Monitoring SMS
Monitoring SMS Activity
You can use Performance Monitor utility to track various processes on a Windows system in real time. The utility uses a graphical display that you can use to view current data, or log data. You can specify specific elements or components that should be tracked. You can determine resource usage by monitoring trends.
With Performance Monitor, objects, counters and instances are used to monitor the system. An object is a collection of counters which are associated with a system resource or service. As the object executes a function, its associated counters are updated. A counter represents data for a particular component of the system or service. Each object has a set of counters. An instance refers to the incident of multiple performance objects of the identical type on a computer. An object can have one or multiple instances.
The objects most commonly used to monitor network activity are listed below:
- Browser object, monitors the Browser service for the domain or the workgroup
- Cache object, monitors disk cache usage
- Memory object, monitors physical and virtual memory performance
- Objectsobject, monitors the events, processes and threads on the computer as data is collected.
- Paging File object, monitors page file usage
- Physical Disk object, monitors the hard disks
- Process object, monitors the processes running on the computer
- Processorobject, monitors the processors on the system.
- Server object, monitors items such as bytes, sessions, pool paged usage, and pool non-paged usage.
- System object, monitors counters associated with system hardware and software
- Thread object, monitors threads running in the system
When you install SMS 2.0, a number of SMS specific counters are added in Performance Monitor, and are displayed when the SMS site server is started. In addition to using SMS specific performance counters, there are a number of other objects and counters that should be used to monitor system performance, and identify resource and processing bottlenecks.
The subsystems which should be monitored when monitoring system performance are listed below:
- Memory subsystem
- Network subsystem
- Processor subsystem
- Processes subsystem
- Disk subsystem
It is recommended that you use the following Performance Monitor objects and counters to monitor overall SMS system performance, detect disk usage issues, and identify resource and processing bottlenecks:
- Memory\Committed Bytes:This counter indicates the number of committed bytes of virtual memory on the system, and should be monitored together with the Memory\Available Bytes counter if you suspect that a memory leak exists.
- Memory\Available Bytes: The counter indicates what your available memory capacity is. To efficiently run a server, you need to have at least 4MB of memory available. When the memory drops below 4MB, you might need to immediately add more memory.
- Memory\Pages/Sec: With a recommended counter threshold of 20, this counter indicates the rate at which pages are written to disk or read from disk. The counter should generally be beneath 20.
- Network Interface\Bytes Total/sec; Bytes Sent/sec; Bytes Received/sec: These counters indicate the manner in which your network adapters are performing in relation to network traffic.
- Physical Disk\% Disk Time; Physical Disk\ Avg. Disk Queue Length: A memory shortage would exist if an increase in queue length is not followed by a decrease in the Memory\ Page Read/Sec counter value. System performance is typically satisfactory if the Physical Disk\% is equal to, or lower than 80 percent.
- Physical Disk\ Current Disk Queue Length: The counter indicates the number of requests which are in queue for disk access. The counters should be consistently at 1.5 to 2 times the number of spindles which comprise of the physical disk.
- Physical Disk\ Disk Reads/Sec and Disk Writes/Sec: These counters show the speed at which data is written to disk and read from disk. The information of these counters could assist you in more efficiently balancing the load of your servers. A lengthy delay could be indicative of a hard disk issue. When usage is close to the defined transfer rate of the physical disk, you might need to consider decreasing the load of the server. You could also upgrade to RAID.
- Processor\% Processor Time: This counter should be tracked if you want to detect a process which is utilizing over 85 percent of the processor time. In this case, you might have to consider either upgrading the processor, or installing an additional processor.
- Processor\% User Time: This counter indicates the non-idle processor time percentage which takes place in user mode. If the value of the counter is constantly high, consider upgrading the processor, or installing an additional processor.
- Processor\ Interrupts/Sec: This counter shows the number of interrupts which are being received from devices. An increase in the counter’s value should be accompanied by an increase in system activity. If not, you could have an existing hardware issue that needs to be resolved.
- SQL Server\ ache Hit Ratio: Shows the number of times that SQL Server requests were resolved using the SQL Server cache instead of querying the SQL databases.
- Server\Bytes Total/Sec: This counter indicates how busy the server is, and displays the number of bytes which the server has sent to and received from the network. A drastic increase in this counter value could indicate that you need to add more memory.
- Server Work Queues\Queue Length: The counter shows what the queue length of the Server Work queue is. An acceptable value for this counter is four. If there are constantly over four items in the queue, it could be indicative of processor congestion.
- System\ Processor Queue Length: This counter shows the number of requests waiting in queue to be processed. If you constantly have a queue length of over 10 for a processor, you may have an existing bottleneck.

The SMS Trace utility can be used to display and view SMS log file content. With the SMS Trace utility, you can open and view multiple log files at the same time. You can also search and select text. The log file view displayed in the SMS Trace utility is also dynamically updated as the log file changes. This means that all new log file entries are displayed without you having to reopen the file. The SMS Trace utility is not automatically installed when you install the SMS site server. You have to manually install the utility.
The SMS 2.0 installation CD-ROM contains a number of troubleshooting tools located beneath the \SUPPORT\RESKIT directory which you can utilize for the following tasks:
- Manage the site hierarchy and the site database.
- Manage and examine inventory and software distribution
- Examine client computer discovery data
- Manage and remove client components
- Configure the Remote Tools Client Agent
- Examine the log files and to schedule files
