You can use “kapacitor show < task name >” to see the output from the task itself. I tend to do that, then tail my kapacitor logs for the taskname so i can see when it runs.
Have you tried swapping the |influxDBOut and |Alert nodes around?
I was trying different permutations and combinations yesterday and it worked when i moved the alert above the influxDBOut. But Unfortunately, i couldn’t figure out the reason behind and hence kept the question opened.
