Why do you Need Server Hardware Monitoring?
Servers are the backbone of any modern-day enterprise, and without them there would be no business to speak of.
Your servers work hard, ensuring that your applications, network connections and files are always available 24/7.
To make sure that your server infrastructure is always available we need to look at some of these important aspects of your server installations:
- Health monitors that give real time feedback regarding issues such as CPU temperate, CPU load, and other vital information about the wellbeing of your servers.
- Notifications and alerts. When an issue is detected, how do you find out about it?
- Finding out about what is needed and where for future upgrades
- Proactive software that minimizes system outages and down time
Here’s the Best Hardware & Server Monitoring Tools of 2021:
The SolarWinds Systems Management Bundle consists of four specialized tools that work together to give you a better idea of the current state of your server hardware and applications.
Each tool contains its own set of health and status monitors for multiple vendors and manufacturers.
Each tool also has hundreds of monitors for some of the most common applications such as SQL server, VMWare, Active Directory, Office 365 and many more of the apps that organizations need to get work done.
Server and Application Monitor
With this software you have the ability to both monitor your hardware and track your assets. It has the ability to monitor the CPU and memory usage of your servers, as well as other important metrics such as hard drive space, network utilization and a host of other important metrics.
If you have virtual assets in your environment then you can also use these tools to monitor key stats from your VMWare and Hyper-V hosts, as well as all of the virtual machines that are associated with them.
To help you get started you can select one of the over 1200 monitoring templates while you fine tune your own.
The virtualization manager tool allows you to deep dive into the monitoring and performance of your virtual environments, as well as the capacity planning and optimization plans for it.
These environments include support for VMware, Hyper-V and even Nutanix. One of the best features of this particular application is the ability to monitor virtual hard disks and receive alerts when there are breaches in your thresholds. It helps with maintaining diskspace as well.
Storage Resource Monitor
The Storage Resource Monitor is another great feature that allows you to view and access the performance and capacity of your storage devices.
It gives you a centralized location from where you can view and monitor storage related issues and devices.
It is compatible with most devices such as SANs, NAS types, and vendor support for HP, DELL EMC, NetApp, Pure Storage and many more.
Web Performance Monitor

Site24x7 is a cloud-based system monitoring tool that has modules to monitor networks, servers, and applications. It is particularly focused on tracing the application dependencies that lie behind all user facing software. This drill down to the resources of the server that hosts all of the supporting services and applications. A network monitoring module in the Infrastructure package enables you to check on the performance of network devices and track traffic volumes over the network.
As a cloud-based system, Site24x7 includes all of the processing and storage resources needed to run the monitoring software in with the price of the service’s subscription. However, it is necessary to install a data collection program on the monitored system. This collects statistics about the network, servers, and applications and uploads them over an encrypted connection to the Site24x7 server for processing.
The console for the monitoring system is accessed through any standard Web browser from anywhere. The screens in the dashboard can be customized by the user through a drag-and-drop facility.
Site24x7 Infrastructure places performance thresholds on all of the metrics that it measures. If the performance of any resource drops below an acceptable level, the system raises an alert. This is forwarded to technicians by SMS, email, voice call or instant messaging post.
Site24x7 Infrastructure costs $9 per month when paid annually.

Hardware Monitoring in an Enterprise Environment
We have put together a list of capabilities that are useful for monitoring infrastructure and server hardware in an enterprise environment. In most enterprise operations it is utterly essential to monitor and watch how the hardware, software, databases, virtual machines, websites, and much more, are operating. You need to have critical alerts that warn you when there are outages, reports to gauge overall performance, and other visibility enabling features.
If you are looking to get your own monitoring solution set up then you should strongly consider some of the following features as being part of your next setup.
1. CPU Utilization Monitoring
Your production servers need to be watched at all times, especially during peak times for your business.
For the most part you can rely on a Windows or Linux server to perform nominally, but the sad reality is that there are times when a rogue process or application can hog too much of the CPU’s valuable processor time.
Your next monitoring solution should have the ability to warn you when your processor breaches a predefined threshold.
2. Memory Utilization
Memory usage is just as important as CPU usage.
In a monitoring application you must have the ability to look at not only the available memory on each individual server, but also the memory usage of your virtual machines. Just as important is the virtual hosts in your virtual environment.
Memory usage is critical to supplying virtual servers, so being aware of the current state of memory allocation is very important.
3. Storage and Disk Monitoring
Your company data is important to keeping operations running, and when you run out of disk space, you run into a multitude of serious issues. Not only are you unable to save and update your work, but applications and programs will soon stop working too.
A modern computer system relies heavily on hard drive space, and when you run low, or run out, then your system is likely to fail.
Your monitoring solution must be able to alert you when specific hard disks run low or run out of space.
Once you have been alerted you can take action and get to work right away by clearing old backups, log files and user files that are taking up critical and valuable space on your servers’ hard drives.
4. Monitor Bandwidth utilization
Your company relies on the availability of bandwidth to communicate with the rest of the world.
If your internet is being hijacked by rogue applications on your network, or abused by disgruntled employees, then you need to be able to find out what is using it.
Most modern bandwidth utilization applications can tell you which applications are using the internet, which ports are open and using data, which network interfaces are most active, and which IPs on your network are using the most resources.
5. Historical Performance Logs
Historical Performance Logs help you to paint a picture and a timeline of events during an investigation.
User computers and servers both store a multitude of logs that reveal important information about the current state of the machine by investigating the log files leading up to the current issue.
Some of these applications can compile the information found in these historical log files and generate graphs and other visualization tools.
6. Alerts and Notifications
Dashboards are great, as are real-time graphs, but there is more to life than just staring at your monitoring screens. You need to be alerted to issues as soon as they are identified by your system.
The notifications can be emails, automated voice calls to your mobile phone, and even text messages.
The messages can contain information such as severity levels, fault descriptions, error information, and anything else that you would find important.
7. Customized dashboard
Your dashboard requirements will be different to the next person’s, depending on what you need to keep an eye on.
That is why it is great to have a monitoring solution that comes with prebuilt dashboards.
You can all have access to the same information right out of the gates, but then you can customize your own so that your specific issues can be detected very easily.
8. Monitor Services and Processes
You don’t want to monitor the current state of services and processes of every single computer and server on your network manually.
The time and effort that it would take for you to log onto each remote system would take up almost all of your time. You should have the ability to monitor all of the systems that need attention from a single source. This is a way more efficient way of monitoring your systems and ultimately leads to greater efficiencies.
9. Reporting and Inventory
When it comes time to forecast for your department’s budget, or when you need to show your manager how the resource planning and allocations are going it is important to have a proper reporting system.
You will need to create reports that are easy to read and informative without being too data intensive.
Executive summaries are very important for the upper management structures that need to be made aware of certain IT related issues..
10. Server Uptime and Availability
This is a very important feature, and it is arguably one of the most important features that any monitoring software suite could have.
Staying online and keeping the business running is your core mission, so choosing a piece of software that can help you to achieve this is the right way to go.
Each of the monitoring solutions that we have looked at have their own pros and cons. It is not easy to choose a winner, but it seems as thought the SolarWinds product ticks the most boxes for our hypothetical requirements.
We hope you have found this article useful and that you can now find the best application for your needs!
