CPU at 5%

[arnaud-secondlayer]

I've started using Milvus on Google Compute Engine. The version is 2.4.1.
The database has been provisioned a day ago and there is no connection to the database yet.

The instance CPU stays at around 5% and I can see a constant stream of logs.
Is this behavior expected, or is there something wrong with my setup?

To collect metrics for monitoring system, the describeIndex() interface of datacoord is called by the querycoord for every 1 ~ 2 seconds. Not a problem.

[xiaofan-luan]

don't think this valid @xiaocai2333
why not report this metrics directly from index coord?

[xiaocai2333]

It is reported directly from datacoord, but the log is printed more frequently. The log has been reduced in the latest version.
