Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Section Number and Name: (nowhere so far)


Describe the issue: 
When invoking a job via REX, one can specify advanced fields like "Concurrency level" and "Life span". Setting these have nontrivial impact to the way how individual sub-tasks are managed/maintained/created. The few words hint in WebUI is insufficient to describe this.


Suggestions for improvement: 
Please provide bigger description of setting either value, what the default value is and what the default behaviour is. I do not insist on having it in our documentation, either way works well for me:

- in documentation (where is usage of REX described at all?)
- in WebUI (i.e. in pup-up help similar to "Explanation" link on "Type of query"; this might be the best, in case the description is short enough
- in KCS (that I can write down, based on input from devels)


Additional information:

Assigning to Sergei for review.

Sergei - the Host Configuration Guide already contains some text on this, but we can add some additional detail based on the description of 'Concurrency Level' and 'Time span' in the following -

The updates need to be made to the 'Executing Jobs' section.

The changes are now live on the customer portal. 

Thank you

Updating the component and doc type.
