How to find when a specific task/inventory has run

Hi Guys,

I have a query.

We have multiple tasks and jobs that run on our client PC's including 2 levels of inventory.

Does anyone know where to find where we can see the time a specific inventory ran on a specific client PC.

I have found the Inv_Inventory_results table which gives me the client guid, the agent type, version, collection time and class count.

This gives me the client PC and that the inventory agent ran, but not which inventory ran.

Also I do not understand the class count, can anyone clarify this item.

Thanks in advance
