## Graphite
#
# Note: If clients connecting to carbon-cache are experiencing errors such as connection refused by the daemon, a common
# reason is a shortage of file descriptors (ulimit -n).  A value of 8192 or more may be necessary depending on how many
# clients are simultaneously connecting to the carbon-cache daemon.
