Description Rich Jerrido 2014-07-17 20:04:50 UTC

Description of problem:

This RFE requests the ability to have pulp throttle the network speed of its synchronization tasks, as well as exposing that capability to the user via the UI/API/CLI. Optimally, this capability would be configurable either per-repo, per-product (possibly?), or globally for the satellite instance. 

Having this capability will allow the user to throttle synchronization tasks to not monopolize network bandwidth or to stay within their SLA contraints.

Comment 1 RHEL Program Management 2014-07-17 20:34:17 UTC

Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.

Comment 6 Michael Hrivnak 2015-03-05 13:42:38 UTC

Pulp offers this now. There are improvements we'd like to make to how we expose download configuration items in general, but this feature is at least available and documented. It can be set in the same places that proxy settings go, if you're familiar with that.

See "max_speed" here: https://pulp-rpm.readthedocs.org/en/latest/tech-reference/yum-plugins.html#configuration-parameters

The important thing to know is that the limit is per sync task. If you run a bunch of syncs at the same time on a bunch of different workers, each one will use up to its full limit without considering the others. We've toyed with the idea of having one global limit, but that would be very difficult to coordinate in a distributed architecture. That sort of aggregate limiting might be better done in a proxy.

Thank you, Michael.

Yes, yum's "throttle" value in /etc/yum.conf works the same way.

Should we recommend to customers who are wanting a global limit to use iptables or firewalld to limit the rate of traffic from the these IP addresses (obtained from KCS Solution 1362093)?

Comment 8 Mike McCune 2015-03-12 15:11:50 UTC

Will work to get docs for 6.2 to detail how to configure Satellite 6 to use the Pulp configiruation

Comment 13 Bryan Kearney 2016-07-08 20:19:00 UTC

Per 6.3 planning, moving out non acked bugs to the backlog

Comment 15 Rich Jerrido 2016-07-15 21:02:43 UTC

https://access.redhat.com/articles/2387381 covers how to set this up in satellite 6.1 and 6.2 until there is support in the installer (either to set the config, or to preserve it)
