Grafana dashboard

Grafana dashboard

A Grafana dashboard JSON file is downloadable from Settings. It is pre-wired to Companion's Prometheus metrics and includes panels for:

• Download/upload throughput per server (bar gauge)
• Latency, jitter, packet loss, DNS (bar gauge)
• Confidence index and profile score (bar gauge)
• Errors by type (donut chart)
• Continuous observation: enabled/running state and cycle progress
• Rotation pools: pool count, active automatic pools, last/next rotation
• Summary table of all servers
• Automatic Grafana filters by provider, VPN profile and server

Available Prometheus metrics

In addition to the base metrics (avg_dl, avg_ul, avg_latency, test_count, failure_count, enabled, active), Companion exposes:

Metric	Description
gluetun_companion_server_avg_jitter_ms	Average jitter (sidecar tests only)
gluetun_companion_server_avg_loss_pct	Average packet loss
gluetun_companion_server_avg_dns_ms	Average DNS latency
gluetun_companion_server_confidence	Confidence index: 0=LOW, 1=MEDIUM, 2=HIGH
gluetun_companion_server_score	Active profile score [0–1]
gluetun_companion_server_last_benchmark_ts_seconds	Unix timestamp of the last test
gluetun_companion_benchmark_total_servers, *_done_servers, *_remaining_servers	Current benchmark/observation cycle progress
gluetun_companion_continuous_observation_enabled, *_running	Continuous observation state
gluetun_companion_rotation_pools_total, *_enabled, *_auto_enabled	Global pool counters
gluetun_companion_rotation_pool_last_speed_mbps, *_last_rotation_timestamp_seconds, *_next_rotation_timestamp_seconds	Per-pool metrics (pool)
gluetun_companion_errors_total{type}	Error counter by type: timeout, connection, vpn, other
