## GET /api/v2/shared-hosting/{accountId}/diagnostics/redis

**Inspect Redis socket metadata**

Inspect the fixed account Redis socket file and PHP Selector configuration through cPanel Fileman. No PING, command execution or Redis connection is performed. Socket presence is not service availability; connectionTested is false and ping is null. Use cPanel > HostUp Features > Redis Socket to check actual service state. This read cannot start/stop Redis or read cache values.
