Simply described, server monitoring is the systematic tracking, measurement, or observation of server activities and operations. To make these processes easier, a server management service can be used. The purpose of this is to improve the obtained data about the health and status of the server and ensure that it performs at its best.
Previously, deploying new servers required significant investment in data centers, hardware, and the creation of extra technical support and administration skills. IT businesses may access extra servers to perform a range of needs with low expense in today’s increasingly cloud-focused enterprise computing ecosystem. Infrastructure-as-a-Service (IaaS) services are provided by cloud service providers such as Amazon Web Service (AWS), Google Cloud, and Microsoft Azure on a pay-per-use basis, allowing businesses to scale their networking, storage, servers, and virtualization capabilities in the most cost-effective way possible.
As more servers are moved to the cloud, security may become a greater problem. Each extra network endpoint or cloud-deployed application is a possible attack vector for a hostile actor to get network access. Maintaining the speed and availability of servers, as well as their security posture, may help to improve the customer experience and reduce unplanned downtime.
Because of these issues, businesses that rely on cloud-based servers must employ server monitoring solutions that assist keep cloud servers secure while also measuring their performance and availability. Depending on the kind of server, server monitoring can have different aims and track different key performance indicators (KPIs), but the fundamental goal of server monitoring is to safeguard the server from probable failures that would disrupt service availability.
A server monitor ensures the performance and functioning of various servers (web servers, app servers, email servers) and provides a number of advantages, including:
- Website monitoring aids in the real-time evaluation of servers: Website monitoring solutions allow you to examine the health and performance of your servers in real-time by keeping track of critical parameters that are important for a well-functioning infrastructure. In this manner, you can always do the required maintenance to keep everything running well.
- Website monitoring software aids in the detection of bottlenecks: A measure that is out of range is a sign that there is a problem. A good server monitoring system aids in the detection of bottlenecks so that they may be addressed before they worsen.
- Website monitoring helps to create an error-free, automated environment: By automating operations and performing inspections on its own, a trustworthy server monitoring system will take on time-consuming chores. Its added degree of automation eliminates the need for system administrators to manually verify log files, lowering the chance of human mistakes.
- Website monitoring aids security management: Whether we’re talking about a web server or another form of server, infrastructure monitoring is critical to security orchestration. IT managers have a better grasp of a company’s security posture when they use a security tool.
- Website monitoring software optimizes resources: A high level of automation equates to efficiency. People may focus on the jobs where they make a difference rather than collecting and analyzing data since resources are used better and more efficiently.
- Stakeholders are kept pleased with a decent server monitoring tool: Because it provides a pleasant end-user experience, a working server makes staff and consumers pleased.
A virtual server (VS) is separate from the hardware, unlike a traditional server, which is usually a real machine running an operating system and one or more server applications. A virtual server is a shared software environment that mimics the operations of a physical server. When administrators realized that their companies weren’t getting the most out of their hardware servers, they became popular. If a corporation only uses 20% of its capacity, for example, it might be wasting money on processing power that it doesn’t require.
Physical servers require considerable management, maintenance, security checks, and other services, all of which are costly. As a result, firms aiming to save costs and increase ROI may consider migrating their servers to a virtual environment.
Virtual servers are often obtained from specialized suppliers. These companies run infrastructures that are made up of hundreds upon thousands of physical servers located in data centers all around the world. Using cutting-edge web-based interfaces, businesses can rent and operate servers entirely online.
Administrators may also easily set up and manage their virtual servers. This enables them to scale up in response to a sudden surge in activity and then scale down afterward. Virtualization companies only charge for the amount of power used, thus employing virtual servers instead of actual servers may save you a lot of money.
Multiple virtual servers, often running as virtual machines (VMs), can share the underlying hardware by abstracting from the hardware layer. Hardware resources may be dimensioned according to each VM’s needs, allowing them to be used more efficiently. This is frequently accomplished through the use of a hypervisor, which distributes hardware resources such as CPU utilization, disk usage/space, RAM, and hard drive space across virtual machines.
Website monitoring is a wide word that refers to a server’s overall health, whereas server performance monitoring focuses solely on performance data. Memory and CPU usage, as well as disk I/O and network throughput, are the most important indicators for a physical server. Depending on the kind of virtual server, performance metrics may include database or web server response time, network bandwidth use, and other indicators of resource utilization.
Website monitoring performance is crucial for a variety of reasons. For starters, it is frequently predictive – slowdowns and other performance concerns may be informative in assisting IT in identifying impending problems. Capacity management tools may be used to predict what resources will be required to support a new application or other workloads, and bottlenecks can be valuable in identifying where component or service improvements are required.
Another important factor to consider while measuring server performance is compliance. Many businesses pledge to deliver a specific degree of uptime or performance, which is crucial in high-stress areas like financial trading, SaaS solutions, and streaming media. Compliance fines might be harsh if performance falls below specific standards.
Open-source monitoring is a monitoring solution based on open-source software, which frequently incorporates additional open-source tools or the usage of Linux.
When it comes to monitoring IT infrastructure, however, these solutions aren’t only for Linux servers; they can generally monitor all major operating systems.
Users may also inspect, modify, and distribute the underlying code using open-source software.
Open-source software is crucial to the monitoring system in an open-source monitoring configuration. It usually uses Linux and other open-source solutions, and it keeps track of IT and server infrastructure (for Linux or proprietary servers).
Open-source software refers to programs whose code may be accessed, modified, and distributed by anyone. Although open-source tools may function as well as commercial ones, many users prefer the latter since they are typically easier to install and use. Commercial server monitoring technologies (often cloud-based) are usually turnkey, making them easier to use and providing a better user experience.
While server management software comes in a variety of flavors, each one focuses on a particular aspect of monitoring. We’ll go through 4 of the top server monitoring tools and their unique features in this part.

On the market, there are a plethora of server performance monitoring tools, both open-source and SaaS. They all get the work done at the end of the day. Choosing the proper one is a function of your organization’s needs as well as the resources (effort and money) available. When selecting an enterprise monitoring system, keep the following points in mind:
All of the metrics that are essential to you should be collected and analyzed by your monitoring system. Some technologies provide a small number of measures, while others support a big number of metrics that you don’t require. You must also be able to set and adapt the metrics you do need to meet your needs.
While DIY tools may appear to be thrilling and entertaining, they may be irritating when things don’t go as planned. You should search for an enterprise monitoring system that is simple to set up, takes little maintenance, and has most of your needs covered by default settings for alerts and dashboards.
Even if a tool provides all of the metrics you want, it is inconvenient if there is no correlation between them, which is especially true when troubleshooting an issue. Proper metric correlation may save you a lot of time and allow you to dig down to the main cause of your problem in minutes.
It is not always possible to set a fixed threshold for a certain measure to trigger an alert. You might not even realize you need an alert until something goes wrong. Most alerts will be automated and configured for you using tools that have anomaly detection capabilities and are connected with machine learning and artificial intelligence.
