Christopher added a comment. I am not sure why this is considered to be "a simple use case" since as mentioned in https://phabricator.wikimedia.org/T117735 there are at least two different requirements. Content metrics require long term (non-decaying) storage, operational metrics do not.
Whisper (Graphite's database) is not robust and has a fixed size. Even the documentation says it is not "disk space efficient". Of course, if we assume that the need is only to record a small number of data points with a low resolution, none of this matters. The added complexity of introducing backups and HDFS,, etc. to the Graphite proposition does not seem "simple". Also, the puppet module would still need to be reconfigured/modified as @Addshore tried to do, for long term retention, but this does not solve the archiving problem. There has to be a built in way to preserve and "snapshot" the database, or else it could be a real pain to restore. And, in the interim period from snapshot to restoration all measurements would be lost, unless it were on a cluster. As far as I know, Cassandra can also run on a single instance, it does not need a cluster.
