tsddrain.py

This is a simple utility for consuming data points from collectors while a TSD, HBase or HDFS is underoing maintenance. The script should be run on the same port as a TSD and accepts data in the put Telnet style. Data points are then written directly to disk in a format that can be used with the import command once HBase is back up.

Parameters

tsddrain.py <port> <directory>

Name	Data Type	Description	Default	Example
port	Integer	The TCP port to listen on		4242
directory	String	Path to a directory where data files should be written. A file is created for each client with the IP address of the client as the file name,		/opt/temptsd/

Example

./tsddrain.py 4242 /opt/temptsd/

Results

On succesfully binding to the default IPv4 address 0.0.0.0 and port it will simply print out the line below and start writing. When you're ready to resume using a TSD, simply kill the process.
