      "base_url": "https://sqs.<REGION>.amazonaws.com/<YOUR_AWS_ACCOUNT_NUMBER>/<QUEUE_NAME>"
    }
  }
}

Secure It

Monitor It

Create an inactivity alert to detect interruptions of transfer of data from the source to the SQS queue using the query

from TABLE 
where toktains(hostchain,"collector-") 
select split(hostchain,"-",1) as collector_id

Set the inactivity alert to keep track of the collector_id.
