When you put the semaphore in red status, all the cron jobs are suspended until you programmatically call the resume method or after the timeout limit.

How to use

Just inject the following manager:

\Websolute\CronSemaphore\Api\CronSempahoreManagerInterface $cronSempahoreManager

The use the suspend(int $forSeconds = 300) command to put the semaphore in red status:

$this->cronSempahoreManager->suspend();
$this->cronSempahoreManager->suspend(600); // Pass an integer that represents the timeout at 600 seconds

The use the resume() command to put the semaphore in green status:

$this->cronSempahoreManager->resume();
