BlackMaria / mod_xcat2mysql.sh

Created May 24, 2013 20:15

Configure xcat to use mysql rather than sqlite. Note if you haven't changed your mysql root passwd you should read code for more info.

	#!/bin/sh
	MANAGMENTNODE=xcat
	# passwords used in script
	# root password for mysql
	# ( if using user other than root modify below )
	SQL_ROOT_PASS=rootpw
	# The password used by xcat
	# ( you dont need to know this unless you decied to debug mysql )
	XCAT_PASS=xcat_user_passwd
	#

BlackMaria / tick_eumlator.rb

Last active December 17, 2015 17:29

A simple linear function used to emulate accumulative ticks during a day ( 6am-6am). Code outputs two values +30% and the estimated ticks water marks. This is by first ruby code :)

	#!/usr/bin/env ruby
	#
	# The idea here is, tick is almost a linear function. We really want a
	# tick_function and compare based on time of day, but this will do for now.
	#
	# We can almost determine the typical linear increase of errors
	# based on time of day. So here we assume that the linear starts
	# at 6am and increases until 6am the next day.
	#
	# NB: One flaw is that the values are less relevant before noon :}

BlackMaria / pdf_merge.sh

Created May 24, 2013 20:53

I use this all the time. d to a dir and create one pdf from all of the pdf's in that dir ( or use it in the command line, which is what I do ).

	#!/bin/sh
	pdf=*.pdf

	gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=pdfmerged.pdf $pdf

	# yeah!!!!

BlackMaria / mk_lumberjack_keys.sh

Created May 24, 2013 20:58

This is what I eventually used to generate ssl keys for lumberjack. I had made several attempts that failed and with the help of tomar ( how pointed me to a page for apache certs... ) this is what I did and it worked.

BlackMaria / logstash_testcase_output.json

Created June 5, 2013 14:14

The way I am dealing with grok failures is to create a test case from them. For others in the same boat I suggest you add this "output" to your logstash configs ( I suggest all of them ) and then you are automatically creating test cases to see what failed! NB: It has been suggested to try to pass "_grokparsefailure" tagged files passed the same…

	output {
	file {
	#gzip => true
	path => "/var/log/testcases/failed_grok_%{type}"
	tags => "_grokparsefailure"
	}
	# ....
	}

It seems that installing the latest version of Vagrant breaks the old config.

	[originally posted in 2013] It seems that installing the latest version of Vagrant breaks the old config.

	If there is something I hate, it is code that is not backward compatible AND breaks OLD configs at the same time.

	...That is to say, I installed the NEW vagrant and was told my boxes were build for OLD vagrant.
	So ( being in a rush) I reinstalled the old vagrant and that complained that I had a NEW vagrant config and refused to work.

	Meaning once you install the NEW vagrant your old config is broken so you must fix it...
	Well, this is the thing I did. Anyway, were would I be without vagrant! So thanks just the same

here is an quick example of how to install logstash and kibana to get you quick started

	#!/bin/sh
	#
	# To use logstash you need java
	# To use kibana you need nodejs
	#
	# java and nodejs are on EPEL
	#
	rpm -Uvh http://fedora.mirror.nexicom.net/epel/6/i386/epel-release-6-8.noarch.rpm
	yum -y install java-1.7.0-openjdk nodejs
