Server Monitoring Software is an essential tool for system administrators, as it allows for automated reporting, scheduled checks and pre-emptive warnings about the health of your many servers within your operating environment.
Server Monitoring Software is able to check everything about your system, such as:
- CPU usage
- RAM utilization
- Hard Disk Space
- System Temperatures
- Server Alerts (Hardware status warnings)
- RAID Array health checks
- Virtual Machine Alerts
You can also monitor user logins, suspicious activity on your server, and the status of your services and daemons.
There are multiple layers of technology at work inside these software suites, and some of the most common protocols that we will be mentioning today are:
- SNMP (Simple Network Monitoring Protocol)
- WMI (Windows Management Instrumentation)
- ICMP (Ping)
- PerfMon (Microsoft Windows Performance Monitor)
Depending on the software that you use, there could be any number of the aforementioned protocols within the monitoring application, depending on what the application monitors, and what environment it runs in.
We will now take a brief look at 10 of the most popular tools that are currently available, including free, paid, and open source tools and software.
Each has its own approach to solving the problem of trying to help monitor your system, and as such, some will be more suited to specific tasks than to others.
This can be a little confusing, so we will do our best to help you to understand which program could work best for your needs.

This list is no means exhaustive, and there are many other great products out there that offer similar functionality to some of the applications that we have looked at today.
Reporting and monitoring is critical in business, especially when it comes to IT infrastructure such as network connectivity and server monitoring.
Being able to look back at historical trends and faults is especially useful when troubleshooting an issue on a critical server or service, so if you don’t already have a solution in place, then it might be time to seriously consider it.
