Laravel Dynamic Servers Laravel Package
spatie/laravel-dynamic-servers
Dynamically spin up and destroy servers from Laravel to handle variable queue workloads. Uses provider snapshots as templates and lets you determine server count (e.g., based on Horizon wait times) so extra workers are created automatically and removed when no longer needed.
title: Dealing with hanging servers weight: 4
Starting, stopping, and rebooting server is an asynchronous process. The package uses the self-releasing jobs VerifyServerStarted, VerifyServerStopped, VerifyServerDeleted and VerifyServerReboot to determine if such an asynchronous process completes correctly (see "How servers are managed under the hood").
In the config file you can use the mark_server_as_hanging_after_minutes key to specify how long we should wait for such processes to complete. By default, we wait for 10 minutes.
When it takes longer than 10 minutes, we'll consider the server as hanging. In the dynamic_servers table we'll update the status of the server to hanging. We'll consider that this server is not operational, and we'll not count it when determine how many servers we should start, stop or reboot when calling DynamicServers::ensure($number).
We will also fire an event ServerHangingEvent so you can take an appropriate action (sending a notification, manually deleting the server, ...). This event has two properties:
$server: the server that is hanging$previousStatus: this can bestarting,stoppingorrebooting.
