Server availability monitoring with PRTG

Server Uptime is essential

Uptime is one number that is critical to an IT department and their management. When your servers are available then your IT services are available. Server availability includes monitoring that your hardware is up and available, that your virtual infrastructure is available, and also your critical applications and services such as databases, email, active directory, web servers, and file services to name a few.

Monitor your Remote Servers

With PRTG Network Monitor you can have that up-front view into your remote servers – you know what they are doing and how they are doing in real time and IT administrators can view historic metrics to evaluate trends. With our out-of-the-box support for multiple hardware vendors you are able to get metrics returned that are specific to your servers.

A sneak peek into PRTG Server Availability Monitoring

PRTG offers sensors for multiple hardware vendors



iWhat is a sensor?

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 Network Monitor has sensors for multiple hardware vendors out of the box:

Dell Poweredge

The Dell Poweredge System Health Sensor uses SNMP to monitor and report on the overall system health of a Dell Poweredge Server – including power supply, memory, temperature and cooling device.

Dell Hardware

The Dell Hardware Sensor shows values returned by Dell specific OID values such as the system management software and hardware parameters.

HPE ProLiant

The SNMP HPE ProLiant System Health Sensor can monitor and alert on multiple aspects of your HPE ProLiant Server from fault tolerant fans to the temperature of multiple hardware components. This sensor also includes a channel for the Integrated Management Log.


The IBM X System Health Sensor can provide alerts and metrics on the voltage of planars, revolutions per minute of fans, status of power supplies and the temperature of CPUs.

Generic SNMP and WMI Sensors ensure server availability

PRTG has several generic sensors to ensure server availability in both the SNMP and
WMI protocols:


The SNMP Windows Server sensor and the WMI Service Sensor are both monitoring if a windows service stops and can restart it for you ensuring the continuity of your critical windows server services.

The WSUS Statistic Sensor gives you peace of mind that your Windows servers have received their critical patches.


iA server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers. There are many types of servers, including web servers, mail servers, and virtual servers.
