Dear elliott-pd,

as the images are not visible, please contact us at [email protected]. Please include the description of the issue, and the screenshots as file attachment (up to 10 MB combined attachment size.)

I've attempted to edit the post with correct links, but it fails.

Dear elliott-pd,

thank you; however these screenshots are cut-outs. This removed important context. Please capture the full interface of PRTG in the screenshot. In addition, the "Overview" tab of the sensor would be helpful as well.

Hi Arne,

Here are full page screenshots as per your request. I've also attached direct links to the images, as they seem to be displaying weirdly.

For additional information about what we are trying to monitor. We have a service setup that processes incoming messages, each time a message is successfully processed we increment a performance counter by 1. Each morning we reset all of the performance counters to 0. This service does run 24 hours a day, but we want to monitor it during certain business hours (9am-8pm) with a 2 hour window for lunch which is ignored. Outside those hours the sensor is turned off, as there won't be any data for the service to process.

We expect a constant flow of messages, but it is a low amount. Only about 48K over the course of a business day. The average per second will be low, usually under 1 depending on how busy the service is. If there is a period of 10+ minutes where there has been 0/s, we want the sensor to go down so that we can investigate this. As it indicates the service is not processing any messages.

Here are the direct image links, as once posted they seem to show weird dimensions (likely because the images are so large).

Dear elliott-pd,

thank you. Please also send the historic data for that time frame, so that I can check it. The latest trigger according to the screenshot was on August the 28th, 10:44:22.

Hi Arne,

Here's a link to the historic data for 24 hours on that sensor.

Dear elliott-pd,

I saw that you are already in contact with one of my colleagues. Please follow-up that case, as it is easier via email than through the knowledge base.
