# 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 |

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

|
|

# 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 |
