# Silverstripe errors, logs, and breadcrumbs

## Errors

The framework logger receives a Talaria Monolog handler (Monolog 3 on Silverstripe 5 and 6, Monolog 1/2 on Silverstripe 4). An error logged through `Injector::inst()->get(LoggerInterface::class)` is captured. Uncaught exceptions that Silverstripe logs take the same path.

Handled failures can call the core API:

```php
use Talaria\Talaria;

try {
    $this->charge();
} catch (Throwable $e) {
    Talaria::captureException($e, [
        'tags' => ['area' => 'billing'],
    ]);
    throw $e;
}
```

## Logs

Anything you log at warning or above is sent. `minLevel` defaults to `warning`.

```php
use Psr\Log\LoggerInterface;
use SilverStripe\Core\Injector\Injector;

Injector::inst()->get(LoggerInterface::class)
    ->warning('Payment method missing');
```

Named presets live under `Talaria\SilverStripe\Config.loggers` in YAML. `Talaria::logger('businessDirectory')` uses that preset's level and tags.

## Breadcrumbs

Core `Talaria::addBreadcrumb` works. HTTP requests and queued jobs add their own crumbs and attach the trail to the next error.

```php
Talaria::addBreadcrumb([
    'type' => 'default',
    'category' => 'checkout',
    'message' => 'Charge started',
    'level' => 'info',
]);
```

## Identity and context

The logged-in Member id is `userId` on PHP events and on the injected browser init. Per-request tags include `ajax`, `ss_env`, and `host`. The process also sends `platform=php` and `runtime=silverstripe`. Set `release` with `TALARIA_RELEASE`. Optional YAML `service` and `tags` merge into init tags.

Fingerprints are computed on the server.
