Debug Perl apps and prevent crashes across your entire stack with Sentry. Send Perl errors to Sentry with the community-maintained Sentry::Raven client and resolve issues with a workflow that actually improves the debugging process.

**Documentation:** [https://docs.sentry.io/platforms/](https://docs.sentry.io/platforms/)

## Install

`Sentry::Raven` is a community-maintained client distributed via [CPAN](https://metacpan.org/pod/Sentry::Raven):

```bash
cpanm Sentry::Raven
```

Create a new instance of the SDK:

```perl
my $sentry = Sentry::Raven->new( sentry_dsn => 'https://<key>@sentry.io/<project>' );
```

See the [Perl docs](https://docs.sentry.io/platforms/) for full setup options.

## Features

### Perl Monitoring With Complete Stack Traces

See details like filename and line numbers so you never have to guess with Perl errors. Filter and group Perl exceptions intuitively to eliminate noise. Monitor errors at scale without impacting throughput in production.

### More Than Just Bug Tracking

Use issue graphs to understand the frequency, scope and impact of Perl errors so you can prioritize what needs to be fixed. Get alerts via email, SMS, or chat when bugs make it into production without disrupting your development workflow.

### Insights Delivered

Get real-time insights immediately. Install the community-maintained Sentry::Raven client from CPAN and point it at your project's DSN; setup takes just a few minutes and a couple of lines of code.

## FAQ

**What is the difference between Sentry and traditional logging?**

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they're simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail [here](/vs/logging/) and on our [blog](https://blog.sentry.io/lets-get-ready-to-monitor/).

**What  languages does Sentry support?**

Sentry supports every major  language, framework, and library. You can browse each of them [here](/platforms/).

**How much does Sentry cost?**

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our [pricing page](/pricing/).

**How does Sentry impact the performance of my app?**

Sentry doesn't impact a web site's performance.

If you look at the configuration options for when you initialize Sentry in your code, you'll see there's nothing regarding minimizing its impact on your app's performance. This is because our team of SDK engineers already developed Sentry with this in mind.

Sentry is a listener/handler for errors that asynchronously sends out the error/event to Sentry.io. This is non-blocking. The error/event only goes out if this is an error.

Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
