# This is an example of a Ganglia Meta Daemon configuration file # http://ganglia.sourceforge.net/ # # #------------------------------------------------------------------------------- # Setting the debug_level to 1 will keep daemon in the forground and # show only error messages. Setting this value higher than 1 will make # gmetad output debugging information and stay in the foreground. # default: 0 # debug_level 10 # #------------------------------------------------------------------------------- # 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. # # If you choose to set the polling interval to something other than the default, # note that the web frontend determines a host as down if its TN value is less # than 4 * TMAX (20sec by default). Therefore, if you set the polling interval # to something around or greater than 80sec, this will cause the frontend to # incorrectly display hosts as down even though they are not. # # 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 # data_source "my grid" 50 1.3.4.7:8655 grid.org:8651 grid-backup.org:8651 # data_source "another source" 1.3.4.7:8655 1.3.4.8 data_source "my cluster" localhost # # Round-Robin Archives # You can specify custom Round-Robin archives here (defaults are listed below) # # Old Default RRA: Keep 1 hour of metrics at 15 second resolution. 1 day at 6 minute # RRAs "RRA:AVERAGE:0.5:1:244" "RRA:AVERAGE:0.5:24:244" "RRA:AVERAGE:0.5:168:244" "RRA:AVERAGE:0.5:672:244" \ # "RRA:AVERAGE:0.5:5760:374" # New Default RRA # Keep 5856 data points at 15 second resolution assuming 15 second (default) polling.

If on, we summarize over downstream grids, and respect # authority tags. If off, we take on 2.5.0-era behavior: we do not wrap our output # in <GRID></GRID> tags, we ignore all <GRID> tags we see, and always assume # we are the "authority" on data source feeds.
