File Activity
The File Activity panel displays the top five database files with the highest relative activity since the last refresh.
Lock Waits
The Lock Waits panel tracks the total number waits caused when a task is waiting to acquire a lock on your monitored SQL Server.
Disk SQL Server Physical I/O
The SQL Server Physical I/O chart breaks down the SQL Server throughput into its key component pieces, giving you a detailed view of how well the SQL Server is processing your data requests and updates.
Disk Throughput
The Disk Throughput chart plots the number of disk reads and writes over time.
Memory SQL Server Usage
The SQL Server Usage chart compares the amount of memory allocated and used by SQL Server to the total memory consumed by a computer.
Memory Paging
The SQL Server Paging chart plots the number of swapped pages per second, over time, as calculated by the memory paging metric.
Memory Usage
The Memory Usage chart compares the amount of memory allocated and used by SQL Server to the total memory consumed by this virtual machine.
Network Response Time
The Response Time gauge displays the time (in milliseconds) SQL diagnostic manager currently needs to send a simple SQL command to the SQL Server instance, have it processed, and receive the returned result set.
Network Throughput
The Throughput chart plots how many packets this SQL Server sends and receives over time.
Server Waits
The Server Waits panel tracks the total number and time spent on waits affecting your monitored SQL Server.
Session Activity and Blocking
The Activity and Blocking chart displays the total number of active sessions on your monitored SQL Server instance and any blocking or deadlocks that may occur between sessions.
