Ship logs and metrics
from any server.
No dependencies.

uplog is a single binary that tails your log files, collects system metrics, and ships structured JSON to any backend over HTTP. Configure it in five lines of TOML.

How it works

Tail

Log collection

Watches your log files. Every new line becomes a structured LogLine with source, timestamp, and message.

Collect

Metric collection

Snapshots CPU usage, memory, disk, and network counters on your configured interval.

Ship

HTTP shipping

Batches everything into a single JSON payload and POSTs it to your endpoint. Works with any backend.

Five lines of config

[agent]
id = "prod-api-01"

[logs]
paths = ["/var/log/app.log", "/var/log/nginx/access.log"]

[metrics]
interval_secs = 30

[shipper]
endpoint = "https://your-backend.com/ingest"
ship_interval_seconds = 60

Drop it in the same directory as the binary, or pass --config /path/to/uplog.toml

What gets shipped

{
  "agent_id": "prod-api-01",
  "timestamp": "2025-06-07T10:00:00Z",
  "metrics": {
    "collected_at": "2025-06-07T09:59:30Z",
    "cpu_usage_percent": 12.4,
    "memory_used_mb": 1024,
    "memory_total_mb": 8192,
    "disk_used_gb": 45.2,
    "disk_total_gb": 200.0,
    "network_bytes_sent": 104857600,
    "network_bytes_recv": 52428800
  },
  "logs": [
    {
      "source": "file:/var/log/app.log",
      "timestamp": "2025-06-07T10:00:00Z",
      "message": "GET /api/health 200 14ms"
    }
  ]
}

Every payload is self-describing. No schema registration. No agents to configure on the receiving end.
