Viewing alerts in Chronograf

I have created TICKscripts that run as part of my kapacitor and generate alerts which are stored in ‘alerts’ measurement of ‘chronograf’ database in InfluxDB. But these alerts don’t show up in the alert history page of Chronograf. It is supposed to be viewable as per link

Below is the alerts measurement:

> select * from chronograf.autogen.alerts
name: alerts
time                alertDuration alertMessage                              alertName       deviceId perf_stat_delay_sec severity triggerType
----                ------------- ------------                              ---------       -------- ------------------- -------- -----------
1559026533000000000 327843234862  latePerStat/device1 is OK value:2         LATE_PERF_STATS device1  2                   OK       custom

In chronograf, I am able to see the task listed in “Manage Tasks” section but not the alerts generated by the task.

Seems to be a basic feature, which I am not able to figure out how to get it working. Any pointer would help.
