Announcing Sentry.jl: A minimal SDK for Sentry in julia

Presage is happy to open-source Sentry.jl, a small package designed to make interfacing with sentry easier when building web applications with julia. Sentry.jl builds on the work done by SentryIntegration.jl, with updates to the code to allow installation in modern versions of julia without dependencies on unregistered packages.

Sentry.jl is a set of utilities for capturing data about an exceptional state in an application. Given this data, it then builds and sends a JSON payload to the Sentry server.

To use Sentry.jl, you will need an account on sentry.io. Once you have a DSN assigned to your project, you can initialize the package using the Sentry.init() function.

Sentry.init("https://0000000000.ingest.sentry.io/0000000")

The core functionality is in the capture_exception and capture_message functions, which are intended to be used at a high level in your application. When these functions are called after Sentry.jl is initialized, they will capture, package, and send the error object to Sentry. As a basic example:

try
    core_loop()
catch exc
    capture_exception(exc)
end

Tags can be set to make classification and sorting of errors easier:

Sentry.set_tag("customer", customer)
Sentry.set_tag("release", string(VERSION))
Sentry.set_tag("environment", get(ENV, "RUN_ENV", "unset"))

Presage uses a julia-based server to quickly and efficiently process questionnaire results and provide near-realtime feedback to our clients about their employees. Sentry.jl is an important part of monitoring the health of this server and will continue to be developed into a full-featured SDK. You can contribute to or just keep up with our progress on github at the Sentry.jl repository.
