Try this as a query against the Log Analytics Resource.
Reference: https://learn.microsoft.com/en-us/rest/api/loganalytics/dataaccess/query/get
let usedMemory = Perf | where (ObjectName == 'Memory' and CounterName contains 'Committed Bytes') | summarize UsedMemory = (avg(CounterValue)) by Computer; let AvailMemory = InsightsMetrics | extend localTimestamp = TimeGenerated - 7h | where TimeGenerated > ago(1d) | where Namespace == 'Memory' and Name == 'AvailableMB' | extend AvailableMem = Val | summarize arg_max(TimeGenerated, *) by Computer; AvailMemory | join kind=leftouter usedMemory on Computer | extend FreeMemoryGB = round(AvailableMem/1024) | parse Tags with * ':' TotalMemoryMB '}' Err | project Computer, FreeMemoryGB, UsedMemory, TotalMemoryMB, localTimestamp, Namespace, Tags, AgentId, _ResourceId
