372 47 90 10 0 0From the first result above, we can see that the last column (ID) represents the idle time. We can see that during baseline statistics, the CPU idle time is between 79% and 100%. the second result shows that the system is in the 100% usage and there is no idle time. from this comparison, we can determine whether the CPU usage should be optimized.2.0 install monitoring toolsMost * nix systems have a bunch of standard

replica for each secondary replica, the contents of which are logs buffered from the log or capture from the disk, and the size of the queue reflects the difference between the primary replica and the secondary replica data being out of sync.Obviously, the two key factors that are most likely to affect AlwaysOn synchronization performance at this stage are the source of the capture log (disk or memory) and the size of the queue.In both of these facto
Monitoring is the core task of cluster management. Monitoring data can be used for scheduling tasks, load balancing, reporting software and hardware faults to administrators, and extensively controlling system usage. The monitoring information must be obtained without affecting the cluster performance. This article wil
