How to understand API poller output?

Hi,

If anyone has experience with API poller, can you assist me in figuring out the below graphs?

I configured certain thresholds to indicate when it's up/down. If you look at the screenshots, when I hover over the red part I see the same value on the right when I hover over the green part. If the values are the same for the red and green portions, why does it flag the poller as 'down' then?

We have to distinguish two situations here:

Value returned by API Poller exceeds thresholds, its status should be critical or warning.
There is an error in polling, value is not returned. Status of API Poller is Down.

It seems we have the second situation in your example. Polling fails and PerfStack does not show empty values. Please double check what exactly "Red" status means in your situation.

Thanks for the reply. What is the best place to look at the API poller results? Obviously, PerfStack is misleading. I do agree with you that it shows down due to polling issue but I can't seem to figure out what that issue is. If I alert on poller being down, I'd be getting alerts for when the polling failed and have no idea why. If I then were to look at PerfStack it just shows normal values.

Thanks for your help in advance.
