sudo yum install percona-toolkit
.. rubric:: Generating an instance UUID for statistics
During the installating process, the percona-toolkit installer records a unique
identifier specific to the given percona-toolkit instance. This ID is a the
product UUID stored in |product-uud|. The installer copies the product_uuid to
|toolkit-uuid|.
This unique identifier is used when collecting statistics about the usage of
percona-toolkit. Note that no other information is gathered for this purpose.
In cases when the installer is not able to read the contents of
|product-uuid|, a random UUID is generated. A random UUID is
also generated if percona-toolkit is run from the binary in the *tar.gz* file.
