It resets a query counter at the start of the request and increments it every time a query is executed. +At the end of the request, if the total number of queries exceeds the configured threshold, a warning is logged. +- For Artisan commands, the package listens to the CommandStarting and CommandFinished events. +It resets the counter before the command runs and checks the final count after the command completes. +- For CLI contexts (other non-command CLI scripts), you can manually integrate by resetting and checking counts in your own script logic. + +### Configuration +All configuration options are defined in the querymonitor.php config file under the total_queries key: +```php +'total_queries' => [ + + /* + * Whether to enable total query monitoring. + */ + 'attiva' => env('QUERYMONITOR_TOTAL_QUERIES_ATTIVA', true), + + /* + * Maximum allowed total queries per request/command. + * If this threshold is exceeded, a warning is logged. + */ + 'maxTotalQueries' => env('QUERYMONITOR_MAX_TOTAL_QUERIES', 500), + + /* + * A regex to filter which contexts to monitor. + * - For HTTP requests, this regex will be matched against the full URL (including query string). + * - For Artisan commands, it will be matched against the command name. + * - For CLI contexts, it can be matched against the script name. + * If unset or empty, all contexts are monitored. + * Example: '^/api/.*$' to monitor only requests under /api/ + */ + 'traceRegEx' => env('QUERYMONITOR_TOTAL_QUERIES_REGEX', null), +], +``` + +### Enabling Total Query Monitoring for HTTP Requests +To track the total number of queries for HTTP requests, the package provides a `TrackTotalQueriesMiddleware`. +This middleware must be added as the first middleware in the global middleware stack. + +By doing so, it can: + +- **Set up tracking before any other middleware or controllers run**, ensuring that all queries executed during the request lifecycle are counted. +- **Perform a final check after the response is generated**, running last in the outbound cycle, so that it includes queries made by all subsequent middleware, controllers, and operations performed downstream. + +**How to add it:** + +In your `app/Http/Kernel.php`, ensure that `\Padosoft\QueryMonitor\Middleware\TrackTotalQueriesMiddleware::class` appears at the top of the `$middleware` array: + +```php +protected $middleware = [ + \Padosoft\QueryMonitor\Middleware\TrackTotalQueriesMiddleware::class, + // ... other global middleware ... + ]; +``` + +By placing the TrackTotalQueriesMiddleware first, you guarantee comprehensive coverage of every query executed during the request lifecycle. +Once the request is fully processed, the middleware checks the total query count and logs a warning if it exceeds the configured threshold. + + +### Examples of Logs +- **1.
