
// Error logging
|
||||
logger.error('Database connection failed', {
|
||||
error: err.message,
|
||||
stack: err.stack
|
||||
});
|
||||
```
|
||||
|
||||
### Log Levels
|
||||
|
||||
- **error** - Application errors, exceptions, failures
|
||||
- **warn** - Warning conditions, degraded performance
|
||||
- **info** - Important business events, state changes
|
||||
- **debug** - Detailed diagnostic information
|
||||
|
||||
### Security Events
|
||||
|
||||
Use the security logger for security-related events:
|
||||
|
||||
```typescript
|
||||
import { logSecurityEvent, SecurityActions } from './utils/securityLogger';
|
||||
|
||||
await logSecurityEvent({
|
||||
userId: user.discordId,
|
||||
action: SecurityActions.LOGIN_SUCCESS,
|
||||
result: 'SUCCESS',
|
||||
ipAddress: req.ip,
|
||||
userAgent: req.get('user-agent'),
|
||||
requestId: req.id
|
||||
});
|
||||
```
|
||||
|
||||
## Retention Policies
|
||||
|
||||
### Current Settings
|
||||
|
||||
- **Retention Period:** 30 days (720 hours)
|
||||
- **Compaction Interval:** 10 minutes
|
||||
- **Retention Delete Delay:** 2 hours
|
||||
- **Reject Old Samples:** 7 days
|
||||
|
||||
### Adjusting Retention
|
||||
|
||||
Edit `loki/loki-config.yml`:
|
||||
|
||||
```yaml
|
||||
limits_config:
|
||||
retention_period: 720h # Change this value (e.g., 1440h for 60 days)
|
||||
|
||||
table_manager:
|
||||
retention_period: 720h # Keep same as above
|
||||
|
||||
compactor:
|
||||
retention_enabled: true
|
||||
```
|
||||
|
||||
Then restart Loki:
|
||||
```bash
|
||||
docker-compose restart loki
|
||||
```
|
||||
|
||||
## Performance Tuning
|
||||
|
||||
### Ingestion Limits
|
||||
|
||||
Adjust in `loki/loki-config.yml`:
|
||||
|
||||
```yaml
|
||||
limits_config:
|
||||
ingestion_rate_mb: 15 # MB/s per tenant
|
||||
ingestion_burst_size_mb: 20 # Burst size
|
||||
per_stream_rate_limit: 3MB # Per stream rate
|
||||
per_stream_rate_limit_burst: 15MB # Per stream burst
|
||||
```
|
||||
|
||||
### Query Performance
|
||||
|
||||
```yaml
|
||||
limits_config:
|
||||
max_entries_limit_per_query: 5000 # Max entries returned
|
||||
max_streams_per_user: 10000 # Max streams per user
|
||||
```
|
||||
|
||||
### Cache Configuration
|
||||
|
||||
```yaml
|
||||
query_range:
|
||||
results_cache:
|
||||
cache:
|
||||
embedded_cache:
|
||||
enabled: true
|
||||
max_size_mb: 100 # Increase for better performance
|
||||
```
|
||||
|
||||
## Alerting
|
||||
|
||||
### Setting up Alerts
|
||||
|
||||
1. Create alert rules in `loki/alert-rules.yml`:
|
||||
|
||||
```yaml
|
||||
groups:
|
||||
- name: spywatcher-alerts
|
||||
interval: 1m
|
||||
rules:
|
||||
- alert: HighErrorRate
|
||||
expr: |
|
||||
sum(rate({job="backend", level="error"}[5m])) > 10
|
||||
for: 5m
|
||||
labels:
|
||||
severity: critical
|
||||
annotations:
|
||||
summary: "High error rate detected"
|
||||
description: "Error rate is {{ $value }} errors/sec"
|
||||
```
|
||||
|
||||
2. Configure Alertmanager URL in `loki/loki-config.yml`:
|
||||
|
||||
```yaml
|
||||
ruler:
|
||||
alertmanager_url: http://alertmanager:9093
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Logs not appearing in Grafana
|
||||
|
||||
1. **Check Promtail is running:**
|
||||
```bash
|
||||
docker ps | grep promtail
|
||||
docker logs spywatcher-promtail-dev
|
||||
```
|
||||
|
||||
2. **Check Loki is accepting logs:**
|
||||
```bash
|
||||
curl http://localhost:3100/ready
|
||||
```
|
||||
|
||||
3. **Verify log files exist:**
|
||||
```bash
|
||||
docker exec spywatcher-backend-dev ls -la /app/logs
|
||||
```
|
||||
|
||||
4. **Check Promtail configuration:**
|
||||
```bash
|
||||
docker exec spywatcher-promtail-dev cat /etc/promtail/config.yml
|
||||
```
|
||||
|
||||
### Loki storage issues
|
||||
|
||||
**Check disk usage:**
|
||||
```bash
|
||||
du -sh /var/lib/docker/volumes/discord-spywatcher_loki-data/
|
||||
```
|
||||
|
||||
**Force compaction:**
|
||||
```bash
|
||||
docker exec spywatcher-loki-dev wget -qO- http://localhost:3100/loki/api/v1/delete?query={job="backend"}&start=2024-01-01T00:00:00Z&end=2024-01-02T00:00:00Z
|
||||
```
|
||||
|
||||
### Performance issues
|
||||
|
||||
1. **Reduce retention period** - Lower retention in `loki-config.yml`
|
||||
2. **Increase resources** - Adjust memory limits in `docker-compose.prod.yml`
|
||||
3. **Reduce log volume** - Increase LOG_LEVEL to 'warn' or 'error'
|
||||
4. **Add sampling** - Implement log sampling in application code
|
||||
|
||||
## Monitoring the Logging Stack
|
||||
|
||||
### Loki Metrics
|
||||
|
||||
Available at: `http://localhost:3100/metrics`
|
||||
|
||||
**Key metrics:**
|
||||
- `loki_ingester_chunks_created_total` - Chunks created
|
||||
- `loki_ingester_bytes_received_total` - Bytes ingested
|
||||
- `loki_request_duration_seconds` - Query performance
|
||||
|
||||
### Promtail Metrics
|
||||
|
||||
Available at: `http://localhost:9080/metrics`
|
||||
|
||||
**Key metrics:**
|
||||
- `promtail_sent_entries_total` - Entries sent to Loki
|
||||
- `promtail_dropped_entries_total` - Dropped entries
|
||||
- `promtail_read_bytes_total` - Bytes read from logs
|
||||
|
||||
### Grafana Health
|
||||
|
||||
Available at: `http://localhost:3000/api/health`
|
||||
|
||||
## Integration with Other Tools
|
||||
|
||||
### Prometheus Integration
|
||||
|
||||
Loki integrates seamlessly with Prometheus for correlated metrics and logs:
|
||||
|
||||
1. Configure Prometheus datasource in Grafana
|
||||
2. Use derived fields to link logs to traces
|
||||
3. Create unified dashboards with both metrics and logs
|
||||
|
||||
### Sentry Integration
|
||||
|
||||
Logs can reference Sentry issues:
|
||||
|
||||
```typescript
|
||||
logger.error('Unhandled exception', {
|
||||
sentryEventId: sentryEventId,
|
||||
error: err.message
|
||||
});
|
||||
```
|
||||
|
||||
Search in Loki:
|
||||
```logql
|
||||
{job="backend"} | json | sentryEventId="abc123"
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Access Control
|
||||
|
||||
1. **Change default Grafana password** - Set `GRAFANA_ADMIN_PASSWORD`
|
||||
2. **Enable HTTPS** - Configure SSL/TLS for Grafana
|
||||
3. **Network isolation** - Keep Loki/Promtail in private network
|
||||
4. **Authentication** - Enable OAuth or LDAP authentication in Grafana
|
||||
5. **Enable Loki authentication** - For production, set `auth_enabled: true` in `loki/loki-config.yml` and configure authentication methods
|
||||
|
||||
**Note:** Loki authentication is disabled by default for development/testing. For production deployments, enable authentication to prevent unauthorized access to log data. See [Loki authentication documentation](https://grafana.com/docs/loki/latest/configuration/#server).
|
||||
|
||||
### Log Sanitization
|
||||
|
||||
Winston logger automatically sanitizes sensitive data:
|
||||
- Passwords
|
||||
- Tokens (access, refresh, API keys)
|
||||
- OAuth scopes
|
||||
- Email addresses
|
||||
|
||||
See: `backend/src/utils/securityLogger.ts`
|
||||
|
||||
### Compliance
|
||||
|
||||
- **GDPR** - Logs containing PII are automatically sanitized
|
||||
- **Data Retention** - 30-day retention complies with most regulations
|
||||
- **Audit Trail** - Security logs provide compliance audit trail
|
||||

# Centralized Logging Quick Start Guide
|
||||
|
||||
This guide will help you get started with the centralized logging system in Discord SpyWatcher.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker and Docker Compose installed
|
||||
- Discord SpyWatcher repository cloned
|
||||
- Environment variables configured (see `.env.example`)
|
||||
|
||||
## Step 1: Start the Logging Stack
|
||||
|
||||
### Development Environment
|
||||
|
||||
```bash
|
||||
# Start all services including logging stack
|
||||
docker compose -f docker-compose.dev.yml up -d
|
||||
|
||||
# Or start only the logging stack
|
||||
docker compose -f docker-compose.dev.yml up -d loki promtail grafana
|
||||
```
|
||||
|
||||
### Production Environment
|
||||
|
||||
```bash
|
||||
docker compose -f docker-compose.prod.yml up -d
|
||||
```
|
||||
|
||||
## Step 2: Verify Services are Running
|
||||
|
||||
```bash
|
||||
# Check all containers are running
|
||||
docker ps | grep -E 'loki|promtail|grafana'
|
||||
|
||||
# Expected output (3 containers):
|
||||
# spywatcher-loki-dev grafana/loki:2.9.3
|
||||
# spywatcher-promtail-dev grafana/promtail:2.9.3
|
||||
# spywatcher-grafana-dev grafana/grafana:10.2.3
|
||||
```
|
||||
|
||||
## Step 3: Access Grafana
|
||||
|
||||
1. Open your browser to: **http://localhost:3000**
|
||||
2. Login with default credentials:
|
||||
- **Username:** `admin`
|
||||
- **Password:** `admin`
|
||||
3. You'll be prompted to change the password on first login
|
||||
|
||||
## Step 4: View Logs
|
||||
|
||||
### Option 1: Using the Pre-configured Dashboard
|
||||
|
||||
1. Navigate to **Dashboards** (left sidebar, four squares icon)
|
||||
2. Click on **Spywatcher - Log Aggregation**
|
||||
3. You should see:
|
||||
- Log volume chart
|
||||
- Log level statistics
|
||||
- Application logs
|
||||
- Security logs
|
||||
- Error logs
|
||||
|
||||
### Option 2: Using Explore
|
||||
|
||||
1. Click **Explore** (compass icon in the left sidebar)
|
||||
2. Select **Loki** as the datasource (should be selected by default)
|
||||
3. Enter a LogQL query, for example:
|
||||
```logql
|
||||
{job="backend"}
|
||||
```
|
||||
4. Click **Run query** or press `Shift + Enter`
|
||||
|
||||
## Step 5: Filter and Search Logs
|
||||
|
||||
### Using Dashboard Variables
|
||||
|
||||
In the **Spywatcher - Log Aggregation** dashboard:
|
||||
|
||||
1. **Job** dropdown - Select which service to view (backend, security, postgres, etc.)
|
||||
2. **Level** dropdown - Filter by log level (error, warn, info, debug)
|
||||
3. **Search** box - Enter text to search within log messages
|
||||
|
||||
### Using LogQL Queries
|
||||
|
||||
In **Explore**, try these queries:
|
||||
|
||||
**All errors:**
|
||||
```logql
|
||||
{job="backend"} | json | level="error"
|
||||
```
|
||||
|
||||
**Failed login attempts:**
|
||||
```logql
|
||||
{job="security"} | json | action="LOGIN_ATTEMPT" | result="FAILURE"
|
||||
```
|
||||
|
||||
**Logs from the last hour:**
|
||||
Use the time picker in the top-right corner
|
||||
|
||||
**Search for specific text:**
|
||||
```logql
|
||||
{job="backend"} |= "database connection"
|
||||
```
|
||||
|
||||
## Step 6: Monitor Log Collection
|
||||
|
||||
### Check Promtail is Collecting Logs
|
||||
|
||||
```bash
|
||||
# View Promtail logs
|
||||
docker logs spywatcher-promtail-dev
|
||||
|
||||
# Check Promtail metrics
|
||||
curl http://localhost:9080/metrics | grep promtail_sent_entries_total
|
||||
```
|
||||
|
||||
### Check Loki is Receiving Logs
|
||||
|
||||
```bash
|
||||
# Check Loki health
|
||||
curl http://localhost:3100/ready
|
||||
|
||||
# Check Loki metrics
|
||||
curl http://localhost:3100/metrics | grep loki_ingester_bytes_received_total
|
||||
```
|
||||
|
||||
## Common Issues and Solutions
|
||||
|
||||
### Issue: No logs appearing in Grafana
|
||||
|
||||
**Solution 1: Check backend logs directory exists**
|
||||
```bash
|
||||
docker exec spywatcher-backend-dev ls -la /app/logs
|
||||
```
|
||||
|
||||
**Solution 2: Verify Promtail is running and configured correctly**
|
||||
```bash
|
||||
docker logs spywatcher-promtail-dev
|
||||
docker exec spywatcher-promtail-dev cat /etc/promtail/config.yml
|
||||
```
|
||||
|
||||
**Solution 3: Restart services**
|
||||
```bash
|
||||
docker compose -f docker-compose.dev.yml restart promtail loki
|
||||
```
|
||||
|
||||
### Issue: Grafana shows "Cannot connect to Loki"
|
||||
|
||||
**Solution: Check Loki is running and accessible**
|
||||
```bash
|
||||
# Check Loki status
|
||||
docker ps | grep loki
|
||||
|
||||
# Test Loki endpoint from Grafana container
|
||||
docker exec spywatcher-grafana-dev wget -qO- http://loki:3100/ready
|
||||
```
|
||||
|
||||
### Issue: Permission denied accessing Docker socket
|
||||
|
||||
**Solution: Add user to docker group (Linux)**
|
||||
```bash
|
||||
sudo usermod -aG docker $USER
|
||||
# Log out and back in for changes to take effect
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Customize Log Retention** - See [LOGGING.md](../LOGGING.md#retention-policies)

3. **Grafana 10.2.3**
|
||||
- Visualization and search UI
|
||||
- Pre-provisioned datasources
|
||||
- Pre-configured dashboard
|
||||
- Port: 3000
|
||||
|
||||
### Log Sources
|
||||
|
||||
The following services have their logs aggregated:
|
||||
|
||||
- **Backend** - Application logs, errors, info (`/logs/backend/*.log`)
|
||||
- **Security** - Auth events, security incidents (`/logs/backend/security.log`)
|
||||
- **PostgreSQL** - Database logs (`/var/log/postgresql/*.log`)
|
||||
- **Redis** - Cache operations (Docker logs)
|
||||
- **PgBouncer** - Connection pooling (Docker logs)
|
||||
- **Nginx** - HTTP access/error logs (Docker logs)
|
||||
- **All Docker containers** - Stdout/stderr logs
|
||||
|
||||
### Data Flow
|
||||
|
||||
```
|
||||
Services → Winston/Console → Log Files/Docker → Promtail → Loki → Grafana
|
||||
```
|
||||
|
||||

## Configuration Highlights
|
||||
|
||||
### Retention Policy
|
||||
|
||||
**Duration:** 30 days (720 hours)
|
||||
**Reasoning:**
|
||||
- Balances storage costs with troubleshooting needs
|
||||
- Complies with most data retention regulations
|
||||
- Sufficient for incident investigation
|
||||
- Can be easily adjusted in `loki/loki-config.yml`
|
||||
|
||||
### Ingestion Limits
|
||||
|
||||
- **Rate:** 15 MB/s per tenant
|
||||
- **Burst:** 20 MB
|
||||
- **Per Stream Rate:** 3 MB/s
|
||||
- **Per Stream Burst:** 15 MB
|
||||
|
||||
These limits prevent log storms from overwhelming the system.
|
||||
|
||||
### Query Limits
|
||||
|
||||
- **Max Entries per Query:** 5000
|
||||
- **Max Streams per User:** 10000
|
||||
|
||||
Prevents expensive queries from impacting performance.
|
||||
|
||||
## Dashboard Features
|
||||
|
||||
The **Spywatcher - Log Aggregation** dashboard includes:
|
||||
|
||||
1. **Log Volume Chart** - Time series showing log volume by level
|
||||
2. **Log Count Stats** - Quick stats for error/warn/info counts
|
||||
3. **Application Logs** - Main log viewer with real-time updates
|
||||
4. **Security Logs** - Dedicated security event viewer
|
||||
5. **Error Logs** - Quick access to all errors
|
||||
|
||||
**Template Variables:**
|
||||
- `$job` - Filter by service (backend, security, postgres, etc.)
|
||||
- `$level` - Filter by log level (error, warn, info, debug)
|
||||
- `$search` - Free-text search across all logs
|
||||
|
||||
## LogQL Query Examples
|
||||
|
||||
```logql
|
||||
# All logs from backend
|
||||
{job="backend"}
|
||||
|
||||
# Only errors
|
||||
{job="backend", level="error"}
|
||||
|
||||
# Failed login attempts
|
||||
{job="security"} | json | action="LOGIN_ATTEMPT" | result="FAILURE"
|
||||
|
||||
# Search for specific text
|
||||
{job="backend"} |= "database connection"
|
||||
|
||||
# Rate limiting violations
|
||||
{job="security"} | json | action="RATE_LIMIT_VIOLATION"
|
||||
|
||||
# Logs by request ID
|
||||
{job="backend"} | json | requestId="abc123"
|
||||
```
|
||||
|
||||
## Resource Requirements
|
||||
|
||||
### Development Environment
|
||||
- **Loki:** 300-500 MB RAM
|
||||
- **Promtail:** 50-100 MB RAM
|
||||
- **Grafana:** 200-300 MB RAM
|
||||
- **Total:** ~700 MB RAM, 10 GB disk (for 30-day retention)
|
||||
|
||||
### Production Environment
|
||||
- **Loki:** 512 MB RAM (limit)
|
||||
- **Promtail:** 128 MB RAM (limit)
|
||||
- **Grafana:** 512 MB RAM (limit)
|
||||
- **Total:** ~1.2 GB RAM, 50 GB disk (recommended)
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Query Performance
|
||||
- Simple queries: <100ms
|
||||
- Complex aggregations: <1s
|
||||
- Full-text search: <2s (depending on time range)
|
||||
|
||||
### Ingestion Performance
|
||||
- Sustained: 15 MB/s
|
||||
- Burst: 20 MB/s
|
||||
- Latency: <1s from log generation to Grafana
|
||||
|
||||
### Storage Efficiency
|
||||
- Compression ratio: ~10:1
|
||||
- Typical daily volume: 1-5 GB (compressed)
|
||||
- 30-day storage: 30-150 GB
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Data Sanitization
|
||||
Winston logger automatically sanitizes:
|
||||
- Passwords
|
||||
- Access/refresh tokens
|
||||
- API keys
|
||||
- OAuth scopes
|
||||
- Email addresses
|
||||
|
||||
See: `backend/src/utils/securityLogger.ts`
|
||||
|
||||
### Access Control
|
||||
- Default Grafana credentials: `admin/admin`
|
||||
- **Must be changed on first login**
|
||||
- Environment variables: `GRAFANA_ADMIN_USER`, `GRAFANA_ADMIN_PASSWORD`
|
||||
|
||||
### Network Security
|
||||
- Loki/Promtail not exposed publicly (internal network only)
|
||||
- Grafana can be exposed via reverse proxy with SSL
|
||||
- Log data encrypted at rest (Docker volume encryption)
|
||||
|
||||
## Monitoring the Stack
|
||||
|
||||
### Health Checks
|
||||
|
||||
**Loki:**
|
||||
```bash
|
||||
curl http://localhost:3100/ready
|
||||
curl http://localhost:3100/metrics
|
||||
```
|
||||
|
||||
**Promtail:**
|
||||
```bash
|
||||
curl http://localhost:9080/metrics
|
||||
docker logs spywatcher-promtail-dev
|
||||
```
|
||||
|
||||
**Grafana:**
|
||||
```bash
|
||||
curl http://localhost:3000/api/health
|
||||
```
|
||||
|
||||
### Key Metrics to Monitor
|
||||
|
||||
1. **loki_ingester_bytes_received_total** - Ingestion rate
|
||||
2. **promtail_sent_entries_total** - Entries shipped
|
||||
3. **promtail_dropped_entries_total** - Dropped entries (should be 0)
|
||||
4. **loki_request_duration_seconds** - Query performance
|
||||
|
||||

|
||||
|
||||
## Troubleshooting Guide
|
||||
|
||||
### Issue: Logs not appearing
|
||||
|
||||
**Check:**
|
||||
1. Promtail is running: `docker ps | grep promtail`
|
||||
2. Log files exist: `docker exec backend ls /app/logs`
|
||||
3. Promtail can read logs: `docker logs promtail`
|
||||
4. Loki is receiving data: `curl localhost:3100/metrics | grep ingester`
|
||||
|
||||
### Issue: High disk usage
|
||||
|
||||
**Solution:**
|
||||
1. Reduce retention: Edit `loki/loki-config.yml`
|
||||
2. Increase compression: Enable more aggressive compaction
|
||||
3. Reduce log level: Set `LOG_LEVEL=warn` or `LOG_LEVEL=error`
|
||||
|
||||
### Issue: Query performance slow
|
||||
|
||||
**Solution:**
|
||||
1. Narrow time range
|
||||
2. Add more specific labels to query
|
||||
3. Increase cache size in `loki-config.yml`
|
||||
4. Use streaming mode for large results
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Potential Improvements
|
||||
|
||||
1. **Alerting**
|
||||
- Configure Alertmanager integration
|
||||
- Create alert rules for critical errors
|
||||

|
||||
- Enable log replay from archives
|
||||
|
||||
4. **Advanced Analytics**
|
||||
- Create custom Grafana dashboards
|
||||
- Implement log-based metrics
|
||||

# Promtail Configuration
|
||||
|
||||
This directory contains the configuration for Promtail, the log collection agent.
|
||||
|
||||
## Files
|
||||
|
||||
- `promtail-config.yml` - Main Promtail configuration file
|
||||
|
||||
## Log Sources
|
||||
|
||||
Promtail collects logs from:
|
||||
|
||||
1. **Backend Application Logs** (`/logs/backend/*.log`)
|
||||
- JSON formatted logs
|
||||
- Labels: job, service, level
|
||||
|
||||
2. **Security Logs** (`/logs/backend/security.log`)
|
||||
- Security events
|
||||
- Labels: job, level, action, result
|
||||
|
||||
3. **PostgreSQL Logs** (`/var/log/postgresql/*.log`)
|
||||
- Database logs
|
||||
- Labels: job, service
|
||||
|
||||
4. **Docker Container Logs** (via Docker socket)
|
||||
- Redis, PgBouncer, Nginx, etc.
|
||||
- Labels: container, service, stream
|
||||
|
||||
## Pipeline Stages
|
||||
|
||||
For structured logs (JSON):
|
||||
1. **JSON parsing** - Extract fields from JSON
|
||||
2. **Label extraction** - Create Loki labels
|
||||
3. **Timestamp parsing** - Parse timestamp field
|
||||
4. **Output formatting** - Format log message
|
||||
|
||||
## Ports
|
||||
|
||||
- `9080` - HTTP API (metrics)
|
||||
|
||||
## Customization
|
||||
|
||||
To add a new log source:
|
||||
|
||||
```yaml
|
||||
scrape_configs:
|
||||
- job_name: my_service
|
||||
static_configs:
|
||||
- targets:
|
||||
- localhost
|
||||
labels:
|
||||
job: my_service
|
||||
service: my-service-name
|
||||
__path__: /path/to/logs/*.log
|
||||
```
