Linux is an open source operating system that is quite popular. One of its advantages is that it has a relatively stable server. However, you still need to pay attention to Linux server performance.
Monitoring Linux servers aims to observe the performance of the operating system. That way you can find out whether or not there are any disruptions. In addition, it is also to ensure that services or businesses run smoothly.
Why is Paying Attention to Linux Servers So Important?
For Windows operating system users, the term CMD, or Command Prompt, must be familiar. CMD itself has a number of command line lists that can be used, one of which can be used to check the internet network.
Just like Windows, Linux also has a number of commands like CMD that can be used to check its performance. Paying attention to server performance is very important, because this component is the backbone of IT infrastructure.
For example, when there is a spike in memory or CPU that can affect its performance. When its performance is disrupted, the website or application will also be disrupted. The bad effect of this is that it can have a negative effect on the business or services you have. So, it is important to always do server monitoring.
How to Check Linux Server Performance?
Checks can be done to ensure the performance of the Linux server and also the operation of applications that depend on the server. Here are some ways you can do to check.
- Pay attention to CPU Usage
The first thing you should pay attention to in the Linux server performance test is CPU usage. This element will show signs of slowing down. By monitoring it regularly, you can analyze the CPU load.
The CPU on the Linux server will be calculated using the “vmstat” command. This utility command provides information about CPU activity.
- Check System Load
The next monitoring that you should pay attention to is the system load. System load is one of the metrics that you can use to monitor the Linux server.
System load displays a list of metrics that need to be checked and represents the average number of instructions while waiting for CPU time and the overall demand on the CPU. The average system load must be the same as the total number of CPUs in a system.
- Memory Usage
Next, identify servers that are overused and underused in redistributing the load. Calculate memory usage that can be checked with the “Free” command. - Disk Utilization
Next, monitor the Linux server disk through disk utilization. This method will help you minimize the risk of hardware failure.
You can gain insight into disk writing and disk reading. Through disk utilization, there are many processes that have been written and read from the disk when the process starts.
- Check Inode Usage
On a Linux server, everything is a file. The system itself generally uses an inode to identify files when they are being created. The system itself is divided into two parts, namely actual data and metadata.
All this inode data will be stored in one table. With the inode number, you can easily calculate the offset in the table. The reason is, each file has an inode.
How to Improve Linux Server Performance
There are several powerful ways to optimize a Linux server. One of them is optimizing the performance of swap space which is part of the hard disk.
In addition, it can also be done through the hardware section, for example, such as the CPU which affects the quality of the Linux server. But don’t worry because now there is an easy solution for monitoring Linux server performance, namely using Netmonk Prime from Netmonk. A monitoring dashboard that provides convenience in monitoring servers, especially Linux, whose services are ready to help maintain optimal server quality. Try the free trial for 14 days now!
