Question #169091 on Graphite changed:
https://answers.launchpad.net/graphite/+question/169091

    Status: Open => Answered

chrismd proposed the following answer:
The "standard" approach to this is to have create metric that has a non-
zero value whenever some event occurs (ie. events.prod.deploy_started)
and then to simply add this metric to your graphs and wrap it in a
drawAsInfinite() call. That will make every non-zero value be a straight
vertical line.

That said, there has been recent work in trunk to add proper support for
an Event datatype that is managed by django's db models rather than
hacked into the time-series storage system. If you're interested I would
suggest asking Lucio or others about this on #graphite on freenode.
Otherwise it should be documented in the next release.
