Karan will help Rajiv on this.

Format for the input file is as follows

WORKFLOW|JOB|DAXJOB|DAGJOB ID NOTIFICATION_CONDITION ACTION
INVOCATION JOB_IDENTIFIER INV.ID NOTIFICATION_CONDITION ACTION

ID

will have different meaning depending on the entity type

• workflow - ID is wf_uuid
• job,daxjob,dagjob - ID is the job identifier in the dag file

NOTIFICATION_CONDITION

is one of the following:

never ---> (default). Never notify of anything. This is useful to temporarily disable an existing notifications.
start ---> create a notification when the job is submitted (DAGMan state == EXECUTE).
on_error ---> after a job finishes with failure (exitcode != 0).
on_success ---> after a job finishes with success (exitcode == 0).
at_end ---> after a job finishes, regardless of exitcode.
all ---> this is like start and at_end combined.

ACTION
is what needs to happen when condition is satisfied. It will be executable + arguments.

The INVOCATION lines are only generated for clustered jobs, to specifiy the finer grained notifications for each constitutent job/invocation
