What is the correct process for removing a service alerting?

I have a server that runs nginx service. I want to remove nginx from the server, but the kapacitor still alert. I tried to delete series from influxdb, but it didn't work. What is the correct process for removing a service alerting?

@ws816 Can you share your TICKscript?

I use template to define a task, the template as follow:

var measurement string
var where = lambda: TRUE

var data = stream
  | from()
    .measurement(measurement)
    .where(where)
    .groupBy('host')

var alert = data
  | deadman(0.0, 30s)
    .id('{{ .TaskName }}|{{ index .Tags "host" }}')

alert
  .log('/tmp/deadman.log')

The vars as follow:

{
  "measurement": {"type" : "string", "value" : "procstat" },
  "where": {"type": "lambda", "value": "\"process_name\" == 'nginx'"}
}

What is the correct process for removing a service alerting? remove series from influxdb?

@ws816 Currently the only way to do this is to disable/enable the task. This is because the deadman node doesn't forget any services. There is an open PR #610 to fix this but it has some challenges and we are working on a fix.

@nathanielc Is there another way to monitor process without using deadman? I think the process monitoring is basic requirement.
