Preventing failures: The basis of IT infrastructure monitoring












The main purpose of IT infrastructure monitoring is to prevent potential problems or failures. However, should an error occur, IT monitoring software lets you quickly identify and troubleshoot the issue. The goal of IT infrastructure monitoring is to provide for uninterrupted availability and a functional and reliable IT infrastructure.

IT administrators use automated monitoring tools to monitor their infrastructures. In general, these tools work as follows:

  1. As soon as a threshold value (configured beforehand for the respective IT system) is exceeded, the IT teams are notified by the IT monitoring tool.
  2. The IT teams can then step in and fix the issue. IT infrastructure monitoring tools make it quick and easy to get to the root of (and eliminate) problems.

Server monitoring and management are
critical to your business


Servers (such as web servers, file servers, and mail  and database servers) play a vital role in any IT environment. As devices that provide resources via a network, the availability of servers is critical to any business. Server failures always have far-reaching consequences.

Unavailable systems lead to costly interruptions to business operations and losses of revenue. A common example: the server that hosts the software for an online store goes down. Data recovery can also be expensive when business data is lost and must be restored. Other consequences may include a loss of trust in the company and damage to its reputation.

An IT infrastructure monitoring tool lets you keep a constant eye on the things that might cause a server to crash:

  • Power outages
  • Connection problems
  • Update and backup errors
  • Overloading and overheating

PRTG is compatible with all major vendors & manufacturers

The monitoring of today’s IT infrastructures is automated – for good reason: an IT infrastructure must be available at all times to ensure all the processes at a company always run smoothly. This is the only way to keep business operations reliable, create a positive customer experience, and increase employee productivity.










Monitoring large IT infrastructures: Mission impossible?

IT landscapes at companies can be incredibly complex: usually, the networks of several locations must be monitored simultaneously. These networks often consist of devices from a variety of different manufacturers. This can make IT infrastructure monitoring extremely difficult. Among other things, a good IT infrastructure monitoring tool has the following characteristics:

The tool is user-friendly

The tool is user-friendly

An intuitive interface is important for ensuring that the monitoring is properly set up (with the relevant parameters) and executed. A user-friendly monitoring tool also sends automated alerts by email, SMS, push notification, etc. If the measured values deviate from the desired values, then IT administrators must be able to react quickly.

The tool grows with the IT environment

The right IT infrastructure monitoring tool will be compatible with heterogeneous IT infrastructures, as well as scalable. This means it will be able to seamlessly integrate additional (even vendor-specific) devices into the monitoring environment.

The tool allows for remote monitoring
