In this practice, you use Performance Logs And Alerts to create a counter log and an alert for the free practice questions Searches/Sec counter.
Exercise 1: Creating a Counter Log
In this exercise, you create a counter log by first defining the counters you want to log ancl then setting log file and scheduling parameters.
1. Use the procedure provided earlier in this lesson to create a counter log named
LDAP Searches Per Sec for Serverl.
Select the NTDS performance object and the LDAP Searches/Sec counter to log.
Analyzing Performance-Monitoring Results The baseline you develop establishes the typical counter values you should expect to see when your system is performing satis?factorily. Use your baseline to detect when bottlenecks are developing or to watch for long-term changes in usage patterns that require you to increase capacity. A bottleneck is a condition, often involving a hardware resource, that causes the entire system to perform poorly. A bottleneck exists if a particular system component is keeping the entire system from performing more quickly. ...
... Therefore, even if a component in your system is heavily used, if other components or the system as a whole show no adverse effects, there is no bottleneck. Deviations from your baseline provide the best indicator of a bottleneck. However, occasional spikes in data might occur due to startup of a process and are not an accurate reflection of counter values for that process over time. Set alerts according to the counter values you consider to be unacceptable, as determined by your baseline.
It is not unusual to trace a bottleneck to multiple sources. Poor response time on a free comptia security+ exam workstation is most likely to result from memory and processor problems. Servers are more susceptible to disk and network problems. Also, problems in one component might be the result of problems in another component, not the cause.
Planning and Implementing Changes to Meet the Baseline If you identify a bottle?neck, you must investigate the activity of the associated resource in greater detail to determine what changes must be made. Your investigation should include the follow?ing considerations:
Analyze hardware and software configurations. Do these configurations match Microsoft recommendations for the operating system and the services you are sup?
porting?
Review the directory service log for the time period when you begin seeing out-of-range counter values. Do any of the entries in the log provide information on
problems which could cause a bottleneck?
Examine the kinds of applications you are running and the resources these appli-cations require. Are the resources adequate?
Consider network or disk utilization or other activities occurring at the times that you see increasing resource utilization. Try to understand the usage patterns. Are they associated with specific protocols or computers?
Consider variables in your workload, such as processing different jobs at different times. What work is being done by the system?
Approach bottleneck correction in an organized manner. Never make more than one change at a time, always repeat monitoring after a change to validate the results, eliminate results that are suspect Free A+ exam questions, and keep good records of what you have done and what you have learned.
