# Prometheus Metrics for Vaultwarden |
|||
|
|||
This document describes how to enable and configure Prometheus metrics in Vaultwarden. |
|||
|
|||
## Configuration |
|||
|
|||
### Environment Variables |
|||
|
|||
- `ENABLE_METRICS`: Set to `true` to enable the metrics endpoint (default: `false`) |
|||
- `METRICS_TOKEN`: Optional token to secure the /metrics endpoint (default: none - public access) |
|||
|
|||
### Examples |
|||
|
|||
#### Enable metrics without authentication (development) |
|||
```bash |
|||
ENABLE_METRICS=true |
|||
``` |
|||
|
|||
#### Enable metrics with token authentication (production) |
|||
```bash |
|||
ENABLE_METRICS=true |
|||
METRICS_TOKEN=your-secret-token |
|||
``` |
|||
|
|||
#### Enable metrics with Argon2 hashed token (most secure) |
|||
```bash |
|||
ENABLE_METRICS=true |
|||
METRICS_TOKEN='$argon2id$v=19$m=65540,t=3,p=4$...' |
|||
``` |
|||
|
|||
## Build Configuration |
|||
|
|||
To enable metrics support, compile with the `enable_metrics` feature: |
|||
|
|||
```bash |
|||
cargo build --features enable_metrics |
|||
``` |
|||
|
|||
Without this feature, all metrics functions become no-ops and the endpoint is not available. |
|||
|
|||
## Usage |
|||
|
|||
When enabled, metrics are available at: |
|||
- `/metrics` (if no token configured) |
|||
- `/metrics?token=your-token` (with token as query parameter) |
|||
- `/metrics` with `Authorization: Bearer your-token` header |
|||
|
|||
## Metrics Categories |
|||
|
|||
### HTTP Metrics |
|||
- `vaultwarden_http_requests_total`: Total number of HTTP requests by method, path, and status |
|||
- `vaultwarden_http_request_duration_seconds`: HTTP request duration histograms |
|||
|
|||
### Database Metrics |
|||
- `vaultwarden_db_connections_active`: Number of active database connections |
|||
- `vaultwarden_db_connections_idle`: Number of idle database connections |
|||
- `vaultwarden_db_query_duration_seconds`: Database query duration histograms |
|||
|
|||
### Authentication Metrics |
|||
- `vaultwarden_auth_attempts_total`: Total authentication attempts by method and status |
|||
- `vaultwarden_user_sessions_active`: Number of active user sessions |
|||
|
|||
### Business Metrics |
|||
- `vaultwarden_users_total`: Total number of users by status (enabled/disabled) |
|||
- `vaultwarden_organizations_total`: Total number of organizations |
|||
- `vaultwarden_vault_items_total`: Total number of vault items by type and organization |
|||
- `vaultwarden_collections_total`: Total number of collections per organization |
|||
|
|||
### System Metrics |
|||
- `vaultwarden_uptime_seconds`: Application uptime in seconds |
|||
- `vaultwarden_build_info`: Build information (version, revision, branch) |
|||
|
|||
## Security Considerations |
|||
|
|||
- **Disable by default**: Metrics are disabled unless explicitly enabled |
|||
- **Token protection**: Use a strong, unique token in production environments |
|||
- **Argon2 hashing**: For maximum security, use Argon2-hashed tokens |
|||
- **Network security**: Consider restricting access to the metrics endpoint at the network level |
|||
- **Rate limiting**: The endpoint uses existing Vaultwarden rate limiting mechanisms |
|||
|
|||
## Integration with Monitoring Systems |
|||
|
|||
### Prometheus Configuration |
|||
|
|||
```yaml |
|||
scrape_configs: |
|||
- job_name: 'vaultwarden' |
|||
static_configs: |
|||
- targets: ['localhost:8080'] |
|||
metrics_path: '/metrics' |
|||
bearer_token: 'your-secret-token' # If using token authentication |
|||
scrape_interval: 30s |
|||
``` |
|||
|
|||
### Grafana Dashboard |
|||
|
|||
The metrics can be visualized in Grafana using the standard Prometheus data source. Common queries: |
|||
|
|||
- Request rate: `rate(vaultwarden_http_requests_total[5m])` |
|||
- Error rate: `rate(vaultwarden_http_requests_total{status=~"4..|5.."}[5m])` |
|||
- Active users: `vaultwarden_users_total{status="enabled"}` |
|||
- Database connections: `vaultwarden_db_connections_active` |
|||
|
|||
## Troubleshooting |
|||
|
|||
### Metrics endpoint not found (404) |
|||
- Ensure `ENABLE_METRICS=true` is set |
|||
- Verify the application was compiled with `--features enable_metrics` |
|||
- Check application logs for metrics initialization messages |
|||
|
|||
### Authentication errors (401) |
|||
- Verify the `METRICS_TOKEN` is correctly configured |
|||
- Ensure the token in requests matches the configured token |
|||
- Check for whitespace or encoding issues in token values |
|||
|
|||
### Missing metrics data |
|||
- Metrics are populated as the application handles requests |
|||
- Some business metrics require database queries and may take time to populate |
|||
- Check application logs for any metrics collection errors |
|||
|
|||
## Performance Impact |
|||
|
|||
- Metrics collection has minimal performance overhead |
|||
- Database metrics queries are run only when the metrics endpoint is accessed |
|||
- Consider the frequency of metrics scraping in high-traffic environments |

Create a Grafana dashboard with these panel queries: |
|||
|
|||
#### Request Rate Panel |
|||
```promql |
|||
sum(rate(vaultwarden_http_requests_total[5m])) by (path) |
|||
``` |
|||
|
|||
#### Error Rate Panel |
|||
```promql |
|||
sum(rate(vaultwarden_http_requests_total{status=~"4..|5.."}[5m])) / |
|||
sum(rate(vaultwarden_http_requests_total[5m])) * 100 |
|||
``` |
|||
|
|||
#### Response Time Panel |
|||
```promql |
|||
histogram_quantile(0.95, |
|||
sum(rate(vaultwarden_http_request_duration_seconds_bucket[5m])) by (le) |
|||
) |
|||
``` |
|||
|
|||
#### Active Users Panel |
|||
```promql |
|||
vaultwarden_users_total{status="enabled"} |
|||
``` |
|||
|
|||
#### Database Connections Panel |
|||
```promql |
|||
vaultwarden_db_connections_active |
|||
``` |
|||
|
|||
#### Vault Items Panel |
|||
```promql |
|||
sum by (type) (vaultwarden_vault_items_total) |
|||
``` |
|||
|
|||
### Import Dashboard |
|||
|
|||
1. Download the dashboard JSON from `examples/grafana-dashboard.json` |
|||
2. In Grafana, go to Dashboards → Import |
|||
3. Upload the JSON file |
|||
4. Configure the Prometheus data source |
|||
|
|||
## Alerting Rules |
|||
|
|||
### Prometheus Alerting Rules |
|||
|
|||
```yaml |
|||
# vaultwarden_rules.yml |
|||

|||
|
|||
# Database connection issues |
|||
- alert: VaultwardenDatabaseConnections |
|||

|||
) * 100 > 20 |
|||
for: 5m |
|||
labels: |
|||
severity: warning |
|||
annotations: |
|||
summary: "High authentication failure rate" |
|||
description: "{{ $value }}% of authentication attempts are failing" |
|||
``` |
|||
|
|||
## Security Considerations |
|||
|
|||
### Token Security |
|||
|
|||
1. **Use strong tokens**: Generate cryptographically secure random tokens |
|||
2. **Use Argon2 hashing**: For production environments, use hashed tokens |
|||
3. **Rotate tokens regularly**: Change metrics tokens periodically |
|||
4. **Limit network access**: Restrict metrics endpoint access to monitoring systems |
|||
|
|||
### Network Security |
|||
|
|||
```nginx |
|||
# Nginx configuration example |
|||
location /metrics { |
|||
# Restrict to monitoring systems only |
|||
allow 10.0.0.0/8; # Private network |
|||
allow 192.168.1.100; # Prometheus server |
|||
deny all; |
|||
|
|||
proxy_pass http://vaultwarden:8080; |
|||
proxy_set_header Authorization "Bearer your-secret-token"; |
|||
} |
|||
``` |
|||
|
|||
### Firewall Rules |
|||
|
|||
```bash |
|||
# UFW rules example |
|||
ufw allow from 192.168.1.100 to any port 8080 comment "Prometheus metrics" |
|||
ufw deny 8080 comment "Block metrics from other sources" |
|||
``` |
|||
|
|||
## Troubleshooting |
|||
|
|||
### Common Issues |
|||
|
|||
#### 1. Metrics Endpoint Returns 404 |
|||
|
|||
**Problem**: `/metrics` endpoint not found |
|||
|
|||
**Solutions**: |
|||
- Ensure `ENABLE_METRICS=true` is set |
|||
- Verify compilation with `--features enable_metrics` |
|||
- Check application logs for metrics initialization |
|||
|
|||
#### 2. Authentication Errors (401) |
|||
|
|||
**Problem**: Metrics endpoint returns unauthorized |
|||
|
|||
**Solutions**: |
|||
- Verify `METRICS_TOKEN` configuration |
|||
- Check token format and encoding |
|||
- Ensure Authorization header is correctly formatted |
|||
|
|||
#### 3. Missing Metrics Data |
|||
|
|||
**Problem**: Some metrics are not appearing |
|||
|
|||
**Solutions**: |
|||
- Business metrics require database queries - wait for first scrape |
|||
- HTTP metrics populate only after requests are made |
|||
- Check application logs for metric collection errors |
|||
|
|||
#### 4. High Cardinality Issues |
|||
|
|||
**Problem**: Too many metric series causing performance issues |
|||
|
|||
**Solutions**: |
|||
- Path normalization is automatic but verify it's working |
|||
- Consider reducing scrape frequency |
|||
- Monitor Prometheus memory usage |
|||
|
|||
### Diagnostic Commands |
|||
|
|||
```bash |
|||
# Test metrics endpoint |
|||
curl -v -H "Authorization: Bearer your-token" http://localhost:8080/metrics |
|||
|
|||
# Check metrics format |
|||
curl -H "Authorization: Bearer your-token" http://localhost:8080/metrics | head -20 |
|||
|
|||
# Verify Prometheus can scrape |
|||
curl http://prometheus:9090/api/v1/targets |
|||
|
|||
# Check for metric ingestion |
|||
curl -g 'http://prometheus:9090/api/v1/query?query=up{job="vaultwarden"}' |
|||
``` |
|||
|
|||
### Performance Tuning |
|||
|
|||
#### Prometheus Configuration |
|||
|
|||
```yaml |
|||
# Optimize for high-frequency scraping |
|||
global: |
|||
scrape_interval: 15s # More frequent scraping |
|||
scrape_timeout: 10s # Allow time for DB queries |
|||
|
|||
# Retention policy |
|||
storage: |
|||
tsdb: |
|||
retention.time: 30d # Keep 30 days of data |
|||
retention.size: 10GB # Limit storage usage |
|||
``` |
|||
|
|||
#### Vaultwarden Optimization |
|||
|
|||
```bash |
|||
# Reduce metrics collection overhead |
|||
ENABLE_METRICS=true |
|||
METRICS_TOKEN=your-token |
|||
DATABASE_MAX_CONNS=10 # Adequate for metrics queries |
|||
``` |
|||
|
|||
### Monitoring the Monitor |
|||
|
|||
Set up monitoring for your monitoring stack: |
|||
|
|||
```yaml |
|||
# Monitor Prometheus itself |
|||
- alert: PrometheusDown |
|||
expr: up{job="prometheus"} == 0 |
|||
for: 5m |
|||
|
|||
# Monitor scrape failures |
|||
- alert: VaultwardenScrapeFailure |
|||
expr: up{job="vaultwarden"} == 0 |
|||
for: 2m |
|||
``` |
|||
|
|||
This comprehensive monitoring setup will provide full observability into your Vaultwarden instance's health, performance, and usage patterns. |
