The Power of Agentless Monitoring

Before we dive into the technicalities, let’s understand the core benefits of agentless monitoring. It’s like having a silent guardian for your application, one that doesn’t require the extra resources or management overhead that traditional agents do. This means less complexity, less maintenance overhead, and better accuracy in your monitoring.

TLDR; If you have a service exposing prometheus compatible endpoint, then you can scrape those metrics directly with services like Grafana Cloud without needing any intermediate agent.

Why Supabase and Grafana Cloud

Supabase is making waves as a top pick for developers needing a backend service, thanks to its solid PostgreSQL base and ease of use.

Grafana Cloud brings a lot to the table, with its easy-to-use features like drag-and-drop dashboards, smart alerts, and even some clever machine learning tricks to help you spot and fix problems before they blow up. In short, Grafana Cloud doesn’t just make monitoring simpler; it makes it smarter, helping developers keep their apps running smoothly and their users happy.

Monitoring a Kubernetes Cluster is the need of the hour for any application following a microservices architecture. There are a bunch of solutions that one can implement to monitor their Kubernetes workload and one of them is Prometheus and Grafana. This article will help you to deploy Prometheus and Grafana in your kubernetes cluster with the help of prometheus-operator.

But before setting up these components let’s understand a bit about each of them.

Prometheus

Prometheus is a pull-based open-source monitoring and alerting tool originally built by SoundCloud. It works on a time-series database and scrapes metrics at a given interval from HTTP endpoints. After Kubernetes, Prometheus joined the Cloud Native Computing Foundation in 2016 as the second hosted project.

Alertmanager

The Alertmanager takes care of alerts sent by alerting tools such as the Prometheus server. It handles grouping, silencing, and routing them to the correct receiver integration such as email, PagerDuty, Slack, etc. It also supports the inhibition of alerts.

Grafana

Grafana is the visual representation of metrics collected by a data source which in our case happens to be Prometheus. We can create or import dashboards for grafana which will make use of promQL to visually represent metrics collected by Prometheus.
