Hi Teams, I just started using SigNoz and have been assigned a task to create a dashboard displaying Apdex information, similar to the Apdex in the SigNoz service. From what I found in the community, there is a suggestion to use the formula: APDEX_DELTA_SPAN_METRICS = '(B + C/2)/A' where A - total requests, B - requests with duration < threshold, C - requests with duration < 4 * threshold. However, I'm not sure how to retrieve the data for A, B, and C. Could someone help me with this? And I am using the Query Builder to create the dashboard, and the Panel Type is set to Time series.

You can check this dashboard: https://github.com/SigNoz/dashboards/blob/main/apm/apm-metrics.json And follow docs here on how you can use custom APM metrics: https://signoz.io/docs/userguide/custom-apm-dashboards-alerts/
