Prometheus Node Exporter is an essential part of any Kubernetes cluster deployment. As an environment scales, accurately monitoring nodes with each cluster becomes important to avoid high CPU, memory usage, network traffic, and disk IOPS.Prometheus works well for recording any purely numeric time series. It fits both machine-centric monitoring as well as monitoring of highly dynamic service-oriented architectures. In a world of microservices, its support for multi-dimensional data collection and querying is a particular strength.Prometheus is a popular open-source monitoring and alerting system that collects metrics from various sources and stores them in a time-series database. Prometheus uses a pull model to scrape metrics from the targets that expose an HTTP endpoint.
Do I need node exporter for Prometheus : The Node Exporter is an agent that gathers system metrics and exposes them in a format which can be ingested by Prometheus. The Node Exporter is a project that is maintained through the Prometheus project. This is a completely optional step and can be skipped if you do not wish to gather system metrics.
What is the difference between node exporter and Prometheus
Node exporter knows how to extract metrics. Those are exposed in HTTP, eg. :9201/metrics. Prometheus queries every X seconds those HTTP endpoints (node-exporter HTTTP) and stores the metrics. It also provide another HTTP for graph/console visualization/querying.
Why Grafana needs Prometheus : The combination of Prometheus and Grafana Agent gives you control over the metrics you want to report, where they come from, and where they're going.
Prometheus and the Elasticsearch stack are both used for monitoring applications. But while Prometheus is primarily meant to monitor metrics, the Elasticsearch stack or the ELK stack is mainly used to collect, store, analyze, and visualize application logs. Prometheus monitoring lets you run flexible queries and configure real-time notifications. You can use it to gain visibility into your containerized workloads, APIs, and other distributed services and applications.
Where does Prometheus get data from
A Prometheus server pulls telemetry data from somewhere else. The server uses jobs to scrape HTTP endpoints. The data from those endpoints is then pulled into the Prometheus database. A push model collects data and then pushes it to a database.The Prometheus pull model requires your Prometheus system to know all the targets. This is achieved through Prometheus Service Discovery. Prometheus Service Discovery allows you to automatically discover and monitor services in your environment.exports is part of the CommonJS specification – it defines the object that is created when a file is imported using require() . This gives developers control over which parts of a file can be accessed externally, allowing for encapsulation. Prometheus collects rich metrics and provides a powerful querying language; Grafana transforms metrics into meaningful visualizations. Both are compatible with many, if not most, data source types. In fact, it is very common for DevOps teams to run Grafana on top of Prometheus.
Is Prometheus a good monitoring tool : Prometheus has proven to be a versatile and effective monitoring tool, solving various problems for users across different industries.
What is difference between Prometheus and Grafana : Prometheus focuses on data acquisition, allowing users to select and aggregate time series data in real time. Grafana, on the other hand, focuses on data visualization. We can't really say one is better than the other, but in fact, they work best when they work together.
How is Prometheus different from Grafana
Prometheus collects rich metrics and provides a powerful querying language; Grafana transforms metrics into meaningful visualizations. Both are compatible with many, if not most, data source types. In fact, it is very common for DevOps teams to run Grafana on top of Prometheus. Prometheus + Elasticsearch
Achieve global, scalable, and secure Prometheus monitoring for containers and Kubernetes. Ship your Prometheus metrics to Elasticsearch and unify them with your logs and APM data for increased observability that's free and open.Prometheus uses service discovery to discover targets to scrape. Kubernetes clusters are equipped with labels, annotations, and a mechanism for tracking status and changes for different elements.
Can you use Prometheus without Kubernetes : Luckily, it's not only powerful and useful but also easy to set up in a home environment, with or without Kubernetes, OpenShift, containers, etc. This article shows you how to build a Prometheus container image and set up the Prometheus Node Exporter to collect data from home computers.
