When it comes to IT systems, unexpected problems and events often have serious consequences. If a server fails, important data can be lost and employees may no longer have access to emails.

In the worst case scenario, the entire IT system can crash unless a prompt and adequate solution is found for the problem. Not surprisingly, such scenarios are extremely costly. It is therefore in a company’s best interest to invest in 24/7 monitoring for a good network management.


What is 24/7 monitoring?

IT monitoring involves continually verifying the functionality of the operations and processes in an IT environment.

24/7 monitoring is continuous, round-the-clock monitoring. Systems are not only monitored at specific times, but 24 hours a day, seven days a week.


Which values are measured during IT monitoring?


 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Most companies today possess a variety of different systems that need to be monitored constantly.

24/7 monitoring tools come equipped with sensors that measure the various elements of these systems.

Among other things, these sensors monitor:

  • Server services and programs
  • Functionality of the mail server (Exchange Server monitoring)
  • Data backups (i.e., whether all backups have been performed correctly)
  • Status of hard drives (capacity and read/write errors)
  • Processing capacity (bottlenecks are an indication of operating errors and/or malware)
  • Fan temperatures (to protect servers and desktop computers from overheating)
  • Internet connections (problems with VPN and WAN connections)
  • Validity of SSL certificates

What are the advantages of 24/7 monitoring?



Professional 24/7 monitoring tools offer companies numerous advantages.

Above all, they provide for round-the-clock monitoring, 365 days per year. As a result, they improve the availability and stability of IT systems.

24/7 monitoring tools come equipped with sensors that allow for prompt alerts in the event of malfunctions. They therefore let you detect and eliminate critical operating conditions immediately, before any real damage occurs.

What’s more, regular reports and analyses help you monitor the long-term development of your systems. Among other things, these reports allow you to quickly identify gradual drops in performance by way of corresponding KPIs.


What makes for a good 24/7 monitoring tool?

PRTG ist unabhängig


A professional 24/7 monitoring tool should come with a system that offers a variety of different means for sending alerts. For example:

  • An audio file (jingle)
  • A free push notification sent to a smartphone
  • A notification sent by email

Automated handling of malfunctions

The tool should also come equipped with a feature that provides for the automated handling of malfunctions. Response times are continually compared by multiple points of presence (PoPs) at different locations in the network, and in the event of a malfunction, can be taken over by another PoP.

The tool should also contain dashboards that make it possible to quickly and easily view the status of a network. In particular, it should offer customizable dashboard templates for this purpose. The tool should also allow for its data to be processed in other systems. A good 24/7 monitoring tool can export its data to files such as HTML, XML, CSV, and PDF.
