GCP Cloud SQL for MySQL网络吞吐量参数250/2000含义咨询：250为平均值、2000为可达最大值吗？

Hey there! Let me break down what the 250 of 2000 MB/s metric means for your Cloud SQL for MySQL instance:

• 2000 MB/s: This is absolutely the maximum achievable network throughput limit tied to your current instance configuration. The value is determined by your instance's machine type (like db-n1-standard, db-custom series, etc.)—each instance class comes with a predefined network bandwidth quota, and 2000 MB/s is the peak rate your instance can support under ideal conditions.

• 250 MB/s: This isn't an average value. Instead, it represents the real-time (or recent sampling period) network throughput your instance is actively using. By default, Cloud SQL's monitoring dashboard shows metrics sampled over a short window (e.g., 1 minute), so this number reflects the current rate of data being transmitted over the network, not a long-term average.

If you want to check the average throughput over a specific time frame, you can go to Cloud Monitoring, select the network throughput metric, and adjust the aggregation function to "Average" for your desired time range.
