Since January 22nd, **PRTG version 20.1.55 is available for download** in our stable release channel. And once again, the new version has a lot of new features and improvements.

The new version includes **two new sensor types for monitoring Nutanix HCI infrastructures**, an indicator for the performance impact of running sensors, a modernized password reset approach, an updated Python distribution, TLS 1.2 as default web server connection security, a major change to stabilize probe connections, and much more. So let’s take a closer look at some of the new features.

## New SNMP Nutanix Cluster Health and SNMP Nutanix Hypervisor sensors

With PRTG 20.1.55, we enter the world of Nutanix monitoring, a vendor of hyper-converged infrastructure (HCI) appliances and software-defined storage.

The new [SNMP Nutanix Cluster Health sensor](https://www.paessler.com/manuals/prtg/snmp_nutanix_cluster_health_sensor) monitors the status of a Nutanix cluster and shows whether it is "started" or "stopped", for example. It also provides an overview of several performance metrics like I/O operations per second, used I/O bandwidth, and I/O latency.

The other new Nutanix sensor is the [SNMP Nutanix Hypervisor sensor](https://www.paessler.com/manuals/prtg/snmp_nutanix_hypervisor_sensor). This one monitors several performance metrics of a Nutanix cluster hypervisor, like CPU usage, traffic, and I/O data, as well as the number of active virtual machines on a node.

## More transparency about the sensor performance impact

In the past, the only way to get information about the performance impact of a sensor was the PRTG System Status page, or via the “Add sensor” dialog. As soon as you deployed a sensor via auto-discovery, you never learned about the performance impact of that sensor. This is why we made the performance impact more transparent.

In the **sensor's overview**, you will now see the performance impact together with the rest of the sensor's properties (at the top right corner). Hovering over the icon shows more details (e.g.: Medium impact, try and stay below 500 sensors per probe). 

And this is how it looks:

iKeep in mind that a sensor's performance impact usually refers to the sensor's performance impact on the probe. This is important to distinguish between issues related to a bottleneck on the probe (too many sensors on one probe) or core performance issues (too many total sensors on a single core server).

 

Additionally, the exact performance impact also depends on the scan interval of the sensor. A 10-second scan interval has a higher overall impact than a 5-minute scan interval.

## New version of the PRTG Certificate Importer

By default, PRTG is delivered with a self-signed SSL certificate so you can use secure connections to your PRTG core server. If you want to exchange this certificate for a signed certificate or a certificate from your company, you can import this in different ways. You can either [set up the certificate manually](https://kb.paessler.com/en/topic/283-how-can-i-use-a-trusted-ssl-certificate-with-the-prtg-web-interface) or - much easier and more handy - use our PRTG Certificate Importer.

We have refreshed the PRTG Certificate Importer and you can [download the latest version here](https://www.paessler.com/tools/certificateimporter) together with step-by-step instructions on how to use it.

## What else happened?

| **Improved password reset approach** | The way how you reset your password has been modernized. The approach consists of receiving a link by email from where you can set the new password. |
| --- | --- |
| **Improved Geo maps** | Improved messaging has been added to the geo maps feature. Geo maps now tell you what went wrong if PRTG is not able to retrieve geographical maps. |
| **Improved reports** | An issue with the height of certain graphs in reporting has been fixed. The height of main and monthly graphs is now consistent in all report templates. |
| **Changes in Web server connection security and Python** | TLS 1.2 is now the default web server connection security. We also no longer support Python 3.4; it’s Python version 3.7 now! |

All in all, since the release of [PRTG version 19.4.54](https://blog.paessler.com/prtg-release-19.4.54-includes-2-brand-new-sensors-for-disk-and-storage) we included more than 120 improvements to the software, the sensors, the language files, the reports and the web interface. See the [PRTG release notes page](https://www.de.paessler.com/prtg/history/stable) for details and all other changes in the latest versions.

## Check out our public roadmap

We also offer a [public roadmap of PRTG](https://www.paessler.com/prtg/roadmap) on our website. There you can read at any time which features we are currently working on and what kind of things we want to implement in PRTG in the future.
