Monitor span count to understand operation volume Examples: 1. Get details for an API endpoint span group json { "spanGroupId": "[HttpClient]GET-api.example.com" } Expected Output: Statistics, category, and performance target info 2. Get span group details with device filtering json { "spanGroupId": "[HttpClient]GET-api.example.com", "filters": { "device.browser_name": [ { "type": "eq", "value": "Chrome" } ] } } Expected Output: Statistics filtered for Chrome browser only Hints: 1. Use List Span Groups first to discover available span group IDs 2. IDs are automatically URL-encoded - provide the raw ID 3. Statistics include p50, p75, p90, p95, p99 percentiles.
