It is useful to think of Graphite as a big time-series database that
happens to have a UI (because that's pretty much all it is). If you were
storing your datapoints in a mysql database, would you implement your
alarming using select statements? For alarming logic that needs to look
at history, compare many metrics, or to calculate trends that might be
the way to go, but for simple threshold comparisons I would handle that
before I even store the data in the database (or at least separately).
An approach I've taken in the past is to aggregate all realtime
monitoring data in one place (well, one sharded service) for the
purposes of realtime analysis and then stream that aggregated data into
Graphite. I also have used cronjob scripts that pull a larger dataset to
do the aforementioned fancier examples.
