Metric Name Metric Type Description
ApplicationEventLogs WindowsEventLogEntry Tracks entries from the Windows Event Log (Application source)
AspNetApplicationRestarts WindowsPerformanceCounter Tracks the number of times that an application has been restarted during the Web server's lifetime. Application restarts are incremented each time an Application_OnEnd event is raised. An application restart can occur because of changes to the Web.config file, changes to assemblies stored in the application's Bin directory, or when an application must be recompiled due to numerous changes in ASP.NET Web pages. Unexpected increases in this counter can mean that problems are causing Web application to recycle.
AspNetErrors WindowsPerformanceCounter Tracks the average number of errors that occurred per second during the execution of HTTP requests. Includes any parser, compilation, or run-time errors.
AspNetRequests WindowsPerformanceCounter Tracks the number of requests executed per second. This represents the current throughput of the application. Under constant load, this number should remain within a certain range, barring other server work (such as garbage collection, cache cleanup thread, external server tools, and so on).
AspNetRequestsQueued WindowsPerformanceCounter Tracks the number of requests waiting for service from the queue. When this number starts to increment linearly with increased client load, the Web server computer has reached the limit of concurrent requests that it can process.
AspNetRequestsRejected WindowsPerformanceCounter Tracks the total number of requests not executed because of insufficient server resources to process them. This counter represents the number of requests that return a 503 HTTP status code, indicating that the server is too busy
AspNetRequestWaitTime WindowsPerformanceCounter Tracks the number of milliseconds that the most recent request waited in the queue for processing.
CpuTime WindowsPerformanceCounter Tracks overall CPU utilization on the monitored server
CurrentConnections WindowsPerformanceCounter Tracks the number of active connections with the Web Service. Like with the other web service counters, if the value of this counter is usually too big for the server (the actual number depends on the specific hardware and software installed), then load balancing solutions can be implemented.
DiskFreeSpace WindowsPerformanceCounterMultiInstance Tracks free space in Megabytes on each disk
DiskFreeSpaceTotal WindowsPerformanceCounter Tracks total amount of free space across all drives. Used in the Low Disk Space alert
DiskIdleTime WindowsPerformanceCounter Tracks the percentage of time when disk. Sustained numbers below 20% indicate an over-saturated disk.
DiskReadSpeed WindowsPerformanceCounter Tracks average time, in seconds, it takes to read data from the disk
DiskWriteSpeed WindowsPerformanceCounter Tracks average time, in seconds, it takes to write data to the disk
DynamicsNavActiveSession WindowsPerformanceCounter Tracks the number of active sessions on the Microsoft Dynamics NAV Server instance.

Under constant load, this number should remain within a certain range, barring other server work (such as garbage collection, cache cleanup thread, external server tools, and so on).
AspNetRequestsQueued WindowsPerformanceCounter Tracks the number of requests waiting for service from the queue. When this number starts to increment linearly with increased client load, the Web server computer has reached the limit of concurrent requests that it can process.
AspNetRequestsRejected WindowsPerformanceCounter Tracks the total number of requests not executed because of insufficient server resources to process them. This counter represents the number of requests that return a 503 HTTP status code, indicating that the server is too busy
AspNetRequestWaitTime WindowsPerformanceCounter Tracks the number of milliseconds that the most recent request waited in the queue for processing.
CpuTime WindowsPerformanceCounter Tracks overall CPU utilization on the monitored server
CurrentConnections WindowsPerformanceCounter Tracks the number of active connections with the Web Service. Like with the other web service counters, if the value of this counter is usually too big for the server (the actual number depends on the specific hardware and software installed), then load balancing solutions can be implemented.
DiskFreeSpace WindowsPerformanceCounterMultiInstance Tracks free space in Megabytes on each disk
DiskFreeSpaceTotal WindowsPerformanceCounter Tracks total amount of free space across all drives. Used in the Low Disk Space alert
DiskIdleTime WindowsPerformanceCounter Tracks the percentage of time when disk. Sustained numbers below 20% indicate an over-saturated disk.
DiskReadSpeed WindowsPerformanceCounter Tracks average time, in seconds, it takes to read data from the disk
DiskWriteSpeed WindowsPerformanceCounter Tracks average time, in seconds, it takes to write data to the disk

MemoryFree WindowsPerformanceCounter Tracks free memory (in MBs) on the monitored server
ProcessList WindowsProcessList Tracks list of Windows processes running on the virtual machine.
RecommendedActions AzureAdvisorRecommendationMetric Tracks recommended actions for specified resource.
SqlBatchRequests WindowsPerformanceCounter Measures the number of batches SQL Server is receiving per second. This counter is a good indicator of how much activity is being processed by your SQL Server box. The higher the number, the more queries are being executed on your box
SqlBlockedProcesses WindowsPerformanceCounter Tracks the number of blocked processes. When one process is blocking another process, the blocked process cannot move forward with its execution plan until the resource that is causing it to wait is freed up. Ideally there should not be any blocked processes
SqlBufferHitRatio WindowsPerformanceCounter The buffer cache hit ratio counter represents how often SQL Server is able to find data pages in its buffer cache when a query needs a data page. The higher this number the better, because it means SQL Server was able to get data for queries out of memory instead of reading from disk. You want this number to be as close to 100 as possible. Having this counter at 100 means that 100% of the time SQL Server has found the needed data pages in memory. A low buffer cache hit ratio could indicate a memory problem
SqlCompilations WindowsPerformanceCounter Measure the number of times SQL Server compiles an execution plan, per second. Compiling an execution plan is a resource-intensive operation. Compilations/Sec should be compared with the number of Batch Requests/Sec to get an indication of whether or not complications might be hurting performance. It is best when Compilations/sec are no more than 10% of overall Batch Requests/sec
SqlLockWaits WindowsPerformanceCounter Tracks the number of times per second that SQL Server is not able to retain a lock right away for a resource. Ideally requests should not be waiting a lock.
SqlPageLifeExpectancy WindowsPerformanceCounter The page life expectancy counter measures how long pages stay in the buffer cache in seconds. The longer a page stays in memory, the more likely SQL Server will not need to read from disk to resolve a query. Generally, times below 300 (or 5 minutes) might mean that additional memory is needed.
SqlPageSplits WindowsPerformanceCounter Tracks the number of times SQL Server had to split a page when updating or inserting data per second. Page splits are expensive, and cause table to perform more poorly due to fragmentation. The fewer page splits there are, the better system will perform. Ideally this counter should be less than 20% of the batch requests per second.
SqlRecompilations WindowsPerformanceCounter Measures the number of time a re-compile event was triggered per second. Re-compiles, like compiles, are expensive operations. Re-compiles happen when query's execution plan was invalidated due to some significant event,. It is optimal when re-compilations are no more than 10% of overall compilations/sec
SqlUserConnections WindowsPerformanceCounter Tracks the number of different users that are connected to SQL Server.
Status ResourceStatus Tracks the overall readiness status of the monitored resource. Possible values are: Ready, Down, Stopped and Unknown
SystemEventLogs WindowsEventLogEntry Tracks entries from the Windows Event Log (System source)
