+## Job Monitoring
+
+Standard job frameworks such as `ActiveJob` and `Sidekiq` with a `perform` method can use the `Sentry::Cron::MonitorCheckIns` mixin module to automatically capture check-ins.
+
+```rb {tabTitle: ActiveJob}
+class ExampleJob < ApplicationJob
+  include Sentry::Cron::MonitorCheckIns
+
+  sentry_monitor_check_ins
+
+  def perform(*args)
+    # do stuff
+  end
+end
+```
+
+```rb {tabTitle: Sidekiq}
+class SidekiqJob
+  include Sidekiq::Job
+  include Sentry::Cron::MonitorCheckIns
+
+  sentry_monitor_check_ins
+
+  def perform(*args)
+    # do stuff
+  end
+end
+```
+
+You can pass in optional attributes to `sentry_monitor_check_ins` as follows.
+
+```rb
+# slug defaults to the job class name
+sentry_monitor_check_ins slug: 'custom_slug'
+
+# define the monitor config with an interval
+sentry_monitor_check_ins monitor_config: Sentry::Cron::MonitorConfig.from_interval(1, :minute)
+
+# define the monitor config with a crontab
+sentry_monitor_check_ins monitor_config: Sentry::Cron::MonitorConfig.from_crontab('5 * * * *')
+```
+
+## Manual Setup
+
+### Check-Ins (Recommended)
+
+Check-in monitoring allows you to track a job's progress by completing two check-ins: one at the start of your job and another at the end of your job. This two-step process allows Sentry to notify you if your job didn't start when expected (missed) or if it exceeded its maximum runtime (failed).
+
+```ruby
+check_in_id = Sentry.capture_check_in('<monitor-slug>', :in_progress)
+# Execute your scheduled task here...
+Sentry.capture_check_in('<monitor-slug>', :ok, check_in_id: check_in_id)
+```
+
+If your job execution fails, you can notify Sentry about the failure:
+
+```ruby
+Sentry.capture_check_in('<monitor-slug>', :error, check_in_id: check_in_id)
+```
+
+### Heartbeat
+
+Heartbeat monitoring notifies Sentry of a job's status through one check-in. This setup will only notify you if your job didn't start when expected (missed). If you need to track a job to see if it exceeded its maximum runtime (failed), use check-ins instead.
+
+```ruby
+Sentry.capture_check_in('<monitor-slug>', :ok)
+```
+
+If your job execution fails, you can notify Sentry about the failure:
+
+```ruby
+Sentry.capture_check_in('<monitor-slug>', :error)
+```

+### How Do I Send an Attachment With a Check-in (Such as a Log Output)?
+
+Attachments aren't supported by our Ruby SDK yet. For now, you can use the [check-in attachments API](/product/crons/getting-started/http/#check-in-attachment-optional).

 Sentry Crons allows you to monitor the uptime and performance of any scheduled, recurring job. Once implemented, it'll allow you to get alerts and metrics to help you solve errors, detect timeouts, and prevent disruptions to your service.
