In addition to describing the level of detail and what hosts/components/resources you want to compare, if you are comparing a host to a model in the repository, or if you are simply comparing two directories on a host, you have the option of defining sets of files or directories to exclude from a comparison. You might want to do this if you know for certain that certain resources have many differences that are not important to you. You can save these definitions and reuse them in other comparison definitions.
To specify directories or files to be ignored, do the following:
Enter the name of the directory or file you want to ignore, or provide an expression to represent the directories or files you want to ignore using wildcards (*).
For example, if you want to ignore all log files, you can specify *.log to be excluded.
You must specify a complete pattern (with or without wildcards) all the way to the file name; simply specifying down to the directory level will not exclude the files in that directory unless you add a * to the end. For example, if you want to exclude all the files in /usr/apache/logs, you must specify /usr/apache/logs*
Click add.
Your specification will be added to the bottom of the list of directories and files to be ignored.
The ignore box is checked by default to mark this directory or file so that it is not included in the system comparison.
If you want to remove this exclusion rule in a future comparison, you can uncheck the ignore box.
