Grafana 9.4 introduces several enhancements to improve the querying experience with Loki, focusing on features such as query validation, improved autocomplete, query history integration, and estimated query size. The new query validation feature provides real-time feedback with a "red squiggly line" to indicate errors, allowing users to correct queries without executing them. Autocomplete has been refined to offer better suggestions, including parser type recommendations, while query history in code mode helps users build on previous work. The release also includes an estimated query size feature, offering insights into the data processing impact, and a redesigned label browser for more efficient query composition. Additionally, users can now view sample log lines related to metric queries, enhancing debugging capabilities by allowing for precise line or label filtering. Enhancements to log details include a new "Filter for this field" button and a cleanup to show only indexed or extracted labels, improving clarity in label detection. The updated line limit display provides clear information on the maximum log lines visible in results, and users are encouraged to explore these features by downloading Grafana 9.4 or using Grafana Cloud.
