\Memory\Available Mbytes

Available MBytes is the amount of physical memory, in Megabytes, immediately available for allocation to a process or for system use. It is equal to the sum of memory assigned to the standby (cached), free and zero page lists.

N/A

\Memory\Pages/sec

Pages/sec is the rate at which pages are read from or written to disk to resolve hard page faults. This counter is a primary indicator of the kinds of faults that cause system-wide delays.  It is the sum of Memory\\Pages Input/sec and Memory\\Pages Output/sec.  It is counted in numbers of pages, so it can be compared to other counts of pages, such as Memory\\Page Faults/sec, without conversion. It includes pages retrieved to satisfy faults in the file system cache (usually requested by applications) non-cached mapped memory files.

Near 0.

This is an indicator of how often page files are written or read from disk. High values indicate low memory management.

\Memory\Pages Input/sec

Pages Input/sec is the rate at which pages are read from disk to resolve hard page faults. Hard page faults occur when a process refers to a page in virtual memory that is not in its working set or elsewhere in physical memory, and must be retrieved from disk. When a page is faulted, the system tries to read multiple contiguous pages into memory to maximize the benefit of the read operation. Compare the value of Memory\\Pages Input/sec to the value of  Memory\\Page Reads/sec to determine the average number of pages read into memory during each read operation.

Near 0.

Occasional spikes are expected.

\Memory\Pool Nonpaged Bytes

Pool Nonpaged Bytes is the size, in bytes, of the nonpaged pool, an area of the system virtual memory that is used for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated.  Memory\\Pool Nonpaged Bytes is calculated differently than Process\\Pool Nonpaged Bytes, so it might not equal Process(_Total)\\Pool Nonpaged Bytes.  This counter displays the last observed value only; it is not an average.

N/A

\Memory\Pool Paged Bytes

Pool Paged Bytes is the size, in bytes, of the paged pool, an area of the system virtual memory that is used for objects that can be written to disk when they are not being used.  Memory\\Pool Paged Bytes is calculated differently than Process\\Pool Paged Bytes, so it might not equal Process(_Total)\\Pool Paged Bytes. This counter displays the last observed value only; it is not an average.

N/A

\Memory\% Committed Bytes in Use

% Committed Bytes In Use is the ratio of Memory\\Committed Bytes to the Memory\\Commit Limit. Committed memory is the physical memory in use for which space has been reserved in the paging file should it need to be written to disk. The commit limit is determined by the size of the paging file.  If the paging file is enlarged, the commit limit increases, and the ratio is reduced). This counter displays the current percentage value only; it is not an average.

Less than 50%.

\Network Interface(*)\Packets Received Errors

Packets Received Errors is the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Near 0.

\Network Interface(*)\Output Queue Length

Output Queue Length is the length of the output packet queue (in packets). If this is longer than two, there are delays and the bottleneck should be found and eliminated, if possible. Since the requests are queued by the Network Driver Interface Specification (NDIS) in this implementation, this will always be 0.

Less than 2.

Higher than an average of 2 indicates a network bottleneck.

\Network Interface(*)\Bytes Total/sec

Bytes Total/sec is the rate at which bytes are sent and received over each network adapter, including framing characters. Network Interface\Bytes Total/sec is a sum of Network Interface\Bytes Received/sec and Network Interface\Bytes Sent/sec.

N/A

\PhysicalDisk(_Total)\Avg. Disk sec/Read

Avg. Disk sec/Read is the average time, in seconds, of a read of data from the disk.

Near 0.

Useful metric for determining disk latency. Higher values are bad.

\PhysicalDisk(_Total)\Avg. Disc sec/Transfer

Avg. Disk sec/Transfer is the time, in seconds, of the average disk transfer.

Near 0.

Useful metric for determining disk latency. Higher values are bad.

\PhysicalDisk(_Total)\Avg. Disk sec/Write

Avg. Disk sec/Write is the average time, in seconds, of a write of data to the disk.

Near 0.

Useful metric for determining disk latency. Higher values are bad.

\PhysicalDisk(*)\Current Disk Queue Length

Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It also includes requests in service at the time of the collection. This is a instantaneous snapshot, not an average over the time interval. Multi-spindle disk devices can have multiple requests that are active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests experience delays proportional to the length of this queue minus the number of spindles on the disks. For good performance, this difference should average less than two.

2-3 per spindle during idle.

During spikes, check correlation to \Memory\Pages Input/sec

\PhysicalDisk(_Total)\Disk Bytes/sec

Disk Bytes/sec is the rate bytes are transferred to or from the disk during write or read operations.

N/A

Check Correlation between this and \PhysicalDisk\Current Disk Queue Length and \Memory\Pages Input/sec.

\PhysicalDisk(_Total)\% Idle Time

% Idle Time reports the percentage of time during the sample interval that the disk was idle.

Very low idle time indicates either the system is being overutilized or the disk isn't responsive enough. Compare to physical disk metrics. A very high idle time indicates the server is being underutilized.

\Process(_Total)\Working Set

Working Set is the current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use.  When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before leaving main memory.

N/A

Useful for comparison to the \Memory metrics.

\Processor(_Total)\%Processor Time

% Processor Time is the percentage of elapsed time that the processor spends to execute a non-Idle thread. It is calculated by measuring the percentage of time that the processor spends executing the idle thread and then subtracting that value from 100%. (Each processor has an idle thread that consumes cycles when no other threads are ready to run). This counter is the primary indicator of processor activity, and displays the average percentage of busy time observed during the sample interval. It should be noted that the accounting calculation of whether the processor is idle is performed at an internal sampling interval of the system clock (10ms). On todays fast processors, % Processor Time can therefore underestimate the processor utilization as the processor may be spending a lot of time servicing threads between the system clock sampling interval. Workload based timer applications are one example  of applications  which are more likely to be measured inaccurately as timers are signaled just after the sample is taken.

Less than 50%

With high values, compare to processor queue length to determine total load on the system.

\Processor(_Total)\% Idle Time

% Idle Time is the percentage of time the processor is idle during the sample interval

50% or more.

This, with \Processor(_Total)\% Processor Time, helps us understand how much time is spent context switching.

\System\Processor Queue Length

Processor Queue Length is the number of threads in the processor queue.  Unlike the disk counters, this counter counters, this counter shows ready threads only, not threads that are running.  There is a single queue for processor time even on computers with multiple processors. Therefore, if a computer has multiple processors, you need to divide this value by the number of processors servicing the workload. A sustained processor queue of less than 10 threads per processor is normally acceptable, dependent of the workload.

Less than 10 per processor.

\TCPv4\Connection Failures

Connection Failures is the number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.

N/A

This is an aggregator since the last system restart. Examine the delta between samples. A high change could be an indicator of network issues.

\TCPv4\Connections Established

Connections Established is the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.

This tells us how many active connections are present.

\TCPv4\Connections Reset

Connections Reset is the number of times TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state.

N/A

This is an aggregator since the last system restart. Examine the delta between samples. A high change could be an indicator of network issues.

Process Object : % Processor Time : sqlservr

CPU Time consumed by the SQLSERVR process (Microsoft SQL Server service process).

SQL Server Access Methods Object : Full Scans / Sec

Full Scan Access Method is bypassing all indexes and may indicate sub-optimal performance. Certain amount of full-scan accesses cannot be prevented, but extensive usage of Full Scan accesses should trigger analysis and optimization.

SQL server Databases : Active transactions : All instances

Number of cuncurrently running transaction. Should not exceed long-term observed threshold. While this number is closely related to user activity happening in the system, having this metric grow continuously over a long periods of time may indicate problems.

SQL server Databases : Transactions/sec : All instances

Performance oriented metric indicating database engine throughput.

SQL server: Transactions: Longest Transaction Running time

Transactions represent database operations, which are all time bound. Some transactions are long running, but no transactions should run indefinitely.

SQL Server Buffer Manager Object : Cache Hit Ratio (Buffer Cache hit ratio)

Performance oriented metrics. If the cache hit ratio is steadily low, analysis of the performance profile should be triggered to optimize cache utilization.

SQL Server General Statistics Object : User Connections

Number of concurrent user connections. While there can be up to hundreds of concurrent connections, this number should not exceed certain threshold. Please refer to SafeQ configuration to determine such threshold.

• Example: if the connection pool size in SafeQ is configured to 100 concurrent connections, this number should generally stay below this number. If it does not, that indicates connection pool exhaustion which should trigger an alert.

SQL Server Locks Object : Average Wait Time : All instances

Average wait time on SQL Server locks - for mutual exclusions on shared resources. Wait time should stay below or around certain observed threshold. If this number is steadily growing, that may indicate a problem.

SQL Server Locks Object : Number of deadlocks /sec: All instances

Deadlocks indicate deadlocked transactions.
