Simple bash script to wire up Grafana 2.x with InfluxDB 0.8

This Bash script exposes a few functions to create a Grafana data source, and setup the InfluxDB database behind that. It has some configuration functions in the top. It is a continuation of the Python script offered in this Grafana issue comment.

Usage

$ ./grafana-influxdb-wiring.sh name_of_database

	#include <SDL2/SDL.h>
	#include <stdio.h>
	#include <cstdlib>
	#include <ctime>

	const int WINDOW_WIDTH = 640;
	const int WINDOW_HEIGHT = 480;

	int main(int argc, char *argv[]) {
	srand(static_cast<unsigned>(time(0)));

	** This is from a modified fork of Fastbit 1.3.8, so the line numbers will be off by a little.

	Description
	-----------

	Deadlock is caused by `ibis::fileManager::getFile` (#7 below) locking the fileManager's mutex, and then the constructor
	at `ibis::fileManager::storage::storage` (#4 below) locking it in the same thread, when it realizes it needs to make
	some room in the cache first. There seem to be many similar code paths where this sort of deadlock will arise, all when
	the cache size is near or over `maxBytes`.
