What are the aspects of the performance of a CVM? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The performance observation of CVM includes several different aspects, such as CPU, memory, hard disk and so on. Application services need to use disk space for data storage and processing, so the server disk space should maintain a certain amount of free capacity.

CPU utilization

1. Server CPU utilization, which can be analyzed separately for each CPU of the system.

two。 CPU utilization and CPU usage time occupied by the server's current process list

3. Display server CPU performance (process display) real-time changes and historical trends

4. Server CPU threshold alarm, server process CPU occupation threshold alarm, when the occupation of CPU is too large / small to generate an alarm.

Memory utilization

1. Server memory utilization: the memory occupied by the current process list, memory utilization

two。 Display server memory utilization (process display) real-time changes and historical trends

3. Server memory utilization threshold, server process memory utilization threshold, and so on.

Performance analysis of hard disk

You can collect the disk performance status information of the CVM. Help users to analyze the busy degree of disk reading, because the disk Istroke O information is a common factor affecting system performance, and then get the reference index to optimize the performance of the whole system.

Traffic resource record

The network traffic of the server comes from the data exchange between the server and the outside world. This traffic includes data exchange between normal applications and the outside world, as well as data traffic generated by illegal services or processes, such as viruses. Regular analysis of the server network card traffic over a period of time, you can find whether there are abnormal changes, such as sudden increase or sudden low, which is very helpful to check the running status of the server.

The answers to the questions about the performance of the CVM are shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
