Hi,
With my limited knowledge, here is a small tip to debug the things. It appears that you are using chronograf to set the alerts. When u enter
alerts tab --> Manage Tasks--> Build Alert Rule
After setting up the Rule, It will create a automatic TICK Script associated with the Alert Rule. I think it would be nice if you can copy paste the TICK script in the query. so that some one else can debug.
Secondly don’t forget to enable the rule. In my case i disabled all of them - “Task Enabled” column.
Once you understand little bit of TICK scripts you can edit by adding http outputs node once in a while to see the data flow. example Problem with evaluation node - TICK script
