aix performance monitoring tools

Yesterday, we had to spend half a day worrying about whether the system performance meets the requirements of a certain function. Because of the lack of relevant performance data, we had to stop it. Today, we searched for the was thread monitoring method to collect relevant performance data. PS-U was-O thread, where t

space is insufficient, the system response speed slows down or even suspends. The size of the swap area depends on the system memory size and the memory requirements of applications. The swap zone can be dynamically added on AIX, or the lsps command can be used to view the usage of the SWAp zone, and the vmstat can be used to monitor system memory page swap operations. Usually, the size of the swap area must be greater than the actual memory of the

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/

Efficiency is a key issue, but it is also a tricky issue. Inefficiencies can affect the user's experience, but many IT operations are not willing to take the effort to improve efficiency, because they still work. Especially after a few years of use of the system, mostly considered to be too much content, and so on.To help operators better monitor the efficiency of SharePoint, there are a number of tools built into SharePoint that allow operators to di
