Plugin Name: WhisperOutput
WhisperOutput plugins parse the “statmetric” messages generated by a StatAccumulator and write the extracted counter, timer, and gauge data out to a graphite compatible whisper database file tree structure.
Path to the base directory where the whisper file tree will be written. Absolute paths will be honored, relative paths will be calculated relative to the Heka base directory. Defaults to “whisper” (i.e. “$(BASE_DIR)/whisper”).
Default aggregation method to use for each whisper output file. Supports the following values:
Default specification for new whisper db archives. Should be a sequence of 3-tuples, where each tuple describes a time interval’s storage policy: [<offset> <# of secs per datapoint> <# of datapoints>] (see whisper docs for more info). Defaults to:
[ [0, 60, 1440], [0, 900, 8], [0, 3600, 168], [0, 43200, 1456]]
The above defines four archive sections. The first uses 60 seconds for each of 1440 data points, which equals one day of retention. The second uses 15 minutes for each of 8 data points, for two hours of retention. The third uses one hour for each of 168 data points, or 7 days of retention. Finally, the fourth uses 12 hours for each of 1456 data points, representing two years of data.
Permission mask to be applied to folders created in the whisper database file tree. Must be a string representation of an octal integer. Defaults to “700”.
