Analyzer ngx-req-size-by-hosts

# Name

ngx-req-size-by-hosts - Showing the top 10 hostnames order by request size

This analyzer monitors network traffic patterns in NGINX-based applications by tracking HTTP request sizes across different hostnames. It captures and aggregates request size metrics at the hostname level, generating a bar chart that displays the top 10 hostnames ranked by total request size. This analyzer helps identify which domains or virtual hosts are consuming the most bandwidth, enabling targeted optimization of network resource usage and detection of abnormal traffic patterns.
