Then it is now determined that the problem is caused by IO. Grafana Monitoring Node Exporter - Disk can help us locate specific locations. However, in this case, the disk IO Util has risen somewhat during this time but has not reached the bottleneck, but most of them still maintained below 40%. IOPS and Disk Throughput have not changed abnormally. Compared to other time periods, the overall disk load is normal.

More than 60% are generally bottlenecks
