I get following error while creating an Kapacitor alert. Alert is created but not triggered.

ts=2018-08-21T15:01:05.329Z lvl=error msg="failed to create database" service=kapacitor task_master=main task=chronograf-v1-2004f027-091f-4af9-b5c8-a636ab28fcc8 node=influxdb_out8 err="retention policy conflicts with an existing policy" database=chronograf cluster=

Retention policy defined on influxdb database is defined as following.

        .measurement(outputMeasurement)
        .tag('alertName', name)
        .tag('triggerType', triggerType)

trigger
    |httpOut('output')

Any suggestions?

Answer 1

The conflict i guess is that you are trying to create the same db.

"retention policy conflicts with an existing policy" you may need another rp.
