The easiest way to install InfluxDB & Grafana and configure them to work with Collectd is through using pre-built InfluxDB & Grafana containers. Manual installation steps are detailed further below.
Overview of Pre-built InfluxDB & Grafana Containers
The barometer-influxdb image is based on the influxdb:1.3.7 image from the influxdb dockerhub. To view detils on the base image please visit https://hub.docker.com/_/influxdb/ Page includes details of exposed ports and configurable enviromental variables of the base image.
The barometer-grafana image is based on grafana:4.6.3 image from the grafana dockerhub. To view details on the base image please visit https://hub.docker.com/r/grafana/grafana/ Page includes details on exposed ports and configurable enviromental variables of the base image.
The barometer-grafana image includes pre-configured source and dashboards to display statistics exposed by the barometer-collectd image. The default datasource is an influxdb database running on localhost but the address of the influxdb server can be modified when launching the image by setting the environmental variables influxdb_host to IP or hostname of host on which influxdb server is running.
Additional dashboards can be added to barometer-grafana by mapping a volume to /opt/grafana/dashboards. Incase where a folder is mounted to this volume only files included in this folder will be visible inside barometer-grafana. To ensure all default files are also loaded please ensure they are included in volume folder been mounted.
Installation & Configuration of Pre-built InfluxDB & Grafana Containers
To avoid duplication, detailed up to date steps are provided in the Barometer Docker User Guide. The steps mentioned have been verified for Ubuntu 18.04, 16.04 & Centos 7.5.
Steps related to scalable deployment of Collectd, InfluxDB & Grafana across multiple nodes is also documented.
Manual Installation of InfluxDB & Grafana
I would recommend installing collectd, influx and grafana on a second server to let you capture and graph the displays over time…
Note: you you only need collectd on this second server – for the types definition, so you could copy this from any server that has collectd installed
ON Note: The following steps are recommended for Ubuntu 16.04
On the DUT
So on the DUT you will need to configure collectd to send the metrics it collects to the server running influx + grafana using the network plugin:
<Plugin "network">
Server "influx server ip" "25826"
</Plugin>
On the Influx/Grafana server:
