Our latest PRTG version 20.3.61 has been available for download in the stable channel for a few days now, and the release is a blast! No less than **134 resolved issues** including **5 new sensor types**, **4 updated language files** and dozens of other neat improvements and fixes. But first things first, let's take a look at the new sensor types, they’re called... [![prtg network monitor 20.3.61 includes 5 brand new sensor types](https://blog.paessler.com/hubfs/2019/visuals/header/header-new-prtg-release.png)](https://blog.paessler.com/prtg-network-monitor-20.3.61-includes-5-brand-new-sensor-types) - Microsoft 365 Service Status sensor - Microsoft 365 Service Status Advanced sensor - Zoom Service Status sensor - Dell EMC Unity Storage LUN v2 sensor - MQTT Subscribe Custom sensor ## Microsoft 365 Service Status Sensors PRTG 20.3.61 includes two new sensor types for Microsoft 365 (formerly known as Office 365) monitoring. While the [**Microsoft 365 Service Status sensor**](https://www.paessler.com/manuals/prtg/microsoft_365_service_status_sensor) shows the overall status of all services of a Microsoft 365 subscription, you can use the Microsoft 365 Service Status Advanced sensor to monitor the detailed status of a specific service. With the help of the Microsoft 365 Service Status sensor, you can see the status of your Microsoft 365 services at a glance and you can immediately step in before the workflow of the entire company is affected if there is an issue. It shows the total number of operational services, degraded services, interrupted services, and services in warning state.  ![20361-microsoft_365_service_status](https://blog.paessler.com/hs-fs/hubfs/2020/visuals/Body/20361-microsoft_365_service_status.png?width=1015&name=20361-microsoft_365_service_status.png) The [**Microsoft 365 Service Status Advanced sensor**](https://www.paessler.com/manuals/prtg/microsoft_365_service_status_advanced_sensor) monitors the detailed status of a service of a Microsoft 365 subscription. With this sensor, you get a detailed status of all Microsoft 365 applications and products you are subscribed to like Microsoft Teams, Exchange Online, Skype for Business, OneDrive for Business, or Planner. You can individually define which Microsoft 365 services you want to monitor and create a sensor for in the Add Sensor dialog. ![20361-microsoft_365_service_status_advanced](https://blog.paessler.com/hs-fs/hubfs/2020/visuals/Body/20361-microsoft_365_service_status_advanced.png?width=1008&name=20361-microsoft_365_service_status_advanced.png) ## Zoom Service Status Sensor Perfectly suited for the unusual year 2020 with its global pandemic, various lockdowns and a growing remote work culture, the new [**Zoom Service Status sensor**](https://www.paessler.com/manuals/prtg/zoom_service_status_sensor) also comes with this PRTG version. The sensor monitors the global status of each Zoom service ([https://status.zoom.us](https://status.zoom.us/)) and shows the operational states of the services and according error messages if something went wrong. ![20361-zoom_service_status](https://blog.paessler.com/hs-fs/hubfs/2020/visuals/Body/20361-zoom_service_status.png?width=1436&name=20361-zoom_service_status.png) ## MQTT Subscribe Custom Sensor PRTG also continues further development in the field of Industrial IoT. This means a third MQTT sensor is now available! The [**MQTT Subscribe Custom sensor**](https://www.paessler.com/manuals/prtg/mqtt_subscribe_custom_sensor) subscribes to an MQTT topic and monitors the returned values. It can show up to five numerical values from the received JSON data. ![20361-mqtt_subscribe_custom](https://blog.paessler.com/hs-fs/hubfs/2020/visuals/Body/20361-mqtt_subscribe_custom.png?width=988&name=20361-mqtt_subscribe_custom.png) My fellow colleague [Michael](https://blog.paessler.com/author/michael-becker)already wrote a blog article about our three MQTT sensors in PRTG – I recommend that you read this article: [Introducing the new MQTT sensors for PRTG](https://blog.paessler.com/introducing-the-new-mqtt-sensors-for-prtg) ## NEW: Dell EMC Unity Storage LUN v2 Sensor Our new [**Dell EMC Unity Storage LUN v2 sensor**](https://www.paessler.com/manuals/prtg/dell_emc_storage_lun_v2_sensor) supports the Unity REST API version 5 and later, which the existing REST Dell EMC LUN BETA sensor does not support. The sensor monitors a LUN (logical unit number) on a Dell EMC Unity storage system and shows the health status of the LUN, as well as several size metrics. If you run a Dell EMC within your IT infrastructure, you should definitely check out this sensor! ![20361-dell_emc_unity_storage_lun_v2](https://blog.paessler.com/hs-fs/hubfs/2020/visuals/Body/20361-dell_emc_unity_storage_lun_v2.png?width=1000&name=20361-dell_emc_unity_storage_lun_v2.png) ## Improved Core Health Sensor, Auto-Discovery and Notification Delivery As always, a new PRTG version comes with a lot of other changes that make life easier for you. We equipped the **Core Health sensor** that monitors the status of the PRTG core server with **three new channels**. The new channels show the number of Notifications in Send Queue, the Number of State Objects, and the number of Probe Messages per Second. You can now see **if an auto-discovery for a device is in the queue** in the device tree. In this case, the device will show the message *Auto-Discovery pending*, for example, when auto-discoveries are already running on 10 other devices at the same time. It is now also possible to **test the configuration of an optional fallback SMTP relay server** in the Notification Delivery settings. PRTG will try to send a test email to both SMTP relay servers if you click the Test SMTP Settings button. ## Plus some more changes and fixes Aside from all of that, we also fixed **40** bugs, implemented **40** feature and story tickets, and finished **54** tasks and to-dos with PRTG 20.3.61. Find all the details [on our release notes page](https://www.paessler.com/prtg/history/stable#20.3.61.1649). ## 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 always see which features we are currently working on and what kind of things we want to implement in PRTG in the future.
