Netdata master with graphite backend running on Centos 7 / RHEL7

Install Netdata master

To install Netdata run the following on the master node

bash <(curl -Ss https://my-netdata.io/kickstart.sh) all

Create an API key uuidgen

Edit your netdata stream.conf and change the Master section

vim /etc/netdata/stream.conf

Replace the API with your API key and enable the master

[a38ff2b5-d132-4bbb-9e7c-0737db51a07d]
enabled = yes
default history = 3600

Now start your Netdata master node systemctl restart netdata

Installing Netdata on the client node

Run the following command on your client, this will install the static prebuilt version of Netdata

bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)

After installing Netdata successfully, change the stream config under the slave section

vim /opt/netdata/etc/netdata/stream.conf

[stream]
enabled=yes
destination= FQDN/IP of your Netdata master
api key = c76a2d2f-8921-49c0-8ac3-aa3d728229a5

This is optional

We don't need to keep the collected data in the slaves databases, so we disable them

vim /opt/netdata/etc/netdata/netdata.conf

[global]
# disable the local database
    memory mode = none

[health]
# disable health checks
enabled = no

After configuration is done, start your Netdata client

systemctl restart netdata

Archiving collected data to Graphite backend

The above setup will only keep data for 1 hour, we need to be able to look back. We want to archive the collected data from the master node to timeseries database like Graphite. We can then create dashboards with Grafana.

Install Graphite - Grafana with Docker

Clone this repo from kamon-io, it will install Docker container with Graphite and Grafana. You will need to have Docker, make and docker-compose installed

git clone https://github.com/kamon-io/docker-grafana-graphite.git
docker-grafana-graphite
make up
docker ps

2876bd29472b        kamon/grafana_graphite    "/usr/bin/supervisord"   27 minutes ago      Up 27 minutes

dashboard

You can connect to your Graphite web interface on port 81 and Grafana UI on port 80. Graphite will be listening for metrics on tcp port 2003. We will not use the Statsd port.

Setting up the backend on Netdata master

On you Netdata master node, open up the netdata.conf

vim /etc/netdata/netdata.conf

Add this section:

     [backend]
     enabled = yes
     data source = average
     type = graphite
     destination = FQDN of your graphite server:2003
     prefix = netdata
     hostname = netdata-master
     update every = 10
     buffer on failures = 10
     timeout ms = 20000
     send names instead of ids = yes
     send charts matching = *

Now restart your Netdata master node systemctl restart netdata

Now connect to your graphite server on port 81, you should see new folder named netdata.
