System monitoring FAQ

What is system monitoring?


System monitoring involves the continuous monitoring of an infrastructure – aka an IT system – by an IT manager. It includes the monitoring of CPU, server memory, routers, switches, bandwidth, and applications, as well as the performance and availability of important network devices.

What is a monitoring system?


A monitoring system is software that helps system administrators monitor their infrastructure. These tools monitor system devices, traffic, and applications, and sound the alarm in the event of malfunctions and disruptions. There are lots of monitoring systems on the market, from freeware to professional software.

 

How does system monitoring work?

During system monitoring, devices and applications communicate with the monitoring system by way of protocols such as SNMP, WMI, HTTP, MQTT, and OPC UA. The device manufacturer (Cisco, HP/HPE, Dell, etc.), application providers, and monitoring tool determine which protocol is used.

Do I need a monitoring system?


Some IT managers only intervene when an error occurs. But this comes with a lot of risk. And troubleshooting can be extremely time-consuming. Other IT managers monitor their infrastructure with a variety of small tools. But unlike monitoring systems, these tools are unable to provide an overview. A monitoring system will save you time, worry, and money.

What are the advantages of a monitoring system?

A centralized monitoring system lets you monitor your entire network in real time from a single machine. If an error occurs, you’ll be notified immediately and can fix the problem at once. This saves you time and provides for peace of mind.

 “Hey Greg, what would you tell administrators looking to monitor their Windows Server with PRTG?“

„PerfCounter custom sensors are some of the most useful sensors to be overlooked by users. Imagine SNMP sensors, but for Windows performance counters. Simply find out the name of the counter you wish you monitor. There’s a great knowledge base article on this topic.

Once you have the name, setting up the sensor is a piece of cake. It’s amazing to think of how many PerfCounters are really available for Windows applications, especially those which don’t come from Microsoft itself. These counters often offer insights into applications or processes which you may have once thought to be impossible.“

Greg Campion is a SysAdmin at PAESSLER AG.

 

Monitoring system tools: Free or paid?   

Free monitoring system tools

Many sysadmins use the command line for certain inquiries such as whether or not a device is available. Many device manufacturers also offer their own monitoring tools, some of which are free of charge. However, unlike PRTG, neither of these solutions will provide you with an overview of your entire IT system. What’s more, with our network monitoring system, the first 100 sensors are free and never expire. You can also access the alarm and all other features for as long as you like. PRTG can therefore be used as free monitoring software.

Paid monitoring system tools

There are lots of paid monitoring tools on the market. Sysadmins often compare PRTG with monitoring software such as ManageEngine, Zabbix, Solarwinds, and WhatsUpGold. The open-source tool Nagios is yet another option. Many IT managers also look for alternatives to their existing tools and come across PRTG. See our handy comparison of the various network monitoring tools including the results of independent tests.

5 advantages of PRTG

All-in-one system monitoring

Most IT systems are years in the making. More often than not, they contain devices from several different manufacturers. A central network monitoring system provides you with an overview of your entire IT infrastructure. All information is consolidated on one main dashboard. A quick glance is all it takes to see if everything is OK.

Real-time traffic monitoring  

PRTG monitors network traffic in real time. Among other things, it displays the web traffic and mail traffic that flow through your network. If you notice an anomaly or a spike in traffic, you can take action at once.

Prompt alarm in the event of errors

In large IT systems, errors can crop up in countless different places. A single damaged switch can cause a major disruption. Network monitoring systems allow you to quickly identify errors and their sources, thereby speeding up the troubleshooting process.

Remote monitoring

Many companies have multiple branches in a building complex, a city, or a region. PRTG is agentless software. It comes with remote probes that are quick and easy to install and let you monitor distributed networks from one central location.

Free network monitoring 

PRTG comes with 100 free sensors that never expire. You can also use its full range of features for as long as you like. This is all you really need for basic network monitoring. What’s more, for the first 30 days you get access to an unlimited number of sensors so you can really put our software to the test. Afterwards, simply choose the license that corresponds to your needs.

 

PRTG is a vital tool for getting your IT into tip-top shape!

The costs for a one-year PRTG license pay for themselves in an average of only a few weeks.
License costs vary according to the size of your network.
