Prometheus Metrics (/metrics)

OpsMini ships a node_exporter-compatible /metrics endpoint — no extra node_exporter needed.

Enable & Auth

Configure in config.yaml (enabled by default):

metrics:
  enabled: true      # enable /metrics endpoint
  user: ""           # Basic auth username; empty = no auth
  password: ""       # Basic auth password

Credential priority: the username/password in panel "Settings → Metrics Export" override the config file; an empty username means no auth.

Prometheus Configuration

scrape_configs:
  - job_name: 'opsmini'
    static_configs:
      - targets: ['<host>:8888']
    metrics_path: '/metrics'
    basic_auth:            # required when auth is enabled
      username: 'monitor'
      password: '<password>'

Metric Families

Aligned with node_exporter core metrics, ready for community Node dashboards:

Family	Description
node_cpu_seconds_total{cpu,mode}	Cumulative seconds per core/mode
node_memory_MemTotal_bytes etc.	Memory Total / Free / Available / Buffers / Cached
node_filesystem_size_bytes{mountpoint}	Filesystem capacity / free / usage
node_network_receive_bytes_total{device}	Per-interface traffic
node_load1 / node_load5 / node_load15	Load average
node_uname_info / node_boot_time_seconds	Host info and boot time

Notes

• Reuses data already collected by gopsutil, output in Prometheus text format.
• Keeps the single-binary delivery; no embedded node_exporter process.
• With server.secret_entry set, the endpoint also mounts under the prefix (e.g. /opsmini_panel/metrics).
