Monitoring FOR PROCESSOR BOTTLENECKS
MAJOR PROCESSOR RELATED COUNTERS TO WATCH:
Processor: % Processor Time & # 8211 ; How busy the microprocessor is. Processor is a constriction if sustained & gt ; 80 %
Processor: Interrupts/sec & # 8211 ; Rate of service petitions from peripheral devices. If you have a high rate of interrupts/sec with no matching hardware maps so you may hold a bad piece of hardware. Should be between 100 and 1000. Spikes to 2000 are all right.
System: Processor queue length & # 8211 ; Number of togss waiting to be serviced. & gt ; 2 so processor is a constriction. Queue length will ever be zero unless you are besides supervising a yarn specific counter ( Context switches/sec is figure of togss switched/sec by the processor and is good to utilize ) .
Monitoring THE DISK FOR BOTTLENECKS
IF THE DISK LIGHT IS ON ALL THE TIME, YOU NEED MORE RAM
More Ram will increase the size of the disc cache and lessening page trading to disc and will increase the evident velocity of the disc.
Logical disc V. Physical disc
Two different objects in Performance proctor.
Logical disc steps public presentation of stripe sets, volume sets and mapped web thrusts.
Physical disc steps existent transportations to and from existent difficult disc or RAID set. Used to compare discs and to supply specific information about a disc.
Major DISK RELATED COUNTERS TO WATCH:
Memory: Pages/sec shows the figure of memory pages swapped out to harrow per second. Useful with % disc clip: modify the size of the page file and watch the consequence of these two disc counters.
% Disk clip does non straight mensurate the disc. It shows how much clip the processor is passing serving Dis
K petitions. Use with Processor: % Processor Time to find if the disc is eating up the processor.
Disk bytes per second shows how fast your disc is. Copy a large file and see if your disc is manner fast or a piece of debris.
Average disc bytes per transportation shows how large the mean transportation is. Larger transportations are more efficient.
Current Disk waiting line length shows how much information is waiting to be transferred to harrow. A long waiting line means you need a faster disc.
Note: You must enable disc counters, they are disabled by default and will do a debasement of approximately 2 % in public presentation due to processor burden of the counter.
To enable disk public presentation counters: type diskperf -y at the bid prompt to enable car counter startup at boot. Reboot.
To disable disc public presentation counters: type diskperf -n at the bid prompt to disable car counter startup at boot. Reboot.
NETWORK MONITOR
Is a cut down version of what ships with SMS.
Is installed by adding Network proctor tools and agent through the services check of the web icon in control panel.
Can supply existent clip and cumulative saved informations.
FOUR MAIN SECTIONS
Bar graph in existent clip.
Session statistics shows cumulative informations about conversations taking topographic point on the web in existent clip.
Station statistics shows information on each conversation. You must stipulate the machine ( station ) you want to supervise and is cumulative for the monitoring period.
Drumhead statistics are cumulative and show web, captured, per second, NIC ( MAC ) , and NIC mistake statistics.
Datas can be filtered by protocol, computing machine reference, or protocol belongingss. Filter by computing machine reference to place a NIC sending informations frames when non in usage ( bad NIC ) .
Netmon can be double watchword protected and will allow you place other cases of Netmon running on the web. This is to forestall unauthorised users from capturing informations to which they do non hold permission to entree.
? ? ? Conflict? ? ?
Sybex Network Press: MCSE NT Server 4 Study Guide says, ? The limited version of web proctor that ships with Windows NT Server does non back up promiscuous manner. Therefore, it can capture merely packets sent to the waiter or to all Stationss. ?
But?
Windows NT Online Help for Performance Monitor says, The Nework Monitor agent collects statistics from the computing machine? s web adapter card by seting it in promiscuous manner. ?
