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?

Building a Smart Sensor with ESP32 and DS18B20 for Data Storage

In the world of IoT, creating a smart sensor can be a fun and rewarding project. Today, we will build a temperature sensor using the ESP32 microcontroller and the DS18B20 temperature sensor. We will then explore how to send the collected data to an online service for storage and analysis. This setup is not only great for home automation but can also be adapted for industrial monitoring. Components Required ESP32 Development Board - The main microcontroller that will read temperature data and send it to the cloud.
