Queue depth on order-processing jumped from a ~700 message baseline to 8,400 over the last 90 minutes. Consumer throughput dropped 74% at 14:22 UTC, correlating with the deploy to order-service v2.11.3. Oldest message age is now 47 minutes and climbing.
An agent watches one thing and acts on it. Not a workflow, just a standing watch that usually does nothing and acts the moment it should.
An agent does what you'd do, and only what you've authorized.
It acts on the same governed metrics as your dashboards, and every action is logged and traceable.
It alerts and recommends on its own; anything that changes data is yours to approve.
Point a new agent at a throwaway channel and watch its judgment before it touches anything real.
It remembers what it already flagged and waits before acting again, so it won't alert you about the same thing twice.
It joins your SQS message data to your deploy log and service health metrics, so a queue backing up isn't just a depth number; it's a release, a consumer, and a blast radius you can see. You find out which change broke throughput before you are the one manually checking CloudWatch and cross-referencing deploys.
When message volume or processing rate breaks its trend, it tells you which queue, when the shift started, and whether consumer lag is growing. You spot a producer spike or a consumer stall the day it begins, not when a downstream job times out and someone pings you.
It watches message attributes and payload patterns over time. When a new attribute appears, a required field goes missing, or message bodies start carrying unexpected structures, it surfaces the change so you catch the schema drift before it causes silent failures downstream.
Beyond alerts and write-backs, an agent can run arbitrary Python, so it can do whatever the task actually requires: call an API, kick off a job, reshape the data, or wire into your own tooling. The action space is yours to define.
You could rig one of these with a cron job and a Slack webhook in an afternoon. The watching is the easy part. Here's what you'd own forever, and don't, here:
Every Amazon SQS object, modeled and query-ready the moment you connect.
It runs on your real SQS queues (retry storms, poison pills, dead-letter overflow and all), not a tidy demo.
A message in the channel you choose, with the context and a button to act on it.
A summary in the inbox of the people who need to see it.
A payload to your own systems, to wire the agent into whatever you already run.
A flag written back to your warehouse for everything downstream to pick up.
