Obsolete Jobs/Queues in Metrics

• PHP Version: 8.1

Description:

Metrics is showing jobs and queues, that were already removed or renamed.

Steps To Reproduce:

1. Create and run a job

2. Rename job class and run it again

3. Define a queue, run a job through it

4. Rename queue and run a job again

In both cases old names remained in Horizon Metics panel. I hoped they will be removed after metrics.trim_snapshots exceeded, but they wasn't.

[driesvints]

This is expected. The metrics show historical data. Renaming doesn't changes the data that was snapshotted.

Is there a way to completely reset metrics?

[erickneverson]

I recognize this issue is closed, but am also curious about how to reset this particular metric. Do we need to create some sort of custom command until one is provided by the framework?

Thanks

I'm also wondering the same thing. Is there some kind of command to just completely wipe the Horizon metrics that are stored in Redis?

[trevorgehman]

Here's something I came up with to clear all Horizon metrics:

use Laravel\Horizon\Repositories\RedisMetricsRepository;

$redis = resolve(RedisMetricsRepository::class)->connection();

$redis->del('measured_jobs');
$redis->del('measured_queues');
$redis->del('last_snapshot_at');

foreach($redis->keys('snapshot:*') as $key) {
  $redis->del(str($key)->after(config('horizon.prefix')));
}

foreach($redis->keys('metrics:*') as $key) {
  $redis->del(str($key)->after(config('horizon.prefix')));
}

@driesvints Would you consider a PR for adding this command?

[driesvints]

@trevorgehman I think that could maybe be useful yeah. You could attempt a PR to see if Taylor also finds it useful, thanks.
