Application Pool monitoring in Log Analytics

CliveWatson 

IS the anyway to query IIS Logs and currently what I observe is we are fetching data based on the EventLog and querying System Logs , but here we are only able to fetch the status Shutdown and not all status of App Pool , since if at all we need identify the health or status of the AppPool before shutdown it can only be useful and based on that we can generate the alert and take the corrective action.

Also I was wondering if we make use of Application Insights to achieve this and how does the Azure Log Analytics is different from these .

Please let me know your thoughts in regards to the same and is there any ways to query the IIS logs.
