Netdata
Netdata is a highly optimized open source monitoring agent you install on all your systems and containers. Netdata provides unparalleled insights, in real-time, of everything happening on the systems it runs in (including web servers, databases, applications), using highly interactive web dashboards.
Netdata can run autonomously, without any third party components, or it can be integrated to existing monitoring tool chains (Prometheus, Graphite, OpenTSDB, Kafka, Grafana, etc). Netdata is fast* and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices) without disrupting their core function.*
Netdata is free, open-source software, and can be found at https://github.com/netdata and

Creating an App using the Control Panel
Click the Deploy to DigitalOcean button to install a Kubernetes 1-Click Application. If you aren’t logged in, this link will prompt you to log in with your DigitalOcean account.
Creating an App using the API
In addition to creating Netdata using the control panel, you can also use the DigitalOcean API. As an example, to create a 3 node DigitalOcean Kubernetes cluster made up of Basic Droplets in the SFO2 region, you can use the following doctl command. You need to authenticate with doctl with your API access token) and replace the $CLUSTER_NAME variable with the chosen name for your cluster in the command below.
doctl kubernetes clusters create --size s-4vcpu-8gb $CLUSTER_NAME --1-clicks netdata
Getting Started After Deploying Netdata
After you have downloaded your kube config file, and are able to successfully connect to your DigitalOcean Kubernetes cluster (see https://cloud.digitalocean.com/kubernetes/clusters/ if you haven’t connected to your cluster) follow the instructions below to start using netdata.
Port-forwarding to the Netdata dashboard
You can quickly forward a local port to the Netdata dashboard in your cluster with the following command
kubectl -n netdata port-forward svc/netdata 19999
Then visit your Netdata dashboard at http://localhost:19999 or http://127.0.0.1:19999 and explore the Netdata pod dashboard metrics along with the dashboard metrics and any alarms you may wish to configure for each node in your cluster.
