Solr Traffic Monitoring API

Analyze your Solr request traffic programmatically. Get request logs as JSON or CSV, filter by date ranges, facet by IP, path, query terms, and HTTP status codes.

Endpoint

GET https://opensolr.com/solr_manager/api/request_log

This is the same endpoint as the Request Log API, but this page focuses on practical traffic monitoring examples using facets, date filters, and aggregation. Also see the Real-Time Monitoring UI in your control panel.
