[Bug 1414137] Re: Stats page fires 63 ceilometer-api requests, runs into timeout

[James Page]

I'm not entirely sure what we can do about this; performance of the
calls is likely to be driven by the speed of the underlying hardware
supporting ceilometer and mongodb.  This does not sound like a charm
specific problem, so I'm going to push this to the Ubuntu package - it
would be useful if you can provide details as to which version of
OpenStack and Ubuntu where being used when you saw this issue.

Title:
  Stats page fires 63 ceilometer-api requests, runs into timeout

Status in horizon package in Ubuntu:
  Incomplete
Status in openstack-dashboard package in Juju Charms Collection:
  Invalid

Bug description:
  When accessing "Resources Usage Overview" / "Stats" I get timeouts for
  Period=weekly.

  I've now traced the line between web frontend and ceilometer API when
  accessing a stats page ("memory", "last week"). There are about 63
  HTTP requests going through. When running those via curl, this takes
  just a little under 4min. The data is coming back fine, but I suspect
  the web UI is not patient enough for that. Total data transferred is
  ~1.4M (uncompressed).
