##Yet another gist to provide Graphite support for Dashing Pull data from Graphite and present in Dashing. Support both graph and number widget.

Quick install:

dashing install efffa657c31e244131e3

Set the graphite name and names of metrics in jobs/graphite.rb

I slice with Slic3r and have enabled verbose GCODE. I found GOCDE to move the hot end off the print at a layer change (reference eludes me right now). Wanted to share what I did with this OctoPrint plugin for my setup.

The trick is to get the retract, extrucsion reset, and Z change captured in a group so you can replay it.

My regex: (.*layer [(]{0}[)])\n(G1 X.*move.*)\n(G1 E([\d.]*) F([\d.]*)[; ]*.*unretract)

My GCODE:

Sometimes you need simple authentication in front of a REST endpoint that doesn't provide authentication. In this gist I outline how to do this with API Gateway and Lambda.

The original goal with this work was to secure a deployment of Prometheus node_exporter. I have since found the configuration for the prometheus-operator does not support setting custom headers, only Authorization. See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#%3Cscrape_config%3E

What was done:

. Create EC2 instance (sg allows 9100) . Install node_exporter on :9100 . Create Lambda function . Create API Gateway

	# get it
	docker pull mongo

	# startup a 3 node replica set
	docker run --name mongo-rs-1 -d mongo --nojournal --oplogSize 10 --replSet rs
	docker run --name mongo-rs-2 -d mongo --nojournal --oplogSize 10 --replSet rs
	docker run --name mongo-rs-3 -d mongo --nojournal --oplogSize 10 --replSet rs

	# connect to first node
	docker run -it --link mongo-rs-1:mongo1 --link mongo-rs-2:mongo2 --link mongo-rs-3:mongo3 --rm mongo /bin/bash

	# setup:
	# - one config server
	# - one mongos server
	# - 3 shard nodes (single mongod)

	# reference: https://gist.github.com/achille/82847acc0b4b94ca9f0f

	# start config server (note, override default db path to one already managed by mongo image)
	docker run --name mongo-shard-config -d mongo --nojournal --oplogSize 10 --configsvr --dbpath /data/db

	# server
	docker run --name mongo-single -d mongo --nojournal --oplogSize 10

	# client
	docker run -it --link mongo-single:mongo --rm mongo /bin/bash

	# verify you can get application list
	curl -k -X GET https://openshift.redhat.com/broker/rest/domain/lightblue/applications --user $OS_USERNAME:$OS_PASSWORD

	# delete existing app, get ID from app list above
