Allowed Number of Cloud Sensors per PRTG Installation
The PRTG cloud sensor types Cloud HTTP sensor and Cloud Ping sensor are available in each PRTG edition (freeware, trial, commercial). They use the PRTG Cloud (just like PRTG push notifications) to monitor loading and ping times of devices like web servers from different locations.
In contrast to all other sensor types, we defined a limit for the supported number of cloud sensors per PRTG installation. The reason for this restriction is that we want to analyze how frequently PRTG users add the cloud sensors to their PRTG installations and test the overall load on the PRTG Cloud first. We will decide after some time if we adjust the limits for the cloud sensor count.
Because of this restriction that comes directly from the PRTG Cloud, you cannot add more than
- 5 Cloud HTTP sensors per PRTG installation,
- 5 Cloud Ping sensors per PRTG installation.
If you add more than 5 Cloud HTTP sensors or more than 5 Cloud Ping sensors to your PRTG installation, the surplus sensors will show a ”down” status with the error message The maximum number of sensors from this type is reached.
Please pause or remove cloud sensors to stay below the sensor limit per type and avoid corresponding alarms on your PRTG server.
Note: Current PRTG versions do not have a hard limit for the number of running cloud sensors. However, we do not recommend that you exceed the limit of 5 cloud sensors per PRTG installation because this scenario is not tested.
Note: The cloud sensors currently do not support IPv6. Please refer to:
