Data center humidity monitoring protect servers

Data center infrastructure management (DCIM) software is usually used to manage the operation of a data center. Since certain atmospheric conditions can cause servers to malfunction or become damaged, the server room should also be monitored for temperature and humidity. This monitoring is broken down into data center temperature monitoring and data center humidity monitoring.

Unfortunately, many companies focus solely on temperature monitoring and forget to monitor humidity. However, there are many reasons why server room humidity values should also be included in your monitoring environment.


What causes humidity to rise in data centers?

data center


Data centers and production facilities are subject to regular fluctuations in temperature and humidity. There are several factors that cause the relative humidity in a data center to rise. For one thing, moisture can accumulate due to insufficient or intentionally low ventilation. Evaporation of water and evaporation from materials can also occur. Even emissions from hardware, equipment, and machinery increase humidity.

Why is it important to protect data centers from humidity?

Systems and server racks in the server room are highly sensitive to environmental conditions. These rooms must therefore be monitored digitally to ensure their relative humidity always falls within an acceptable range.

The relative humidity in the server room is too low:

If the air is too dry, physical devices can become charged with static electricity. In the event of a static discharge, hardware (i.e., servers, switches, systems, etc.) can become damaged. If a server room stays too dry for too long, systems and servers can crash and cause downtime.

The relative humidity in the server room is too high:

High humidity in the server room can cause metal hardware to corrode. Corroded IT equipment, transformers, generators, and other devices must be replaced. High humidity can also cause condensation to form on hardware, potentially leading to short circuits. Furthermore, humidity is famous for causing mold, which can cause long-term damage to buildings and be extremely expensive to remove.

Why is PRTG the right tool for monitoring humidity in our data center?

PRTG monitoring software keeps an eye on all the environmental values in a data center, including atmospheric conditions. Once per minute, air conditioning systems or individual humidity sensors transmit data from the server room to PRTG. If a threshold value is exceeded, PRTG immediately sends an alert to the administrator or maintenance team.

At the same time, PRTG is much more than just a troubleshooting tool. Its monitoring data provides admins with valuable insight into potential ways to optimize the data center’s environmental conditions. In this way, energy consumption can be reduced without affecting uptime or systems.


 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.

PRTG is customizable and easy to use

PRTG is customizable and easy to use

PRTG is extremely intuitive to use. The first step involves setting humidity thresholds. When configuring humidity sensors in PRTG, you can also customize the intervals at which data is recorded. Next, simply select how you want to be alerted (push notification, SMS, email, etc.) and which employee(s) and/or teams are to receive the alerts.

You can even limit the sending of alerts to specific periods (e.g., only during business hours).

PRTG is reliable and comprehensive

PRTG is reliable and comprehensive

With PRTG humidity monitoring, the readings from your air coolers, dehumidifiers, air conditioners, and ventilation systems are sent from the data center to PRTG at specified intervals. This close-knit monitoring allows admins to immediately take action in the event of potentially dangerous changes in the conditions of the server room.

PRTG is more than just a data center humidity monitoring tool

PRTG is more than just a data center humidity monitoring tool
