The data collected by the Database Analyzer during the day is saved in a range of log files in the log file directory.
You can specify the log file directory as follows:
When you call the Database Analyzer, you can use the option –o to specify the log file directory. The log files are saved in the subdirectories /YYYYMMDD.
If you start the Database Analyzer on the computer on which the database instance is installed, you do not need to specify –o. The log files are saved in the subdirectory analyzer in the run directory of the database instance.
The Database Analyzer generates the following log files:
This file contains the following information:
· Unique information about the configuration and performance-relevant data of the database instance
· Bottlenecks discovered by the Database Analysis during each measurement
The Database Analyzer weights the information and bottlenecks:
I |
Information |
General information, such as the number of executed commands |
W1 to W3 |
Warning levels 1 to 3 |
Bottleneck warnings with low, medium, and high priority |
E |
Emergency |
Critical problems, such as an imminent database crash |
These files contain all analysis data. They allow you to check runtime behavior retrospectively.
One file exists for each monitor class (analysis area). You can use Microsoft Excel to open and read this file as soon as the Database Analyzer stops writing to it.
