From: http://bbs.51testing.com/thread-2196-1-1.html Hello everyone. In the future, we will discuss the design and design of LR monitoring performance counters and LR scenarios. Today, I will first paste out some counters and their threshold requirements. These counters are aimed at My

write cache exists and the algorithm is normal, RAID5 is even better than raid10, although there may not be much difference (here we should assume that there is a certain size of storage, enough write cache, and there is no bottleneck in the CPU for computing and verification ). This is because the raid check is completed in the cache. For example, for RAID 5 of four disks, you can calculate the check in the memory and write three data and one verification at the same time. Raid10 can only wr

: the average time required to write data to this disk in seconds. Network Interface: Bytes total/sec: the speed at which bytes are sent and received, including frame characters. Determine whether the network connection speed is a bottleneck. You can use the counter value to compare with the current network bandwidth.
