The CPU Usage chart displays the percentage of the processing power on the computer that hosts the SQL Server instance over a period of time.
CPU Processor Queue Lenght
The The CPU Processor Queue Length graph displays the current value of the processor queue length metric. Use this metric to determine how much work is waiting on this server.
CPU Call Rates
The The CPU Call Rates chart displays a details breaks down the processor workload into the number of batches, compilations, and transactions completed each second. Through this chart, you can get a detailed view of the resource-intensive activities.
Cache Areas
The The Cache Usage chart displays the usage in megabytes of each type of cache in use on your instance.
Cache Hit Ratio
The The Cache Hit Ratios gauge displays the hit rates of the Buffer and Procedure cache in the monitored SQL Server instance. Configure the Procedure Cache Hit Ratio (Percent) alert to warn you about any issue related.
Custom Counters
The The Custom Counters panel displays the statistics of a selected custom counter on a monitored SQL Server instance.

SQL Server instance.
Databases
The Databases panel tracks the performance of the databases on your monitored SQL Server.
Disk Latency
The The Disk Latency chart plots the average time (in milliseconds) required to complete disk reads and writes, tracking the disk IO speed over time.
Cache Page Life Expectancy
The The Page Life Expectancy chart provides the time in seconds that a page remains in the cache or buffer pool. The longer your page stays in the cache, the more likely the chance that SQL Server finds that data quickly without a read of physical media and minimizes processing resource use. Use the Page Life Expectancy alert to warn you of issues.
File Activity
The The File Activity panel displays the top five database files with the highest relative activity since the last refresh.
Lock Waits
The 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 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 The Disk Throughput chart plots the number of disk reads and writes over time.
Memory SQL Server Usage
The 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 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 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 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 The Throughput chart plots how many packets this SQL Server sends and receives over time.
Server Waits
The The Server Waits panel tracks the total number and time spent on waits affecting your monitored SQL Server.
Session Activity and Blocking
The 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.
Session Client Computers
The The Client Computers graph displays the total number of unique client computers connected to the SQL Server instance.
