With the new major release of PRTG, version 12, we will not only start our continuous rollout concept, but will also include new sensor types, of course. We have picked out some we would like to introduce to you today.

If you want to have a look at the new features and sensor types yourself, please take part in the public beta test and install your personal copy of PRTG 12 today! We'd love to hear your feedback!


Application Sensors—VMware

When it comes to monitoring virtual environments, monitoring hosts and virtual machines running on VMware is our customers' most common request. In the past, we have constantly improved on our VMware sensors. They have become more stable, and we researched a lot to improve performance while obtaining more and more of the vital data you can get out of your vSphere environment. For each virtual machine and each host server, you can already monitor CPU, memory, network, and disk values today. Hardware parameters, as reported by your servers, are also available.


Host Status in vSphere Client
VMware vSphere Client

Now there is a new sensor type VMware Host Server Health which shows a simple overview of the status of all of your host servers' components, as known from your vSphere client. In the sensor details you see the sum of your components being reported as "green", "warning", or "error". This can be a great tool if you do not care so much for exact values, but simply want to be sure that everything is running smoothly and only want to dig in deeper if any irregularities occur.


WMI SharePoint Process Sensor

This new sensor types monitors all vital parameters of a Microsoft SharePoint server. PRTG uses WMI to connect to your server and provides relevant data such as

  • Number of current page requests
  • Number of active threads
  • Number of executing SQL queries
  • Global heap size
  • Cache sizes
  • CPU usage in percent

When adding this sensor type, PRTG adds multiple sensor instances, so you really get all the data you need.


WMI IIS Application Sensor

Similarly, the WMI IIS Application Sensor provides you with all the vital parameters of an IIS server. Customers often requested a sensor of this type, and finally it is here, so you can keep a constant eye on your Windows webserver. For example, the sensor that shows the IIS total utilization presents you values for parameters such as

  • Bytes sent and received
  • Speed of get, post, and CGI requests (number of requests per second)
  • Number of "Not found" errors, per second
  • Number of anonymous and known users, per second
  • Number of files received and sent, per second

PRTG creates multiple sensor instances for IIS monitoring, so you can get separate values for your different web services.

SNMP Cisco ASA VPN Monitoring

There are two sensors available that use SNMP to monitor two values on your Cisco Adaptive Security Appliance:

  • The SNMP Cisco ASA VPN Connections sensor monitors the number of connections that are currently active. You see the number of email sessions, IPSec, L2L, and LB sessions, etc.
  • The SNMP Cisco ASA VPN Traffic sensor is intended to monitor the traffic of permanent VPN connections. It can monitor outgoing and incoming traffic of an IPSec connection and alerts you with a red "Down" status whenever the connection is interrupted.


As with all sensor types, you can, of course set limits for any channel, so you get alerted immediately if certain thresholds are breached.


Fritz!Box Monitoring

Especially our European users will love this new sensor type: The Fritz!Box Wan Interface Sensor monitors the internet traffic running through your Fritz!Box (popular internet access router for SOHOs and small businesses from German manufacturer AVM). Finally, you can also keep records about the usage of your internet line even if your router does not support SNMP. You do not even need credentials to obtain the values—simply add your Fritz!Box as a device, then add the sensor to start monitoring. This enables you to keep long-term statistics of your internet traffic usage, as well.


SIP Options Ping

With this new sensor type you can now monitor if a SIP server in your network is up and running, and if it is possible to place a SIP call at the time. Similar to a VoIP client, PRTG connects to your SIP server, requests the "SIP options," and checks if it can log in using the credentials you provided. This SIP options "Ping" ensures your server is ready for telephony. If the connection to the server fails, the sensor can alert you immediately.


If you already monitor Ping Jitter and the quality-of-service of your network, we believe you will love this new sensor type within your monitoring environment!



Beyond all this, there is also a new Google Analytics Sensor that can, for example, query your website's traffic data from Google. This makes it easy to use this data together with other monitoring data. We, at Paessler, use it with PRTG's Maps feature to create a company dashboard showing the latest statistics.

The new WMI Remote Ping Sensor uses WMI to connect to a target machine, then sending an ICMP echo request from this machine to a specified IP address, e.g. a website. You can use this sensor to easily obtain the Ping time to a certain target from different locations.

Our Xen Host Sensor monitors host servers running on Xen 5.0 or later. As seen in sensors for other virtual environments, it displays CPU, memory, and network usage, as well as other vital system parameters.

There has also been a rewrite of some existing sensor types which we further improved. For example, we now support all of Amazon's different cloud services. Also, the IMAP Sensor now supports checking the content of emails, which makes it perfect for monitoring any email capable backup solution, as well! For more details and a complete list of all new and rewritten sensor types, please see the PRTG history page.
