Process Monitoring

webman comes with a built-in monitor process that supports two functions:

1. Monitors file updates and automatically reloads new business code (generally used during development)
2. Monitors memory usage of all processes; if a process is about to exceed the memory_limit set in php.ini, it automatically and safely restarts that process (without affecting the business)

Monitoring Configuration

Configuration for monitor in config/process.php:

global $argv;

return [
    // File update detection and automatic reload
    'monitor' => [
        'handler' => process\Monitor::class,
        'reloadable' => false,
        'constructor' => [
            // Monitor these directories
            'monitorDir' => array_merge([    // Which directories' files need to be monitored
                app_path(),
                config_path(),
                base_path() . '/process',
                base_path() . '/support',
                base_path() . '/resource',
                base_path() . '/.env',
            ], glob(base_path() . '/plugin/*/app'), glob(base_path() . '/plugin/*/config'), glob(base_path() . '/plugin/*/api')),
            // Files with these suffixes will be monitored
            'monitorExtensions' => [
                'php', 'html', 'htm', 'env'
            ],
            'options' => [
                'enable_file_monitor' => !in_array('-d', $argv) && DIRECTORY_SEPARATOR === '/', // Whether to enable file monitoring
                'enable_memory_monitor' => DIRECTORY_SEPARATOR === '/',                      // Whether to enable memory monitoring
            ]
        ]
    ]
];

monitorDir configures which directories to monitor for updates (the number of files in monitored directories should not be too large).
monitorExtensions configures which file suffixes in the monitorDir directories should be monitored.
When options.enable_file_monitor is true, file update monitoring is enabled (on Linux, file monitoring is enabled by default when running in debug mode).
When options.enable_memory_monitor is true, memory usage monitoring is enabled (memory monitoring is not supported on Windows).

Tip
On Windows, file update monitoring is only enabled when running windows.bat or php windows.php.
