# See What Happened

Blossom records every deploy, and everything your App prints, so you always
know what happened. Ask your agent:

> What happened in my last deploy?

Here's where it looks.

## Every Deploy

Each deploy's Activity has its build and release log, start to finish:

    blossom activity:list
    blossom activity:logs --id activity-100

Releases list what's running now and what ran before:

    blossom release:list --environment environment-100

## Your App

For what your App itself printed:

    blossom logs --environment environment-100

When something needs your attention, such as a Service that won't start or a
health check that keeps failing, Blossom records it with the reason:

    blossom runtime_issue:list --environment environment-100

## What You Get

- A full record of every deploy, its build and its release
- Your App serving the last good version if a new one doesn't come up, with
  the reason why
- `release:rollback` to go back to any earlier Release in one step
