Description Justin Sherrill 2017-09-14 17:29:28 UTC

I noticed this when l try to pull up the content hosts view or when I was using the foreman plugin for ansible.

In short, the @/api/v2/hosts@ call takes a very long time. With jsherril's help I've extracted some debug logs (attached). It looks like most of the SQL time is spent in lookups to rpms and errata with some more in reports.

Created from redmine issue http://projects.theforeman.org/issues/20508

Upstream bug assigned to jsherril

Comment 3 Justin Sherrill 2017-09-14 17:31:16 UTC

suggesting for 6.3, as it should help performance on the hosts api and pages.

Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/20508 has been resolved.
