We have an XML/HTTP sensor which is only supposed to measure the value of a specific XML node. On the "Overview" tab we can also see the "Execution time" for this HTTP request, which is completely irrelevant for this sensor, so we have chosen "Hide in graphs", "Hide in tables" and "Disable limits" for this sensor. So far so good.
However, the "Unusual Detection" reacts on the execution time of this sensor, showing this sensor as having an unusual value, even though the relevant value from the XML node has been exactly the same for several months.
How do we stop the "Unusual Detection" from reacting to irrelevant channels? As I have understood from reading other forum posts, it is not possible to delete the channel in question.
