We need 3 things from our monitoring systems: Log aggregation and analysis tools for (deep-dive info) Data visualization tools (at-a-glace information, data correlation/causation, pattern identification, easier anomaly detection) non-simple error reporting (To let us know when things are actually going wrong. e.g. rollups, multi-variable alerts, alerts that include more data than 'I passed a threshold')

If I were starting from scratch, this is the architecture I'd build for monitoring.

Logstash -> Reimann and/or Flapjack-> (dataviz) Statsd -> Graphite -> Tasseo & Descarte

One day of Go

One of my ongoing resolutions is to learn a new programming language every year. I've been looking at Go for a while and I thought it would be fun to use the 'holiday' today to really get cranking. I recorded some random impressions as I was chugging along...

When learning a language, I'm one of those people that can't simply read documentation and contrived code examples with any usable level of recall -- I need to internalize it by writing code to solve a legitimate problem. So, I decided to write a little library, a parser for the Linux /proc filesystem. There aren't very many good ones that I've found for Go (and I am thinking of some projects I may want to use it for in the future).

Steps taken:

1. Read a bit of code

username = 'testuser'

aws_credentials = { 
  :aws_access_key_id => 'YOUR-ACCESS-KEY-ID',

# First upload a public key to use for SSH'ing to instance.  Use "ssh-keygen" to generate.
fp = open(os.path.expanduser('~/.ssh/mykey.pub'))
material = fp.read()
