Install and Configure collect

You will need to install the following for this next section.

apt-get install -y collectd

Once installed you now need to configure collectd to utilize the proxy we installed

vi /etc/collectd/collectd.conf

Uncomment and update the lines:

LoadPlugin network

<Plugin network>
        Server "10.10.10.10" "8096"
</Plugin>

Where we have 10.10.10.10 you’ll want to replace with your container’s private IP address.

Verify

You can use tcpdump to ensure packets are traveling over UDP to your container.

tcpdump -i eth1 -p -n -s 1500 udp

listening on eth1, link-type EN10MB (Ethernet), capture size 1500 bytes
23:59:07.014256 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 02:01:81:99:60:fa, length 300
23:59:13.104494 IP 10.10.10.11.42509 > 10.10.10.10.8096: UDP, length 1331
23:59:13.104773 IP 10.10.10.11.42509 > 10.10.10.10.8096: UDP, length 1332

You should also be able to query InfluxDB to see your metrics:

select * from "ubuntu/cpu-0/cpu-idle"

You’re next steps are to now setup your Grafana dashboard in the way you’d like.
