• Rolling instance cycling with elasticsearch

    An easy way to cycle EC2 instances where we have an elasticsearch cluster running. As an example target we have,

    • Two instances i-11111111 and i-22222222, both running elastic search as a cluster with replicas set to 2, so that each has a replica of the others primary indices.
    • Add one to the auto-scaling group, increasing desired to 3
    • Wait for new instance i-333333 to join the cluster
  • Beats Metrics Play

    Currently I’m using the logging setup of Beaver shipping logs into an ELK stack, and metrics with collectd shipping metrics into a Graphite stack. Now that Elastic have Beats that do both logging and metrics, its worth exploring further.
