Description

The get_dashboard_panel_queries tool only returns panels that use Prometheus/Loki-style queries. Panels using other datasource types (CloudWatch, Elasticsearch, etc.) are silently omitted from the results.

Root Cause

In tools/dashboard.go around line 320, the query extraction only checks for the expr field:

expr, _ := target["expr"].(string)
if expr != "" {
    result = append(result, panelQuery{
        Title:      title,
        Query:      expr,
        Datasource: datasourceInfo,
    })
}

Since expr is specific to Prometheus/Loki targets, any panel using a different datasource type gets skipped. For example:

• CloudWatch targets use namespace, metricName, dimensions, statistic, region
• Elasticsearch targets use query, metrics, bucketAggs
• Other datasource types have their own query structures

Steps to Reproduce

1. Create a dashboard with a mix of Prometheus and CloudWatch panels
2. Call get_dashboard_panel_queries with the dashboard UID
3. Only Prometheus panels are returned; CloudWatch panels are missing

Expected Behavior

All panels should be returned regardless of datasource type, with a normalized or datasource-appropriate query representation.

Suggestion

The tool could:

1. Check for expr (Prometheus/Loki)
2. Fall back to other common query fields like query (Elasticsearch), or build a summary from structured fields (namespace/metricName for CloudWatch)
3. As a last resort, include the panel with a serialized representation of its targets so it's at least visible in the results rather than silently dropped
