This tool is designed for administrators and developers working with Varnish Cache. It specifically addresses the 'Vhost unknown' error, a common issue where Varnish cannot match an incoming request to a defined virtual host (vhost), leading to failed requests and site downtime.

Error Detection: Automatically scans your Varnish configuration and logs to pinpoint instances of the 'Vhost unknown' error. Configuration Analysis: Checks your vhost definitions against incoming request patterns to identify mismatches or missing entries. Resolution Guidance: Provides clear, actionable steps to correct the configuration, such as adding missing vhosts or adjusting routing rules. Proactive Monitoring: Can be integrated into monitoring workflows to alert teams before the error impacts live traffic. Log Parsing: Efficiently processes Varnish access logs to trace the origin of requests that trigger the error, aiding in root cause analysis.
