[jira] [Commented] (AIRFLOW-6671) Airflow sla_miss_callback
function not triggering
[ https://issues.apache.org/jira/browse/AIRFLOW-6671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17056041#comment-17056041 ]
Roster commented on AIRFLOW-6671:
---------------------------------
Can you provide example to reproduce?
You didn't mention in your explanation about the sla param in your operator.
If you can provide an example that I can run it will be easier to assist.
> Airflow sla_miss_callback function not triggering
> -------------------------------------------------
>
> Key: AIRFLOW-6671
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6671
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 1.10.2
> Reporter: Allen Lee
> Priority: Major
> Labels: sla, sla_miss_callback, slack
>
> I have been trying to get a slack message callback to trigger on SLA misses. I've noticed that:
> # sla_misses get registered succesfully in the Airflow web UI at slamiss/list/
> # *on_failure_callback* works succesfully
> However, the *sla_miss_callback* function itself will never get triggered.
> What I've tried:
> * Different combinations adding 'sla' and 'sla_miss_callback' at the default_args level, the dag level, and the task level
> * Checking logs on our scheduler and workers for SLA related messages
> [https://github.com/apache/airflow/blob/master/airflow/jobs/scheduler_job.py#L416], but we haven't seen anything
> * The slack message callback function works if called from any other
> basic task or function
>
