For example, … WebYou can use Prometheus and Grafana to visualize the metrics. This topic introduces the monitoring metrics displayed in the Grafana Milvus Dashboard. The time unit in this topic is milliseconds. And "99th percentile" in this topic refers to the fact that 99 percent of the time statistics are controlled within a certain value.
WebJan 29, 2024 · increase (): This function is exactly equivalent to rate () except that it does not convert the final unit to "per-second" ( 1/s ). Instead, the final output unit is per-provided-time-window. Example: increase (http_requests_total [5m]) yields the total increase in handled HTTP requests over a 5-minute window (unit: 1 / 5m ).
