Dendrite — Background Jobs Built for AI

Why is the email queue backed up? Users are complaining about delayed notifications.

I'd like to help, but I can't see your job queues.

I don't have access to Sidekiq, queue depths, or job failures.

Could you check the Sidekiq dashboard and share what you see?

Let me check the queues...

Using dendrite.get_queue_stats

dendrite.get_queue_stats(queue: "mailers")

Response

mailers queue — CRITICAL

Pending: 47,832 jobs

Failed: 2,341 jobs (same error)

Throughput: 0 jobs/min (stuck)

The mailer queue is completely stuck. Let me check the failures...

Using dendrite.get_failed_jobs

dendrite.get_failed_jobs(queue: "mailers", limit: 1)

Error

Net::SMTPAuthenticationError

535 Authentication failed: API key expired

Found it. The SendGrid API key expired. Let me check Vault for a new key...

Root cause: SendGrid API key expired 2 hours ago.

I've rotated the key via Vault and restarted workers. Queue is draining now.

Queue cleared: 12 minutes

The Difference

Without Dendrite

— Claude can't see job queues
— You discover issues from users
— Manual Sidekiq investigation
— No automatic recovery

With Dendrite

+ Claude sees every queue, every job
+ AI detects backlogs before users
+ Automatic root cause analysis
+ AI fixes what it can

How It Works

1

Works with your existing setup

Sidekiq, Solid Queue, Good Job—we integrate with them all.

# No changes to your jobs

class WelcomeEmailJob < ApplicationJob

queue_as :mailers

end

2

Monitor everything

Queue depths, throughput, failures, latency—all visible to AI.

mailers 234 pending

3

AI manages automatically

Retry failed jobs, scale workers, adjust priorities.

dendrite.retry_failed("mailers")

dendrite.scale_workers("critical", count: 5)

4

Correlate with errors

Job failures connect to Reflex errors and Vault secrets.

Job failure linked to expired API key in Vault

The Tools AI Uses

Available via MCP (Model Context Protocol)

dendrite.get_queue_stats()

"How are the queues?"

dendrite.get_failed_jobs()

"What jobs are failing?"

dendrite.retry_job(id)

"Try this one again"

dendrite.pause_queue(name)

"Stop processing mailers"

Get Started

One gem. Zero config. Works in 30 seconds.

# Add to your Gemfile

gem 'brainzlab'

# Run bundle

$ bundle install

# That's it. Job monitoring is active.
