Understanding How Remote Write Works in Prometheus

Prometheus, a leading open-source monitoring and alerting toolkit, is renowned for its robust capabilities in collecting and querying time-series data. However, as organizations scale, the need to store and analyze data beyond the local Prometheus instance becomes crucial. This is where Prometheus’s remote write feature comes into play, enabling the seamless transmission of time-series data to external storage systems for long-term storage, advanced analytics, or centralized monitoring. What is Remote Write?

Using Prometheus Remote Write API: A Practical Example

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. With its powerful querying language and data model, it has become a staple in the DevOps and SRE communities. One of the key features of Prometheus is its Remote Write API, which allows for the efficient forwarding of time series data to external systems. This article explores how to set up two Prometheus instances, where one instance sends its metrics to another using the Remote Write functionality.
