Options:

:path A function which, given an event, returns the string describing the path of that event in graphite. graphite-path-percentiles by default.

:pool-size The number of connections to keep open. Default 4.

:reconnect-interval How many seconds to wait between attempts to connect. Default 5.

:claim-timeout How many seconds to wait for a graphite connection from the pool. Default 0.1.
