To achieve this, you can use Grafana in combination with other tools such as Prometheus for uptime monitoring and data collection, and exporters or plugins for collecting visitor stats from sources like Matomo or other analytics platforms.

Here's a general outline of how you could set up this monitoring solution:

Install and configure Grafana: Start by setting up Grafana on your server and configuring it according to your needs. Grafana provides extensive documentation to guide you through the installation and configuration process.

Set up Prometheus for uptime monitoring: Prometheus is a popular monitoring and alerting tool. You can use it to scrape data from your websites and monitor their availability. Prometheus has exporters available for various types of monitoring, including ICMP ping and HTTPS checks. These exporters can send metrics to Prometheus, which Grafana can then visualize.

Integrate visitor stats: If Matomo is your preferred tool for visitor stats, you can explore available Matomo exporters or plugins that can export the relevant data into Prometheus. Once the data is in Prometheus, you can use Grafana to create dashboards that display both uptime and visitor stats side by side.

By combining Prometheus, Grafana, and appropriate exporters/plugins, you can achieve a comprehensive monitoring solution that covers both uptime and visitor statistics. Remember to review the documentation and support resources for each tool to ensure smooth integration and customization based on your specific requirements.

It's worth noting that the setup and configuration of these tools may require technical expertise. If you're not familiar with server administration or monitoring tools, you may want to consider consulting with a knowledgeable professional or seeking assistance from the respective communities of these tools.
