Monitor your system: FAQ


1. What is system monitoring?

System monitoring continuously observes and analyzes an IT system’s performance, health, and security. It tracks metrics and events in real time to make sure the system operates efficiently, securely, and within its expected parameters. It includes the monitoring of hardware like routers and switches, hardware parameters such as CPU usage and server memory,  network traffic, bandwidth, as well as the performance and availability of applications.

2. What is a monitoring system?

A monitoring system is software that helps sysadmins monitor systems in an IT environment. Monitoring systems come in many degrees of functionality and range from tools that do one thing really well to enterprise-grade solutions with the ability to monitor thousands of devices and applications.

3. How does system monitoring work?

The monitoring system tool communicates with your IT environment via SNMP, WMI, SSH, HTTP, and other protocols. Which protocol is used depends on the tool you choose, your application providers, and the device manufacturer (Cisco, HPE, Dell, etc.). 

4. Do I need a system monitoring tool?

Some IT managers adopt a reactive approach and only step in when there’s an issue. This is a risky approach and can lead to lengthy troubleshooting sessions. Other IT managers use a lot of small tools to oversee their infrastructure. Yet, these managers miss out on a unified dashboard that gives you an overview of your entire IT infrastructure. Implementing a monitoring system saves time, reduces stress, and cuts costs.

5. What are the advantages of a monitoring system?

Unlike smaller tools that may or may not communicate with each other, a monitoring system lets you see your entire network from a single computer and a central dashboard. You get immediate notifications when an error occurs so you can fix it quickly. Long-term monitoring also provides the data you need for predictive maintenance and accurate resource planning.

6. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
