Scanning Interval

We have a custom sensor with a scanning interval set to @ UTC 07:10, 15:10, 23:10

However it runs at a higher frequency causing unwanted triggers when the query fails. There is no inheritance set but it acts like there is

Example

Hello there,

Thanks for your inquiry, we appreciate your contact regarding the matter!

To understand your configuration right, your Sensor is paused in the night by a schedule until 7:10 and then running in an 8 h scanning interval. Am I right? If not, please explain this in more detail for me. You can also send screenshots to support@paessler.com. Please use a subject that includes the ticket number PAE1009678.

In the table you sent, it seems that some scans are running due to a manual "check now".


Kind regards,

Hi..

We don't manually run the scans but just rely on the interval of three times a day as you have said. That's all we expect to see assuming the scanning interval setting with PRTG does the scheduling internally. The script has no schedule component.

We don't do any "manual check now" - the data is from the sensors metrics

Hi Alex,

A sensor is only running a scan before its interval when the following happens:
- someone runs a check now on one of the corresponding objects (Root, Probe, Group, Device, Sensors)
- The Probe connection got interrupted
- The sensor gets paused. This can happen due to inheritance, schedules, maintenance windows or manual pauses

If "check now" was executed by a user, you can see this in the current web server logs (default path: C:\ProgramData\Paessler\PRTG Network Monitor\Logs (Web Server)). Search here for the corresponding sensor ID. This is displayed in the upper right area of the sensor overview.

I would recommend to change the schedule, that the Senor is not running between the intervals, to prevent false alarms.


Kind regards,
