Metrics Explore is a feature within Logz.io designed for in-depth analysis of Prometheus metrics, offering functionalities akin to Kibana Discover, such as easy querying and metadata exploration. It allows users to navigate metrics efficiently through organized lists and dropdown selections, and includes features like query autocomplete to simplify metric identification. Additionally, it supports distributed tracing with Logz.io and Jaeger, providing a comprehensive view of metrics across various services. The platform emphasizes the importance of metadata labels for metric segmentation and offers optimization suggestions for metric displays. A notable feature is the split screen, which enables simultaneous viewing of metrics and logs or comparisons of different data sources, enhancing the user's ability to analyze and contrast performance metrics effectively. Logz.io continues to develop its Metrics UI to leverage the capabilities of Prometheus-as-a-Service, with updates available through their blog subscription.
