How well do you know your OT network?

For a long time “Security through obscurity” was the mantra of the OT Engineer. If a device or network can’t be accessed, it can’t be attacked. Unfortunately, with today’s push towards convergence, this can no longer be relied upon. Actually knowing what assets are in the network can be a big problem in the OT world.

Monitor bandwidth consumption in a PRTG Enterprise Monitor environment

I recently wrote an article that explains how much bandwidth is consumed between the PRTG core server and remote probes. For the sake of context, a few years ago our reseller Omicron AG from Switzerland set up an installation of PRTG with 10,000 SNMP sensors for one of their customers. Within minutes, they could see that they were only generating 400 kbit/s of network traffic for 10,000 sensors with a one-minute scanning interval (which is less than 3 kbit/s per switch)! If you missed it, you can read it here.

Okay, two things are probably clear. We publish outstanding use cases on our blog every now and then – and both PRTG Network Monitor and PRTG Enterprise Monitor are, to varying degrees, made to monitor large IT environments, providing a simple way to gain visibility and control over increasingly complex infrastructures. This is the last part of a four-part series. Are you proudly old school, don't like this newfangled blogging, and would prefer to have your use case as a proper PDF? Who could blame you? You will find the linked PDF on this use case page. iAbout LNA Santé With 30 years of experience, LNA Santé focuses on improving the quality of life for people of any age who are dealing with temporary or permanent medical conditions by providing a welcoming and caring environment.

How to get monitoring data from REST interfaces

These days, REST APIs are just about everywhere. Everything from gateways and firewalls through to ticket systems and weather sites offer REST APIs that let you query information. This represents an opportunity to bring even more data into your monitoring concept. Think of examples like monitoring weather conditions using APIs of online weather sites, or the number of open tickets in your ticket system. To help you harness the flexibility that REST offers, Paessler PRTG provides you with the REST Custom Sensor V2 as part of its monitoring solution.

Get alerted about data center outages with Slack

With 12 million active users daily and 156,000 organizations subscribed to the app (in 2021), Slack is one of the most popular and rapidly growing apps to connect teams, unify their systems, and drive their business forward. It is integrated into the Paessler PRTG  monitoring notification system, which means, in the case of data center outages, PRTG can trigger notifications and send them directly to the Slack channel(s) you want. This sounds convenient, doesn't it? There are also many other notification types you can try, which we covered in other articles that are listed at the end of this article.

Monitoring Modbus in industrial environments

Modbus. It’s a fieldbus protocol that’s been around longer than many of the engineers and technicians who use it. And yet it isn’t going away. Even in 2021, the two common variants of Modbus – Modbus TCP and Modbus RTU – make up 10% of the industrial network market. This is one of the reasons why we included Modbus functionality in our Paessler PRTG monitoring software. We previously wrote about how you can use Modbus TCP as part of your industrial monitoring with PRTG; since then, we also added Modbus RTU capability to PRTG. But what advantages does monitoring with Modbus bring? We’ll get to that. But first, let’s take a look at examples of how you’d use Modbus in your monitoring concept.

Top sensors in PRTG to monitor your Dell, HPE and IBM server hardware

To ensure the smooth operation of a data center, your first priority is to avoid errors and problems with the server hardware. In the age of virtualization, it is crucial to keep an eye on the hypervisors and to eliminate incipient problems before they lead to malfunctions or even failures - regardless of which manufacturer your server hardware is made by.

Monitor your server hardware (system health) with the Redfish protocol

If you monitor your server hardware in your data center with PRTG, you are probably familiar with the System Health Sensor for hardware like Dell, HP, Lenovo, etc., which allows you to monitor the status of the CPU fan, the battery, and also overall system status, among other things. Each sensor includes numerous channels that let you keep a detailed eye on your hardware. But did you know that PRTG also lets you monitor the system health of your server hardware via the Redfish protocol?

How Paessler reduces electronic waste and is closing the loop

The concept of Closing the Loop in itself is very simple. For every workplace device a customer buys, a corresponding amount of electronic waste is recycled – with a clear focus on Africa, where electronic waste is a ubiquitous problem. In the pre-Corona year of 2019 alone, the world accumulated 53.6 million tons of e-waste. That's an almost indescribably large number. And the annual amount of electronic waste will continue to increase, as also stated by the Global E-Waste Monitor 2020. Those that suffer the most from this development are developing countries. When we found out about Closing the Loop, it was clear to us that we wanted to be a part of it. After all, if you read our blog regularly, you know that we are committed to the reduction of resource consumption.
