Recipe: Grafana dashboard JSON writer

Overview

Meridian exports structured telemetry that maps directly to Grafana's dashboard model. This recipe walks through constructing a valid dashboard JSON with panels, templating variables, and time-series queries wired to your Meridian data source.

Prerequisites

• Meridian agent running with telemetry export enabled
• Grafana 10.x or later
• JSON-aware editor (VS Code, vim, or similar)

Step 1 — Dashboard skeleton

Start with a minimal dashboard object containing uid, title, and empty panels array. Set schemaVersion to 39.

Step 2 — Add time-series panels

For each Meridian metric (CPU, memory, injection latency), create a panel with type: "timeseries". Wire the targets array to your Meridian-compatible data source UID.

Step 3 — Templating variables

Define a templating.list entry for hostname so operators can filter across machines without editing panel queries.

Step 4 — Validate and import

Paste the completed JSON into Grafana's “Import dashboard” screen. Verify all panels render and variables resolve before saving.
