Developers can create custom views and set up Slack alerts to monitor resource costs and usage, without spending all day monitoring the views. However, Slack may not always be the primary collaboration tool for developers. Additionally, receiving an alert is not the end goal, as certain actions are triggered when specific alerts are received, such as creating a ticket on Jira/Linear to be tackled by the infrastructure team, triggering an alert on an incident & response platform like PagerDuty, or even running a custom script to resize the infrastructure.
