overlord

This project contains 3 modules

• overlord-client -> which has API and internal implementation of the overlord library
• overlord-client-service -> this is a sample service logging the metrics to overlord library
  --- This module has a telegraf.conf file which reads the metrics aggregates them and sends to the influxDB
  --- It has a run.sh which has the required commands to run the client-service and the telegraf plugin
  Note: External dependencies has to be installed seperately.
  
• influx.tmpl has the code to create the influxdb with the right buckets, retention policies, tasks and dashboards
  --- there are multiple buckets for different metrics aggregation window. i.e. one for raw_logs, 1min, 5min, etc
  --- tasks has downsampled tasks which read from raw logs and downsample to appropriate buckets
