Linux server monitoring

It is the job of the admins to determine the cause of the Linux server’s reduced speed. There could be several potential causes for it. Could be a hardware issue, or the culprit could be an application malfunctioning in your server. It could also be caused by the stress of having to handle the workload that is larger than the server is prepped to carry. Maybe there is a bottleneck, however, where the bottleneck exists is the question. Network, memory, CPU or disk?

In order to carry out Linux server monitoring efficiently, every step of the server needs to be accessed and assessed by the admins. They need to see several performances of different layers to figure out the part of your server that is bottlenecked.

  1. Memory

Monitoring memory is one of the most crucial aspects of understanding what has brought your system to a halt. It could be for memory overflow or a modified application. It allows you to spot the servers that are being used too much, or not enough. This will help you delegate the load evenly, which could help prevent server downtime or loss of data from taking place.

Even though the physical memory of a system has no more space when more is needed, a swap memory, which is virtual memory, is made by the system to use in place of the disk space. If your swap memory is being used a lot, it could be an indicator that there is no more memory left in your Linux server.

  • Organised your Linux servers

In order to ensure that all your networks and servers are organised, you need to build your infrastructure in such a way that all the categories can be accessed and seen properly. You can accomplish this by grouping servers according to their business function and showing their status to your users as “traffic lights”. When you acquaint yourself with the health of your server, it becomes manageable to utilise functional, rational maps that provide fast understanding and navigation of your entire network configuration and its workings.

  • Load

The amount of CPU utilisation can be understood from the indicated load, asking with the amount of execution and the time frame that it has been utilised for. Basically, it sheds light on your performance’s computation load. Load average also lets you know the effects on the system of running threats which is highlighted by the average asking of traffic, both waiting and running.

The load metric puts into the spotlight the sheer amount of instructions that are looking for done CPU time and moreover CPU demand. The calculation of average load is done in a period of 15, 5, or 1 minute. The complete CPU cooling on the system and the load average should come up equal.

  • Prioritize your Linux server monitoring commands

Linux commands are the most efficient way to become the most coveted Linux sysadmin along with gaining a complete oversight of all Linux servers. While you can gain the informatics that shell commands provide through the use of GUI programs, Linux GUIs are known to utilise resources that are important enough to be better employed for a different task. 

  • Inode Usage

A Linux server is filled with files. You require an efficient tool that stores the block location of your data’s disk, as well as its features. Inode numbers are utilised by a Linux system in place of filenames to help them segregate the directories and identify them when they are being made. Metadata and data form these directories.

Inode allows you to store all of the metadata of your file including user ID, for location, timestamps, size, for access allowances, device ID, etc. Since inode is part of all files, you can use the disk’s inodes before you run out of space on your disk.

An efficient Linux monitoring tool can help you track the characteristics of your inode and provide a succinct understanding of the number of nodes you have consumed, as well as the amount of space that is left. You can receive alerts when the utilisation of inodes can go above a given limit so that you can take precautions and measures to avoid any performance issues your server might encounter. Getting rid of unused files can help decrease inode utilisation.

  • Safeguard your Linux environment with security measures

Linux servers monitoring is one of the crucial ways to keep your IT infrastructure secure from any threats to its security. A monitoring solution can be implemented to keep a track of any word that might occur in your system, of any breaches or threats it might encounter from apps that do not have permission. Getting to know these threats in advance can help you deal with them rapidly and ensure that your entire system is kept safe. You might want to invest time in firewall building and keep a track of new additions to your system. 

Conclusion

The security measures mentioned above can help you keep your system safe and secure as time goes by and help boost your monitoring. Linux server monitoring can be easily done if you employ all the measures mentioned above.
