There are many monitoring systems on the market, each with its own characteristics and capabilities. The best monitoring system for your company will vary depending on your specific needs and budget.

Some of the leading monitoring systems include:

• Nagios: One of the most popular open-source monitoring systems available. It lets you monitor the availability of services and devices, and it provides customizable alerts and reports.
• Zabbix: Another open-source monitoring system that offers advanced monitoring features, including performance monitoring, automated problem detection, and integration with other management tools.
• PRTG Network Monitor: A commercial network monitoring system that monitors network devices, services, and performance, along with customizable alerts and reports.

However, before you focus on the monitoring system itself, it's important to assess the maturity of your IT service management processes. A monitoring system alone isn't enough to ensure the stability and security of your network. You need event, incident, change, and problem management processes in place to make sure issues are identified and resolved quickly.

Event management is the process of identifying, classifying, prioritizing, and resolving problems and incidents in your IT environment. Incident management is the process of handling those incidents, including communicating with the business and support teams, identifying root cause, and implementing solutions to resolve the problem. Change management is the process of managing changes to the IT infrastructure, including communicating, approving, and implementing those changes. Problem management is the process of identifying and resolving chronic problems in the IT infrastructure.

It's important to have a dedicated team and clear processes to handle these incidents, changes, and problems. Infraops is a company that specializes in this area and can help you implement these processes and keep your IT network stable and secure. We have a team that specializes in Zabbix and PRTG for a correct and secure deployment.
