Network Olympus Server Monitoring

Server state monitoring

Computers do not always perform at their best performance, especially in a large company. A reason for this can be excessive load on the server. In order to avoid slowdowns in the work of the server, it is necessary to monitor its state and analyze the change in load in real time.

What is server load and why should you monitor it?

Server load is the percentage of server resources consumed in a period while a task is running. To complete some tasks, 1-2% of the total number of resources will be sufficient, other tasks can be more complicated and 80% of the resources should be spent on their computing. Thus, it is necessary to monitor the state of the server to understand what exactly "loads" the system.

The server load analysis involves processing the statistics of operation of each main element that makes up the server:

  • CPU - the workload should not exceed 20%, only special-purpose servers can be an exception;
  • memory - if there is not much free memory left, you should think about purchasing additional RAM or several servers, amidst which you can allocate the load;
  • drives - free disk space must be at least 10%. When analyzing HDDs and SSDs, pay attention to the total amount of data that is being read from and written to the disk;
  • network interface - network traffic can be high, but if your bandwidth is limited to 100Mbps and your system averages 90Mbps, you should consider adding new servers to balance the load.

If you do not monitor the load on the server, the acceptable threshold can be exceeded and the entire system will be idle until the cause of the failure is found and the problems are fixed. Downtime is expensive, so the best way to prevent potential problems and keep your server productive is to monitor its health.

Server load analysis methods

There are several options for diagnosing the server load in a shared hosting:

  • analysis of log files - helps you determine which pages are most accessed. You have to do this manually. To understand what changes are taking place, it is enough to compare the sections of the logs with normal and maximum load;
  • code audit - carried out to identify weaknesses in the code. Some portions of code may simply waste resources. After the ineffective areas are found, it is necessary to eliminate and improve them;
  • profiling - examining the implementation time of small chunks of code. Profiling allows you to find out which parts of the script need to be optimized in the first place.

How to reduce the load on a server

If you want to reduce the load on your server, firstly you need to determine which points are causing the most load. After that, you can start optimizing. Analyze the plugins and widgets that are in use. Quite often, some of them can waste the CPU. If a lot of resources are spent on page generation, you need to think about page caching.

There are many ways to reduce the load on the server, but if you do everything manually, it will be a very time-consuming and difficult task. In order to automate the processes on your network, it is better to choose special tools for server monitoring. These can be paid or freeware programs that are suitable for creating and managing monitoring scenarios.

Software for monitoring the load on a server

An optimal solution for monitoring the load on a server should generate reports and graphs based on the following indicators:

  • CPU load;
  • network traffic;
  • amount of free disk space;
  • running processes;
  • consumption of memory used, etc.

If deviations from normal values are detected, the application should report the problems and suggest taking actions aimed at correcting the malfunction. You can easily track and find out the reason of the increased load, because special software keeps logs of each monitoring event.

Our Network Olympus program is a great product for monitoring workloads and automating tasks related to collecting information, resolving problems and reporting them when they occur. The full functionality of Network Olympus can be tested for 60 days. If you monitor less than 10 devices, then you can use the free license with no time limit.
