Performance Monitoring

Template: 1 2

The Windows NT Server Manager performs basic analysis of a running server. Statistics such as the number of current user connections, idle time on a connection, and share names in use can be viewed with this tool. These statistics can be collected for multiple servers in the network enabling centralized planning.

The Windows NT Performance Monitor can simultaneously monitor objects and counters for one or more computers in a network. Real-time analysis of data is possible as well as logging of data for later viewing. The performance monitor is the primary data gathering tool for capacity planning.

The Windows NT Diagnostic tool displays the current system configuration including processor, memory, disk and network information.

Server Configuration Options.

Option	Description
Minimize Memory Used	For use with up to ten simultaneous connections from client computers. This would be useful for a server that has a user running desktop applications locally.
Balance	For use with up to 64 simultaneous connections.
Maximize Throughput for File Sharing	For use with large number of clients in a file and print server environment.
Maximize Throughput for Network Applications	For use in an applications server environment.

Performance Monitor Counters Application Server Workload Units

Workload Unit	Performance Monitor Counter
Concurrent user sessions	Server: Server Sessions
Processor utilization	Processor: % Processor Time
Average disk transaction size	Physical Disk: Avg. Disk Bytes/Transfer
Amount of disk activity	Physical Disk: % Disk Time
Network use	Network Segment: % Network Utilization
Average network transaction size	Will vary for protocol, such as NetBEUI: Frame Bytes/sec
Available memory	Memory: Available Bytes
Amount of paging	Memory: Pages/sec
Usage of cache	Cache: Data Map Hits %

Logon Server Workload Units

Workload Unit	Performance Monitor Counter
Concurrent logons	Server: Logon/sec
Total logons since system startup	Server: Logon Total
Memory use	Memory: Available Bytes Memory: Committed Bytes
Network use	Network Segment: % Network Utilization
NetBIOS name service registrations	WINS Server: Total Number of Registrations/sec
NetBIOS name queries	WINS Server: Queries/sec

The following table lists Performance Monitor counters of interest along with target ranges and suggested actions to achieve the desired results. These numbers should be treated as guidelines only.

Performance Monitor Objects

Counter	Description	Acceptable Average Range	High or low desired value?	Action
Pages/sec	This is the number of requested pages that were not immediately available in RAM, and thus, had to be accessed from the disk.	0 to 20	lower	Find process causing paging or add RAM.
Available Bytes	This indicates the amount of available physical memory. It will normally be low, as the Windows NT Disk Cache Manager will consume extra memory for caching, returning it when requests for memory occur.	4 MB or greater	higher	Find process(es) using RAM or add RAM.
Committed Bytes	Indicates the amount of virtual memory that has been committed to either physical RAM for storage or page file space.	< total physical memory	lower	Find process(es) using RAM or add RAM.
Pool Paged Bytes	Indicates the amount of RAM in the Paged Pool that can be paged out when not accessed by the system.	Should remain steady		Check for memory leak in application
Pool Non-paged Bytes	The amount of RAM in the Non-paged pool that cannot be paged out even when not being accessed.	Should remain steady		Check for memory leak in application
% Processor Time	Measures the amount of time the processor is busy executing non-idle threads (performing some work).	< 75%	lower	Find busy process(es). Upgrade processor.
Interrupts /sec	the number of device interrupts the processor is servicing from applications or hardware devices. On a x86 system, 100 interrupts per second are a minimum, as the processor clock generates 100 interrupts per second.	100 to 2000	lower	Find controller generating interrupts
System: Processor Queue Length	The number of requests the processor has in its queue. It indicates the number of threads that are ready to be executed, and are waiting for processor time	0 to 2	lower	Upgrade or add processor
% Disk Time	Indicates the amount of time the disk drive is busy servicing read and write requests.	< 50%	lower	Check for paging. Upgrade disk subsystem.
Disk Queue Length	Indicates the number of pending disk I/O requests for the disk drive. If this value is consistently over two, it indicates congestion.	0 to 2	lower	Upgrade disk subsystem.
Server: Bytes Total/sec	The number of bytes the server has sent and received over the network. It indicates how busy the server is for transmission and reception of data.	Function of # of NICs and protocol used.	Higher	Analyze further or add a NIC.
Network Segment: % Network utilization	The percentage of the network bandwidth in use for the local network segment. This can be used to monitor the affect different network operations have on the network.	< 30% for non-switched networks	Lower	Segment the network or limit protocols used.
Network Interface: Bytes Sent/sec	Is the number of bytes sent using this network adapter.	Function of NIC and protocol	Higher	Upgrade NIC or physical net.
Network Interface: Bytes Total/sec	Is the number of bytes sent and received using this network adapter.	Function of NIC and protocol	Higher	Upgrade NIC or physical net.
TCP Segments /sec	The number of TCP segments (frames) that are sent and received over the network.	Function of activity	Higher	Reduce broadcasts. Segment network.
TCP Segments Re-transmitted/sec	The number of frames (segments) that are re-transmitted on the network.		Lower	Upgrade network hardware. Segment network.
UDP Datagrams/sec	The number of UDP datagrams (for example broadcasts) that are sent and received.	Function of activity	Higher	Reduce broadcasts.
