9e38cca Enforce nanosecond precision on fields containing enqueue-times (#95)

Demo deployment scripts

This "release" contains two script files to deploy Cherami onto AWS EC2 machines. These scripts are for illustration only, but it can be useful to deploy a small cluster. Note that it also deploys Cassandra and Grafana stack in single-box mode, which may or may not suit your need.

To use the scripts, you need to retrieve deploy_cherami.sh. It can be run from anywhere, as long as the operator has right ssh access to the EC2 deployment target. Before you run the script, you need to edit the file to fill in necessary host IP information:

CASSANDRA_EXTERNAL: Public IP address of the Cassandra host
CASSANDRA_INTERNAL: Private IP address of the Cassandra host
METRICS_EXTERNAL: Public IP address of the Grafana host
METRICS_INTERNAL: Private IP address of the Grafana host
CHERAMI_EXTERNAL: List of Public IP addresses of the Cherami hosts
CHERAMI_INTERNAL: List of Private IP addresses of the Cherami hosts

genconf.pl is a scripts to generate base.yaml config file. This script prints a base.yaml file based on input parameters specified in the environment variables for cluster deployment. CASSANDRA is Cassandra IPs (comma-separated), STATSD is StatsD host IP, IP is the listen IP address, UUID is a UUID for this host, and HOSTS is a comma-separated IP address of other Cherami hosts. Script assumes Cherami data will be stored at /var/cherami/data.
