# Vaultwarden Metrics Configuration Examples |
|||
# Copy these variables to your .env file or set as environment variables |
|||
|
|||
# ============================================ |
|||
# Basic Metrics Configuration |
|||
# ============================================ |
|||
|
|||
# Enable metrics endpoint (disabled by default) |
|||
ENABLE_METRICS=true |
|||
|
|||
# ============================================ |
|||
# Security Configuration |
|||
# ============================================ |
|||
|
|||
# Option 1: No authentication (DEVELOPMENT ONLY) |
|||
# Leave METRICS_TOKEN unset for public access |
|||
# WARNING: This exposes potentially sensitive information |
|||
|
|||
# Option 2: Plain text token (basic security) |
|||
# METRICS_TOKEN=your-secret-metrics-token-here |
|||
|
|||
# Option 3: Argon2 hashed token (recommended for production) |
|||
# Generate with: vaultwarden hash |
|||
# METRICS_TOKEN='$argon2id$v=19$m=65540,t=3,p=4$...' |
|||
|

# ============================================ |

# Prometheus Scrape Configuration |
|||
# ============================================ |
|||
|

# In your prometheus.yml: |

# |

# scrape_configs: |
|||
# - job_name: 'vaultwarden' |
|||
# static_configs: |
|||
# - targets: ['localhost:8080'] |
|||
# metrics_path: '/metrics' |
|||
# # For token authentication: |
|||
# bearer_token: 'your-secret-metrics-token-here' |
|||
# # OR use query parameter: |
|||
# # params: |
|||
# # token: ['your-secret-metrics-token-here'] |
|||
# scrape_interval: 30s |
|||
# scrape_timeout: 10s |
|||
|
|||
# ============================================ |
|||
# Build Configuration |
|||
# ============================================ |
|||
|

# To enable metrics support, compile with: |

# cargo build --features enable_metrics --release |
