Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh

A grok pattern for Rails 3.2 logs for use with logstash. Assumes that you have a multiline filter to combine Rails logs into one line and only one worker is logging to a file (c.f. https://gist.github.com/mudge/5063930).
multiline {
tags => ["rails"]
pattern => "^Started"
negate => true
what => "previous"
}

Elasticsearch Tuning Plan

Next Steps

  • Measure time spend on index, flush, refresh, merge, query, etc. (TD - done)
  • Take hot threads snapshots under read+write, read-only, write-only (TD - done)
  • Adjust refresh time to 10s (from 1s) and see how load changes (TD)
  • Measure time of a rolling restart doing disable_flush and disable_recovery (TD)
  • Specify routing on query -- make it choose same node for each shard each time (MD)
  • GC new generation size (TD)
  • Warmers
  • measure before/after of client query time with and without warmers (MD)
