Is there an easy way to tell the unit of metrics?

Hi,

I am viewing milvus metrics from https://milvus.io/docs/metrics_dashboard.md. I am wondering about units for those latency metrics especially because they are not specified anywhere I can find. Besides, those latency metrics do not share the same unit. This increases the difficulties when explaining metrics.

For example, proxy_req_latency uses milliseconds, while indexnode_save_index_latency uses seconds and datacoord_task_execute_max_latency uses nanosecond.

The first paragraph of the doc https://milvus.io/docs/metrics_dashboard.md mentions "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."

@jubingc Most of the latency related metrics use milliseconds while index related metrics use seconds instead.
proxy_req_latency use milliseconds, datacoord_task_execute_latency use milliseconds, while indexnode_save_index_latency use seconds.

We'll add a column to describe the metric unit in the https://milvus.io/docs/metrics_dashboard.md.

Thank you for all of your responses.
