Modified Preorder Tree Traversal

Hierarchical data metrics that allows fast read operations on tree like structures.

Based on Left and Right fields that are set during tree traversal. When entered into node value is set to it's Left, when exiting node value is set to it's Right.

Sample implementation

#!/bin/bash

# Fix for cron incorrect paths
HOME='/root'

# Sync database1 to database2
SRC_DB='database1'
DST_DB='database2'

EXCLUDE_TABLES=(table1 table2)

#
#  contrack must also be in the users path.  Example collectd config:
