Unexpected low load alert not working as expected

[DamianG]

We have "Unexpected low load" alerts and we think alerting is not working as expected because some alerts are raised when de load of a request is not reaching the thresholds set. E.g:

• Settings:

Does this configuration means that an alert will be triggered when traffic decreases 90% (or more) than expected during 15 minutes? This means, an alert will be triggered if there is  only 10% (or lower) than expected?

• Example: an alert was raised when the is traffic is not zero and with no significant changes:

If we do a comparison:

   - 2 hours before:

   - 1 day before

    - 1 week before:

The key here is that 3 weeks ago I changed the settings from 80% to 90% and now I'm getting more alerts than before.

Is this behavior correct?

Thank you.
