Many CSP partners offer this as a service (sometimes called managed services or proactive monitoring), using tools like Azure Monitor and Azure Advisor to watch for performance issues, security risks, or cost anomalies before they become bigger problems — but this isn't automatically included with every CSP relationship by default.
If proactive monitoring is something you want, it's worth asking specifically whether it's included or available as an add-on with a given partner.
If you'd like proactive monitoring of your Azure environment rather than only reacting when something breaks, that's a service we offer.
