The kapacitor can't alert after the task was reloaded.

[ghost]

I have 10 nginx servers that are using kapacitor for alerting. The TICKscript as follow:

var data = stream
  |from()
    .measurement('procstat')
    .where("process_name" == 'nginx')
    .groupBy('host')

var alert = data
  |deadman(0.0, 30s)

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

The kapacitor can normally alert after a nginx was dead. But It can't alert after a nginx was dead while the task was reloaded. It's so weird.

If I really want to remove a nginx server in another case, what should I do?

deadman watches for something to go from there to not there for a while. It can't tell which hosts you have if it doesn't receive at least one data point from the host.

one option would be to sideload some points that have the hosts you want to monitor so it can tell what it is supposed to monitor.
