PRODUCT OVERVIEW

Take control of your network with PRTG’s user-defined threshold values

When you’re in data analytics, network management, or systems administration, you already know specific threshold alerts are time, money, and resource savers. Threshold monitoring with Paessler PRTG helps you gain even more control of your network and IT infrastructure, including devices, systems, traffic, and applications.

Monitor your network devices and actions

IT environments can be complex, and networks are no exception. Between routers, switches, firewalls, load balancers, and other network hardware, you can have several vendors, connections, and software. PRTG can monitor network traffic, performance, and errors via multiple technologies, providing a central reporting source for your network.

Watch your server performance metrics

If you have more than one type of server, you aren’t alone. You can struggle with monitoring all those metrics manually, or you can rely on PRTG threshold monitoring. From web, database, and file servers to mail and storage servers, PRTG will monitor your server performance and health, and alert you when your configured thresholds are reached.

Keep your virtual machines close

Virtual environments don’t have to feel a mile away – PRTG adds a virtualization layer to check your virtual machines. Monitor platforms like VMWare, Hyper-V, and Citrix Xen using individual warning and error thresholds. See the performance and status of your VMs, and get customized notifications sent to key stakeholders when issues arise.

Direct your bandwidth usage and data flow

Bandwidth is a finite resource for any organization, so finding, identifying, and troubleshooting bandwidth bottlenecks quickly is important for a healthy and efficient network. PRTG threshold alerts notify you before you reach maximum capacity, so you can allocate the resources in use differently or plan for new resources even before they’re needed.

Gauge your CPU temp and performance

Always keep an eye on the most important hardware parameters. PRTG notifies you when the temperature of your CPU reaches the limits you’ve set. Also get alerts if early-stage bottlenecks appear, CPU usage soars, or the load is too high. Threshold monitoring with PRTG sends the notifications you need as soon as an issue appears so you can quickly find a solution.

What threshold monitoring looks like in PRTG

Diagnose network issues by continuously tracking hardware, applications, web services, and more, using custom threshold baselines. Show bandwidth usage, availability, CPU utilization, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot network and infrastructure issues based on performance thresholds.

3 reasons to choose PRTG as your threshold monitoring tool

icon workstation

Network management in God mode

PRTG gives you the power to monitor and manage your entire network and IT environment across servers, devices, vendors, service providers, and more.

PRTG can be fully integrated into your network or only monitor a single device. It’s up to you how many devices you monitor in your network. It just needs an IP address to add it to your monitoring setup. Customize PRTG to meet your own needs and requirements.

icon alarm

Threshold values for the best alert system

Don’t get bothered by unnecessary alerts. PRTG makes it easy to configure your threshold values to match the needs of your IT ecosystem.

Set your threshold alerts to higher sensitivity for critical devices adversely affected by minor deviations. Set them to lower sensitivities for systems and devices that have a higher performance variability, so you aren’t bothered by unnecessary alerts.

icon maps

Easy-to-understand reports and visualization

View the status and health of your devices at a single glance. Using a simple traffic lights system for visualizing warnings (yellow), errors (red), and everything that’s running as expected (green), you can see immediately when an issue arises.

You can also create reports of capacities over specific time periods to recognize trends. PRTG reports are easy to understand and help you determine the capacity of your network at a glance.

PRTG is compatible with all major vendors, products, and systems

PRODUCT OVERVIEW

”Adopting PRTG has been like going from being in the dark to being in the light. Before, we had limited visibility into what was happening in the infrastructure and in the network. Now, however, thanks to the comprehensive dashboard and real-time notifications, we receive constant updates on the status of facilities and services, and our way of working has gone from passive to proactive.”

Naples International Airport

”As an international company, PRTG is ideal for us. If something went down half way across the world, we wouldn’t be woken up – we can rely on PRTG to identify the problem and alert us before it occurs – enabling the right person, in the right time zone to resolve the problem. At the end of the day, if we’re to provide an internal network experience for our employees that meets expectations, we need a tool like PRTG to be successful.”

Threshold Monitoring: FAQ

 

What is threshold monitoring?

Threshold monitoring is a technique used in various fields, including computer science, finance, and environmental science. It involves setting predefined thresholds or limits for certain parameters or variables.

These thresholds act as benchmarks for normal operation or acceptable levels of a particular metric. When the observed value of the parameter exceeds or falls below the set threshold, an alert or action is triggered, indicating a potential issue or deviation from the expected behavior.

How does PRTG monitor thresholds?

PRTG uses sensors to monitor networks and IT environments. These sensors are preconfigured but customizable, so you can use the most common configurations or set individual threshold values to meet your needs. When a designated metric gets close to the threshold, PRTG sends an alert to the key stakeholder.

For example, the SNMP CPU Load sensor monitors your CPU performance. PRTG comes with preconfigured sensors for all the biggest manufacturers, including  Cisco, IBM, Dell, and HPE. What’s more, all your CPU threshold values are customizable. PRTG will automatically (and promptly) send you an alert – before the system goes down.

What do the different thresholds in PRTG mean?

Different thresholds represent various states of performance, resource usage, or operational health. They help to distinguish between when things are operating normally and when there are potential issues. Thresholds in PRTG include:

  • Error: set for the most critical conditions that require immediate intervention, such as those that significantly impact system performance.
  • Warning: a metric is approaching critical but hasn’t reached a point of immediate concern. This is where threshold monitoring really makes itself shine, stopping issues here before they become critical.
How easy is it to configure threshold values in PRTG?

For many sensors, it only takes a few short minutes:

  1. Create the sensor in PRTG.
  2. Open the channel settings.
  3. Set the upper and lower “warning” and “error” limits and define the corresponding sensor messages.
  4. Save your settings.
  5. Your PRTG speedometer should now have a yellow section for warnings and a red section for errors.
What is a sensor in PRTG?

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

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
