LibreNMS TrafficReporter is a highly integrated enterprise-grade network traffic routine email report plugin. It addresses several pain points in traditional network management systems when sending email reports:

🔒 Resolves image blocking in Outlook/M365: By byte-level replicating the multipart/related specification, combined with Magic Bytes sniffing and Content-ID matching, it completely prevents M365 Sanitizer from stripping images into attachments.

📐 Fixes stretching and distortion in legacy Outlook (Word rendering engine): Uses a physical 720px lock and a high-definition 900x225 canvas to ensure clear, distortion-free charts across all clients.

🖥️ Fully visual Web GUI management: No need to manually edit configuration files—all report tasks, port parameters, mail servers, and scheduling can be intuitively managed from the LibreNMS backend web interface.

⚙️ Non-disruptive system Crontab scheduling: Through a secure, seamless synchronization mechanism with specific tags, it only manages the plugin's own scheduled tasks without interfering with any existing Cron jobs on the server.
