Read and send metrics from whisper files to graphite - Used to migrate to different graphite backends
Basically this little helper calculated the metric name from the filename of a whisper file and sends all timestamp/value tuples using the graphite protocol. TCP and UDP are supported. Additionally there is a NOP protocol which logs all data instead of sending it.
% ./whisper-to-graphite -h
Usage of ./whisper-to-graphite:
-basedirectory string
Base directory where whisper files are located. Used to retrieve the metric name from the filename. (default "/var/lib/graphite/whisper")
-directory string
Directory containing the whisper files you want to send to graphite again (default "/var/lib/graphite/whisper/collectd")
-host string
Hostname/IP of the graphite server (default "127.0.0.1")
-port int
graphite Port (default 2003)
-protocol string
Protocol to use to transfer graphite data (tcp/udp/nop) (default "tcp")
-workers int
Workers to run in parallel (default 5)
Assuming you don't want to use this as testcase for your IO subsystem, you might want to ensure that you don't send the data to the host you are reading it from.
