performance

  1. Performance Counters

  2. Data Performance Counters

  3. Web Performance Counters

  4. Data Readers

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of performance monitoring in web applications.

Option A) Performance Counters - This option is correct because performance counters are a feature of the Windows operating system that allows you to monitor various aspects of system performance. Performance counters can be used to obtain performance information about a web application, such as CPU usage, memory usage, network traffic, and disk activity.

Option B) Data Performance Counters - This option is incorrect because there is no specific term called "Data Performance Counters." It is likely a combination of two different concepts - "data counters" and "performance counters."

Option C) Web Performance Counters - This option is incorrect because although "Web Performance Counters" sounds related to web applications, it is not a commonly used term or feature. Performance counters are more commonly used for monitoring system performance rather than specific web application performance.

Option D) Data Readers - This option is incorrect because "Data Readers" is a term typically used in database programming to read data from a database. It is not directly related to obtaining performance information about a web application.

The correct answer is A) Performance Counters. This option is correct because performance counters are commonly used to obtain performance information about a web application.

This is the most important measure in dealing with performance issues.

This tool in Oracle10g defaults to a collection interval every 30 minutes and collects data that is the foundation for all of the other self-tuning features. It is very much like STATSPACK, especially the level-5 STATSPACK collection mechanism where top SQL is collected every hour, based on your rolling thresholds for high-use SQL.
