Hephy Monitor v2
Deis (pronounced DAY-iss) Workflow is an open source Platform as a Service (PaaS) that adds a developer-friendly layer to any Kubernetes cluster, making it easy to deploy and manage applications on your own servers.
For more information about the Deis Workflow, please visit the main project page at https://github.com/teamhephy/workflow.

About
This repository aims to contain all the necessary components for a production quality monitoring solution that runs on top of the kubernetes cluster scheduler. It provides part of the TICK stack which is produced by the influxdata team.
Current State
Currently this repo provides only 3 components (Influxdb, Telegraf, and Grafana). Telegraf is the metrics collection agent that runs using the daemon set API. For more infomation please read this.
Also provided is an Influxdb container which only runs 1 instance of the database. It also does not write any data to the host filesystem so it is not a durable system right now. For more information please read this
Lastly, Grafana is a stand alone graphing application. It natively supports Influxdb as a datasource and provides a robust engine for creating dashboards on top of timeseries data. We provide a few out of the box dashboards for monitoring Deis Workflow and Kubernetes but please feel free to use them as a starting point for creating your own dashboards.
