What is the recommended monitoring architecture with Prometheus on Liquid Web?
There isn't a specific recommended monitoring architecture for Prometheus on Liquid Web, as the architecture largely depends on the specific needs and preferences of your application and infrastructure. However, here are some general guidelines to help you set up a Prometheus monitoring architecture:
- Prometheus Server: Start by setting up a dedicated Prometheus server that collects metrics from different targets. You can install Prometheus on a separate server or use an existing server, depending on the scale and requirements of your infrastructure.
- Exporters: Deploy exporters on your infrastructure to collect metrics from various services and applications. Prometheus exporters act as bridges between Prometheus and different types of software. They help in extracting the required metrics and making them available for Prometheus to scrape.
- Node Exporter: The Node Exporter is a common exporter used to monitor system-level metrics, such as CPU, memory, disk usage, and network statistics. Install it on every server that you want to monitor.
- Service-Specific Exporters: Depending on your application stack, you may need to install additional exporters to monitor specific services or databases. For example, for monitoring a MySQL database, you can use the MySQL Exporter.
- Alerting: Configure alert rules in Prometheus to trigger notifications when specific conditions are met. Prometheus allows you to define and manage alerting rules based on the collected metrics.
- Visualization and Querying: Prometheus has a built-in expression browser called Prometheus Query Language (PromQL). However, for more advanced visualization and querying capabilities, you can integrate Prometheus with Grafana. Grafana can be used to create dashboards, visualize metrics, and set up alerts based on Prometheus data.
Remember, the architecture should be scalable and adaptable based on your specific needs. Monitor and adjust the setup as your infrastructure evolves over time. It's recommended to consult the official Prometheus documentation and seek professional guidance when setting up Prometheus in a production environment.
How to scale Prometheus horizontally on Liquid Web?
To horizontally scale Prometheus on Liquid Web, you can follow these steps:
- Provision additional Prometheus servers: Start by adding more Prometheus servers to your environment. You can do this by spinning up new instances or virtual machines on Liquid Web's infrastructure.
- Set up a load balancer: Deploy a load balancer to distribute incoming traffic across multiple Prometheus servers. Liquid Web offers load balancer services or you can use your preferred load balancing solution.

- Install Prometheus: If Prometheus is not already installed on your Liquid Web server, you can follow the installation guide provided by Prometheus.
- Configure Prometheus: Once Prometheus is installed, you need to configure it to collect and store the custom metrics. Locate the prometheus.yml configuration file, usually found in the /etc/prometheus/ directory, and open it with a text editor.
- Define the custom metric: Inside the scrape_configs section of the prometheus.yml file, add a new job to scrape the metrics endpoint of your application. You need to specify the target to scrape, such as the IP address or domain name of your application. For example: - job_name: my_custom_app static_configs: - targets: ['localhost:8080'] # Replace with your application's IP and port
- Restart Prometheus: Save the changes to the prometheus.yml file and restart the Prometheus service for the changes to take effect. Use the appropriate command based on your operating system to restart the Prometheus service.
- Instrument your application: In your application's code, you need to incorporate a Prometheus client library to expose the custom metrics. The choice of client library will depend on the programming language/framework your application uses. For example, if you are using Node.js and Express, you can use the prom-client library to instrument your endpoints and expose custom metrics like counters or gauges.
- Export the metrics: Once your application is instrumented, it will expose the custom metrics on an endpoint defined in your code. Prometheus will scrape this endpoint to collect the metrics data. To check if the metrics are being successfully exported, you can navigate to http://:9090/targets to see if the target for your custom metrics job is being successfully scraped.
- Query custom metrics: With the custom metrics scraped and stored by Prometheus, you can then use PromQL (Prometheus Query Language) to query and visualize the metrics in the Prometheus built-in web UI or integrate with other monitoring tools like Grafana.
By following these steps, you should be able to create custom metrics in Prometheus on Liquid Web and monitor and analyze them for your application's needs.
