There are some charts in Grafana-Dashboard that have no data for prometheus metrics

[welyss]

For example the chart "Slow Query" in Service Quality:
increase(milvus_proxy_slow_query_count{app_kubernetes_io_instance=~"$instance", app_kubernetes_io_name="$app_name", namespace="$namespace"}[1m])
there is no milvus_proxy_slow_query_count metric in prometheus, my targets of prometheus include 6 pod monitor and 1 servicemonitor, am i missing some monitor setup?

All available metrics are listed here: https://milvus.io/docs/metrics_dashboard.md#Milvus-Metrics-Dashboard
I didn't see milvus_proxy_slow_query_count in this list, where did you see it?

@welyss Only when a slow search/query is recorded, the metrics will show up.
