Send to Sentinel logs from many Log Analytics

Artem_Rozhko An Azure Sentinel instance can only work against 1 Log Analytics workspace. You have a few options here. 1) Have all the resources send their logs to a single Log Analytics workspace and have Azure Sentinel use that. (probably the best solution if feasible) 2) Use something like an Event Hub and have the other 12 workspaces send their data into the 1 that Azure Sentinel uses (not recommended) 3) Create an Azure Sentinel instance for each Log Analytic workspace and then use Azure Lighthouse to provide an overall picture of all the incidents that occur. Basically treating your environment like a MSSP (2nd best option but easiest to implement). Just remember that if you do associate a Log Analytics workspace with Azure Sentinel there is an additional ingestion cost added.

Wow, thanks Gary for this ultimate answer! I suppose we will use first one option.
