Alerts on derivatives in elastic

[Anmol_Dubey]

I am trying to create an alert when average of my derivative data exceeds a threshold, but am not able to figure out how to do calculations on returned values in kibana

Grafana graph of the data looks like this , i am trying to create alert when latency is above 300 ms

Details of my grafana query are below

I can easily create on simple conditions like errors , but dont know how can i handle derivatives like above for alerting

Any help would be appreciated, thanks in advance.

HI, thanks for writing! I *believe you're referring to these derivatives, yes? If you have the data, then you can use a Kibana Alerting rule type of Metric Threshold or Index Threshold perhaps?

Index threshold | Kibana Guide [8.4] | Elastic

Create a metrics threshold rule | Observability Guide [8.4] | Elastic

Can you elaborate if you have tried those and if they hadn't worked?

If you have the derivatives and the are only calculated at run-time it is possible a run-time field is what you'd need to create in order to make use of the data as such.

I hope this is helpful, at least to review what we know and what doesn't work. Hit us back with more details as desired.
