Loki Logs Primer

Ship structured logs from Meridian into Grafana Loki for real-time tailing, label-based filtering, and long-term retention without the cost of a full Elastic stack.

Quick Start

POST /loki/api/v1/push
Content-Type: application/json

{
  "streams": [{
    "stream": { "app": "meridian", "level": "info" },
    "values": [
      ["1782585523243000000", "User login OK"]
    ]
  }]
}

Meridian's agent writes JSON lines to a local buffer, batches every 2 seconds, and pushes to your Loki instance over HTTPS. Labels are kept low-cardinality — app, level, and host only.
