ganglia

Milestone: 2

This output allows you to pull metrics from your logs and ship them to ganglia’s gmond. This is heavily based on the graphite output.

Synopsis

This is what it might look like in your config file:

output {
  ganglia {
    codec => ... # codec (optional), default: "plain"
    group => ... # string (optional), default: ""
    host => ... # string (optional), default: "localhost"
    lifetime => ... # number (optional), default: 300
    max_interval => ... # number (optional), default: 60
    metric => ... # string (required)
    metric_type => ... # string, one of ["string", "int8", "uint8", "int16", "uint16", "int32", "uint32", "float", "double"] (optional), default: "uint8"
    port => ... # number (optional), default: 8649
    slope => ... # string, one of ["zero", "positive", "negative", "both", "unspecified"] (optional), default: "both"
    units => ... # string (optional), default: ""
    value => ... # string (required)
    workers => ... # number (optional), default: 1
  }
}

• Default value is "uint8"

The type of value for this metric.

port
