Hello Ivan, or anyone else affected,

Accepted collectd into trusty-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/collectd/5.4.0-3ubuntu2.1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

The package is in the upload queue. You can see it at
https://launchpad.net/ubuntu/trusty/+queue?queue_state=1

There should be a post in this thread when it is released into trusty-
proposed. Then the fix will need to be verified so that it can move into
trusty-updates.

I uploaded this to trusty's queue, thanks!

I'm not sure if the SRU team will like the description though - if I were you 
I'd update it to clearly state the required information.

[Bug 1372750] Re: A patch for collecting swap utilization in openvz

[Marius Gedminas]

This is the first time I'm proposing an SRU.  I've updated the
description -- what should I do next?  Unassign myself?  Subscribe
ubuntu-sponsors again?

** Description changed:

+ [Impact]
+ 
+ * Any users of collectd that run Ubuntu 14.04 LTS in an OpenVZ container
+ will no longer be able to track swap usage.  This is a regression from
+ Ubuntu 12.04 LTS
+ 
+ [Test Case]
+ 
+ * Get yourself an OpenVC container with some enabled swap space
+ 
+ * sudo apt-get install collectd
+ 
+ * Let it run for a few minutes
+ 
+ * ls /var/lib/collectd/rrd/*/swap/
+ 
+ You should see four files there: swap-free.rrd  swap_io-in.rrd  swap_io-
+ out.rrd  swap-used.rrd
+ 
+ If you see only two (swap_io-in.rrd  swap_io-out.rrd), then you're
+ affected by this bug
+ 
+ [Regression Potential]
+ 
+ * I see no way this could end badly ;)
+ 
+ * I've backported the upstream patch to a package in my PPA (ppa:pov),
+ and have been running it since November 2015.
+ 
+ [Other Info]
+ 
+ * The upstream bug is https://github.com/collectd/collectd/issues/733.
+ It has a fix in master for the upcoming 5.5.0 release at
+ 
https://github.com/collectd/collectd/commit/8b618e1fb63ca5f8c741e95651bc41cf6e454588,
+ and a smaller fix suitable for backporting for older versions (since
+ 5.3.x) at
+ 
https://github.com/collectd/collectd/commit/1a146775d42a15202cba4e19c0fcda465705bcb8.
+ 
+ 
+ [Original Bug Report]
+ 
  In collectd-5.4.0-3ubuntu2 there is a bug that prevents collectd from
  collecting information about swap utilization.
  
  Here is a corresponding issue on github:
  https://github.com/collectd/collectd/issues/733
  
  Also the developer provided the minimalistic patch that fixes the issue
  and would be applicable for 5.4.0:
  
https://github.com/collectd/collectd/commit/1a146775d42a15202cba4e19c0fcda465705bcb8

Thank you for your work, the change looks good but for a SRU you need
description of the impact/test case/regression potential (see
https://wiki.ubuntu.com/StableReleaseUpdates).

Also the issue should be fixed in the current serie before being
backported (either by merging the new version from debian or by applying
a similar patch to the current source)

Upstream fix went into 5.5.0, according to git tags on
https://github.com/collectd/collectd/commit/8b618e1fb63ca5f8c741e95651bc41cf6e454588.

Debian testing has collectd 5.5.0.

Ubuntu xenial is still on 5.4.1, so is, in theory, affected by this bug.
(I don't have a spare OpenVZ container to test -- I'm renting these
containers as cheap VPSes from a local provider.)

corrected debdiff) fixes this problem for me.

https://launchpad.net/~pov/+archive/ubuntu/ppa/+packages?field.name_filter=collectd_filter=published_filter=

Now, before this can be SRUd to trusty, it needs to be fixed in xenial.
