Read-only Grafana health/config check.

Read-only search of Grafana dashboards (by title substring and/or tags). Returns uid, title, folder, tags and url for each. Use the uid with grafana_get_dashboard to fetch the full dashboard JSON.

Read-only fetch of a Grafana dashboard's full JSON by uid (panels, variables, queries, meta). Get the uid from grafana_search_dashboards.

Read-only list of configured Grafana datasources. Returns uid, name, type and is_default. Use a datasource uid with grafana_query.

Read-only metric/log query via Grafana's /api/ds/query. Provide the datasource uid (from grafana_list_datasources), a raw expression (PromQL for Prometheus, LogQL for Loki, etc.), and an optional time range. By default returns a compact per-series digest (labels + count/first/last/min/max/avg); pass raw=true for the full (potentially very large) frames.

Read-only: build a permanent Grafana Explore (Loki) link for a customer's logs AND return a preview of the most recent lines. Identify the customer/component with free text (e.g. client='april', component='gateway') — it matches case-insensitively against the service_name label, which encodes both. Optionally narrow with line_filter (substring that must appear in the log line). Default range is the last 1 hour; widen with from/to (e.g. from='now-6h'). Returns { query, explore_url, range, preview_count, preview }. Paste explore_url into the ticket; ask the user before widening the range since logs are large.
