PRTG licensing is measured by so-called sensors. To purchase the license that fits my needs, I would like to know:

This article applies to PRTG Network Monitor 19 or later
In PRTG, sensors are the basic monitoring elements. One sensor usually monitors one measured value in your infrastructure, for example, the traffic of a switch port, the CPU load of a server, or the free space of a disk drive.
On average, you need about 5-10 sensors per server or one sensor per switch port.
All licenses of PRTG only differ by the maximum number of sensors that you can use for monitoring. For more information, see also the PRTG price list for details.
Note: When you buy one license now, you can upgrade to a larger one at any time.
In PRTG, you create devices that represent the actual devices, servers, databases, and more in your network. Then you add sensors to these devices.
For example, when monitoring a firewall, an Exchange server, and a printer, you can use the following sensors:
| Device | Possible Sensors * |
| FIREWALL | Ping |
| Interface #01 | |
| Interface #02 | |
| Interface #03 | |
| Interface #04 | |
| Interface #05 | |
| Interface #06 | |
| CPU Idle Percent | |
| DNS | |
| UDP Datagrams In | |
| UDP Datagrams Out | |
| SNMP Messages In | |
| SNMP Messages Out | |
| HTTP | |
| EXCHANGE SERVER | Ping |
| CPU Load Processor 1 | |
| CPU Load Processor 2 | |
| RAM Memory | |
| Network Card Traffic | |
| Disk Free | |
| SMTP | |
| IMAP | |
| POP3 | |
| RDP | |
| MSExchange Mailbox Send Queue Size | |
| MSExchange Mailbox Receive Queue Size | |
| POP3 Round Trip | |
| Fan 1 Speed | |
| Fan 2 Speed | |
| Disk Array | |
| Board Temperature | |
| PRINTER | Toner Status |
| Paper Status | |
| Jam Status |
* This is meant as an example only. It depends on your device and your network configuration which sensors you can actually use.
The number of sensors that is necessary for your individual setup depends on how closely you want to monitor your network. It is your decision whether you set up general Ping and Port monitoring for a device, or whether you monitor it very closely, including many different performance parameters.
Note: As a rule of thumb, you can calculate with about 5 to 10 sensors per device.
There are more than 250 different sensor types available in PRTG. For a complete list, see the PRTG Manual: List of Available Sensor Types.

I just configured a new environmental temp/humidity sensor. My question is how do I monitor temperature and humidity levels in PRTG? There doesn't appear to be any documentation in this regard.

Hello,
Thank you for your KB-post.
Which hardware do you use for monitoring of temperature and humidity / what is a vendor of your sensor?

Hello,
Kindly note that PRTG doesn't have any default sensors that can read data from PCBs.
Some customizations will be necessary here, but that depends on capabilities of the hardware you use.
Depending on the type of output, you can try using some of our Custom sensors or maybe HTTP XML/REST Value Sensor.
Best regards
