10. Prometheus

Prometheus dashboard

Prometheus is 100% open source and community-driven, meaning it’s completely free to use and was inspired by Google’s Borgmon monitoring system.

Why do we recommend it?

Prometheus emerges as a powerhouse in the realm of Python monitoring, and here’s the kicker—it’s all about that open-source allure. Unleashing a 100% community-driven vibe, this monitoring marvel comes with a price tag of zero, inspired by the legendary Google’s Borgmon system. Prometheus doesn’t just stop at the surface; it delves into multiple layers of monitoring nirvana—internally, as a service, through server libraries, and even ventures into the terrain of business logic insights. But here’s the catch: Prometheus speaks its own language, the PromQL, a functional query powerhouse that opens the gateway to real-time data queries. The expressive queries can flex their muscles in graph format, opt for a spreadsheet view, or take the express lane to elsewhere via HTTP API integration.

Monitoring can be done on multiple layers including internally, as a service, through server libraries, and provide business logic insights. Prometheus uses a functional query language called PromQL that allows for data to be queried in real-time. Expressions can be displayed in graph format, broken down into spreadsheet view, or sent elsewhere for processing through the HTTP API integration.

To graph out your data you’ll need to utilize another tool such as Grafana. Once installed you can set Prometheus as a data source to start pulling in metrics live. While open-source platforms like Grafana have a collection of shared dashboards, this is still going to take you time to set up, test, and implement.

Alerting rules are defined on conditions and are based on the Prometheus expression language. While there are alerting templates, any type of customization or changes is going to be a bit cumbersome to manually integrate.

These are not out of the box solutions and require some knowledge of the platform which would take time. This is fairly common with open source platforms. If you have the time to tinker with Prometheus and don’t mind relying on the open-source community for help, this is a solid free alternative for Python monitoring.

Who is it recommended for?

Prometheus is the choice for those who crave the freedom of open-source monitoring without breaking the bank. Its allure lies in catering to a diverse audience, whether you’re an internal scrutineer, a service aficionado, or a logic insights enthusiast. But, here’s the twist—the road to graphing utopia demands a companion, and Grafana is the sidekick of choice. This power duo’s synergy lets you visualize metrics in real-time. While platforms like Grafana flaunt an array of shared dashboards, remember, you’re in for some DIY action—setup, testing, and implementation will demand your attention. Brace yourself for Prometheus’ expressive Alerting rules, rooted in its expression language. Just a heads up—customizing might be a tad tricky, and the open-source community might become your confidante.
