Chronograf not saving Alert Rule of Type: Deadman

I’d like to setup DNR (Data Not Received) alert for which I use Alert Type: Deadman. I hope that’s the proper type for this purpose.
Essentially I wanna be alerted when there is no new data in the db in the last 10 minutes.

So I do all as usual:

  1. Build a query in Select a Time Series - see below on picture
  2. Select Alert Type: Deadman and …missing for: 10m
  3. Send Alert to log
  4. Put a name of the Rule
  5. Click Save Rule
  6. Get Rule successfully updated! box
  7. verify the rule in kapacitor - posted below.
  8. refresh the webpage in Chronograf (or navigate in left pane Alerting -> Alert Rules -> select the actual Rule)
  9. Select a Time Series and Rule Conditions are empty!! :face_with_raised_eyebrow:

After refresh:

Hi,
I have exactly same issue… did you find the solution?

No sir :unamused:

So either we both do something wrong :slight_smile: …or it’s a legit bug in Chronograf and we should report it as issue on github…

…and therefore I submitted one https://github.com/influxdata/chronograf/issues/1890
