Kapacitor not triggring alert

I am not getting alert in alert history. I have installed kapacitor and chronograf in one machine and influxdb in another. I tried setting alerts from chronograf Ui, but alerts are not getting triggered. I run “kapacitor list tasks” in the machine where kapacitor is installed and there all the alerts are visible but still I cannot find why alerts are not getting triggered.

Is this post a duplicate of Kapacitor not triggring relative alert or are you running into a different problem here?
