I have created a promotion in Smart Target and published it and I can see promotion file is deployed in fredhopper indexer instance . But it is not getting processed by STkettle job immediately. If I run manually it is getting processed.

Here is my few question,

1.How can I know what is schedule interval and whether ST kettle job is running or not.
2. Does ST kettle job start to run automatically when we start fredhopper instance through command prompt.

3.will I be able to see the promotion immediately in preview mode of indexer server and query server?
