Sidekiq: Dead jobs callback/notification

[jvenezia]

Hi,

I would like to get notifications (slack, mail, sentry or anything) when a job enters the dead queue.
An on_dead callback would do the job.
I could poll and check if there is dead jobs every x minutes but It's not ideal imo.

Do we have that? What would be the best way to achieve that?

Thanks!

Best approach would be to implement this:

Sidekiq.configure_server do |config|
  config.on(:dead) do |job_hash|
    # do something, e.g.
    # SlackNotifier.dead_job(job)
  end
end

That's what I'm looking for :)

Thank you!

Is this mentioned somewhere on the Wiki? Can't find it.

It's not implemented but would take about 10 lines of code. I look forward to your PR! :-)

Reading the code I found a similar feature available since 4.1.1 :

Sidekiq.configure_server do |config|
  config.default_retries_exhausted = -> (job, ex) do
    Sidekiq.logger.info "#{job['class']} job is now dead"
  end
end

If anyone got here late and nothing works, here is the right approach:

Sidekiq.configure_server do |config|
  config.death_handlers << ->(job, ex) do
    # do stuff
    # job keys: ["class", "args", "retry", "queue", "backtrace", "jid", "created_at", "enqueued_at", "error_message", "error_class", "failed_at", "retry_count", "error_backtrace"]
  end
end
