# What to monitor. The most important section of this file. 
#
# The data_source tag specifies either a cluster or a grid to
# monitor. If we detect the source is a cluster, we will maintain a complete
# set of RRD databases for it, which can be used to create historical 
# graphs of the metrics. If the source is a grid (it comes from another gmetad),
# we will only maintain summary RRDs for it.
#
# Format: 
# data_source "my cluster" [polling interval] address1:port addreses2:port ...
# 
# The keyword 'data_source' must immediately be followed by a unique
# string which identifies the source, then an optional polling interval in 
# seconds. The source will be polled at this interval on average. 
# If the polling interval is omitted, 15sec is asssumed. 
#
# A list of machines which service the data source follows, in the 
# format ip:port, or name:port. If a port is not specified then 8649
# (the default gmond port) is assumed.
# default: There is no default value

# data_source "my cluster" 10 localhost  my.machine.edu:8649  1.2.3.5:8655

# Scalability mode. If on, we summarize over downstream grids, and respect
