Highest Alreting Sensor Report

Dear Divyesh Desai

Please specify in which sense you want to see the "highest alerting" sensors.

I believe he wants to pull a report or a sensor that had most erroneous states (Warning / Error) from a certain group in a given time frame. I'm not sure but it sounds as that what he is looking for. That said, even if I'm correct and that is what he is looking for, I don't know how to pull such a report.

Dear David

This is not possible with PRTG itself.

You can compute the downtime for a particular time frame when you use the API to export historic data. However, it is not feasible to do this for every sensor, as this API call generates high load on the system.

The best option for any custom reporting task not supported directly by PRTG is to use the Data Extractor: https://www.paessler.com/tools/dataextractor

This application exports the historic data to an SQL database, allowing to use PRTG data with reporting suites or custom scripts to generate any kind of report.

Of course, data extraction also puts load on the system, but if you do it for example once per week, in the night, it is still a viable option.

Is this still not possible? I mean a report to display the top 10 sensors the generate the most alerts/alarms?

Dear Ariel,

it is not possible to sort for the number of status changes. Only channel data (like downtime, or primary channel values) can be used, evaluating numeric data.
