The influxdb open source software is a good tool to use to collect metrics from sensors. It is easy to setup and easy to work with (see the VSCP wiki) and querying with flux makes it a very potent tool. There is a build in diagnostic and presentat interface, but it is equally simple to display data (as we show in the demos) from influxdb on any custom web page.
You can also use Grafana to make nice graphics for your influxdb collected data and I will add some samples for it to later.
You find the demo pages at https://demo.vscp.org as always.
