This graph shows how TempDB has been used over time. This graph is useful for understanding how TempDB is being used over time.
This graph is also useful for understanding incidents caused by TempDB space issues. A relatively common cause of transaction failures is space exhaustion in TempDB. The occurrence of this may cause the related transaction to fail however while space is exhausted may also cause other transactions to fail.
The graph shows the allocation size of the TempDB (grey) and the space consumed at the time during the specified period (yellow). To investigate detail of the space usage, it is suggested that you drill into TempDB query details.
