How to run a PRTG core server with >5,000 sensors in a virtual environment

I guess the following article might be interesting for some of you with a larger PRTG installation. Up until recently (i.e. until August 2020), we at Paessler had provided support for installing PRTG on a VM with up to a maximum of 5,000 sensors or, more precisely, a sensor range of 2,500-5,000 sensors. In practice, this corresponds to an average of about 500 monitored devices and is still supported as per our PRTG system requirements.

How to build a centralized overview for monitoring enterprise IT

One of the biggest challenges with monitoring enterprise IT — which we define as environments with over 1.000 devices — is getting a unified overview. In such large environments, you almost certainly have several monitoring servers collecting data from different parts of your infrastructure. This leads to all kinds of problems, such as alert noise or multiple monitoring tools; but the biggest issue is that it causes you to lose sight of the overview. When this happens, you can't gauge the health of your entire infrastructure at a glance anymore. But how do you bring data from multitudes of devices and sources in different locations into one centralized overview?

Turning old into new: Optimization of brownfield plants

The production environment continues to prepare for a digital, more efficient future. In this sector, digitization or digitalization are often paraphrased with the somewhat cryptic, but ultimately meaningful terms greenfield and brownfield. While a greenfield industrial plant is built on a "greenfield site", completely new and according to specific ideas, a brownfield scenario is one where an existing plant is being digitally modernized. It is obvious that brownfield (or retrofitting - the two terms are often used interchangeably) is the much more attractive choice for most existing plants. This article is part 1/2 of a short series on the topic of retrofitting.

PRTG and Sonoff smart meter part 2 - MQTT strikes back

Back in the mists of time (March 2019), I wrote a blog post describing how a REST Custom sensor can be used to read energy consumption data from a Sonoff POW2 smart switch. One of the cool features provided by the Tasmota custom firmware used in that project is support for the MQTT protocol.

Introducing the new Microsoft 365 sensors in PRTG

Just before the release of PRTG Network Monitor 20.3.61, Microsoft renamed its powerful software suite from Office 365 to Microsoft 365. Therefore, the two new sensor types are now called Microsoft 365 Service Status Sensor and Microsoft 365 Service Status Advanced Sensor.

4 Ways to reduce alert noise in enterprise IT

Enterprise IT — which we (Paessler) loosely define as infrastructure with over 1,000 devices — is a special beast to manage, with many challenges to overcome. One of the biggest issues that IT teams in these large environments face is alert noise. This happens when you're monitoring your infrastructure, network, storage, cloud services and other elements of your IT, and generating alerts and notifications for failures or impending failures. Too much alert noise makes it downright difficult to identify serious problems, and it might even mean ignoring alerts and missing what really matters. Your monitoring efforts are compromised, and the quality of your service goes down.

Office owl, flexible flamingo, or remote raccoon? How we at Paessler are changing the way we work

The way people work in offices has been changing constantly ever since offices came into existence, although transformation is dependent to a certain extent on culture. The concepts of open-plan design, which right from the start were successful in North America, have had a hard time in Europe. Ideas such as remote work have taken a long time to gain recognition in the minds of Europeans as a valid means to an end, whereas already in 2010, President Obama signed the Telework Enhancement Act, requiring all federal agencies to create policies for eligible employees to work remotely. Between 2014 and 2018, the number of fully-remote US companies jumped from 26 to 170. Also in 2018, 53% of the world’s population worked remotely for at least half the week. As so often in history certain unforeseen events serve as a catalyst for further development. In addition to the catastrophic effects of the coronavirus crisis on all of us, office work has been reinterpreted around the globe. We at Paessler have not been exempt from this phenomenon. In some blog articles at the beginning of the crisis, we already shared with you how we have continued our work with the usual standard of quality and are always there for our customers; just not in the office – but from home. This article is partly a personal report, partly a description of how we at Paessler are working during the "time of corona" and how we will work in the future.

Another 6 new sensor types in PRTG Network Monitor 20.3.62

After our last release in August with 5 brand new sensor types, PRTG version 20.3.62 again brings a lot of new features. Besides improvements in the context menu and a new notification method, we are happy to present no less than six new sensor types! These are as follows:

Corona distance-tracking solution with Cisco Meraki and PRTG

Do you remember the summer of 2019, when we danced together at music festivals, populated beaches and went to the supermarket without being counted at the entrance? And all of this without a face mask? In 2020, many things have changed. Suddenly there is this fear of the virus, you pick up the word "Corona" in just about every conversation and much of the former easygoingness is suddenly gone.

INSYS icom and PRTG: a use case in getting data from the factory floor

In an industrial IT environment, IT and Operational Technology (OT) have for a long time been two separate worlds. But recent digitization has started changing that, which means that combining these two aspects in your monitoring concept has become vital.

In March 2020, Gartner gave away fifty $25 Visa gift cards for published reviews on their Peer Insights review portal. Now, with a new Gartner program, we are able to sponsor another 50 cards.  How to get one?  

Introducing the new Zoom Service Status sensor in PRTG

Remote working and teaching is becoming increasingly common in companies and schools across all countries. Today, more and more people, students, and pupils are working and learning from home. As a result, companies and educational institutions need to ensure that their staff have the tools to provide the best communication experience within their own four walls.

Let's ping your network

Ping is a command-line tool available for practically any operating system with network connectivity and is used as a test to determine if a network device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the pinging computer back to the original computer. Below we will show you what ping and latency actually are, why measuring them is so important and how PRTG can save you a lot of work and time. Let's get started!

Our new MQTT sensors: video tutorials

Over the past few months, we've rolled out several new MQTT sensors for PRTG Network Monitor that enhance the capabilities for monitoring the IoT and IIoT. In the near future, I'll be giving you some examples of use cases to demonstrate their usefulness in industrial IT, but for now, we put together some tutorial videos to show you how to use the sensors.
