First, we'll describe the basics of what Linux logs are, where to find them, and how they are created
Linux System Log
Many valuable log files are created automatically for you by Linux. You can find them in the/var/log directory. Here's what this directory looks like in a typical Ubuntu system:
Some of the most important Linux system logs include:

As we all know, orion comes with oracle, but it is only available before 11.1 on the Internet. It is not powerful enough. What if I/O testing is required and the local machine does not have oracle? I can only find another method. Here is a good method to recommend to you:
First, we need several packages:Find the libclntsh. so.11.1, libcell11.so, libskgxp11.so and libnnz11.so packages in the $ ORACLE_HOME/lib directory.
Copy these packages to a linux d

/Var/log/wtmp or/var/log/utmp-contains logon information. Using wtmp, you can find out who is logging on to the system and who is using commands to display the file or information.
/Var/log/faillog-contains the User Logon Failure Information. In addition, the error logon command is recorded in this file.
In addition to the preceding log files,/var/log also contains the following sub-directories for specific system-based applications

Many programs need to record their actions. System programs usually write information to a terminal or a log file. This information may indicate errors, warnings, or more genera
some time ago, I saw MacLean Liu share a good article on Exadata I/O performance calibration: Calibrate Test Exadata IO, this article basically covers the exadata I/O performance calibration method. Just recently someone has asked me this question, so I will try to make some additions to the fish, there is duplication of places please ignore it.
If I/O performance calibration or testing is required on exadata, there are usually several methods:

Digital Ocean has a complete tutorial on these files that describes how rsyslog creates them in common Release versions such as RedHat and CentOS.
The application will also write log files in this directory. For example, common server programs such as Apache, Nginx, and MySQL can write log files in this directory. Some log files are created by the application, while others are created by syslog
