Got a newb question here, but I'm thoroughly confused over how channels get created when adding sensors. Specifically, I'm having a problem with Cloud HTTP sensors.
When I go to add a new Cloud HTTP sensor, there is no option for which channels get created. But some of my sensors have been created with 6 channels, others 8, and others still have 10. There does not seem to be any rhyme or reason to it.
My organization has region-blocking in place, so I only want to monitor these from the US West and US East regions (both by Response Time and Response Code). So, along with the Downtime and Global Average channels, that would be a total of 6 sensors. And that's what I got on a few of the ones I created, but others also had the EU and/or Asia regions, which I don't want.
I can't find a way to remove channels... indeed, it sounds like that's not possible. Which I have no idea why this capability wouldn't be available (seems pretty basic to add/remove a channel), but I digress.
So, since I can't figure out what is causing the sensors to get some channels and not others, I tried cloning the sensors with just the 6 channels I wanted. That has not always worked. Let me repeat that: I CLONE A SENSOR WITH 6 CHANNELS AND SOMETIMES, BUT NOT ALWAYS, IT WILL CREATE A SENSOR WITH 8 OR 10 CHANNELS. That makes NO sense to me. Why is this happening?
Would someone kindly enlighten me as to the following:
- How do I control which channels get added to a sensor
- Is it possible to add/remove channels from an existing sensor? If so, how?
- How is it that if I clone a sensor the resulting channels differ from the one being cloned?
