*Sending SMS on task failure - Prefect 2.0 - Plivo*

I use Plivo as SMS service, not Twilio
in Prefect 1.0 I used `'state_handlers': [o.p_state_handler]`
which sent me an SMS alert on task failure.
how can i achieve this kind of behavior in Prefect 2.0?
thanks

Hi <@U02A3LX60P9> This discourse shares how you might add a state handler for the task level in 2.0 <https://discourse.prefect.io/t/how-to-take-action-on-a-state-change-of-a-task-run-task-level-state-handler/82/10>

What does the `task_future.wait()  # block until completion` blocking?


my current handler also looks check the max retries.
`prefect.context.get("task_run_count") &gt; obj.max_retries`

and I check that task is finished and failed
`new_state.is_finished() and new_state.is_failed()`

In Prefect 2.0 I can do:
`r = task_future.get_state()`
and then check
`if r.is_final() and r.is_failed()`
but I do not see if this take into account the `retries` 
Does it ?

retries are not considered a finished or failed state. Do you want the state hander to trigger when it goes into a retrying state or just that finished or failed state?

just when failed state and when all retries did not succeeded.

Ok then that should take into account all the retries
