# mesos-cloudwatch-autoscale

simple container which designed to run inside metronome (or other cron like mesos framework) which takes the current CPU\mem\HD percentage and exports it to cloudwatch every X minutes in order to allow that metrics to be used to autoscale the mesos cluster workers according to current use percentage.

required envs:

* AWS_ACCESS_KEY_ID (or IAM role)

* AWS_SECRET_ACCESS_KEY (or IAM role)

* AWS_DEFAULT_REGION (example: us-east-1)

* MESOS_URL (example: leader.mesos for use inside mesos)

* MESOS_PORT (example: 5050)

* METRICS_PREFIX (example: mesos_)

* METRICS_NAMESPCE (example: mesos/)

the script will then create 3 new cloudwatch metrics named:

* metrics_prefix_mem_percentage

* metrics_prefix_cpu_percentage

* metrics_prefix_hd_percentage

example metronome job config:
