Dear @soprano
I created a task in Jira to fix a bug in the documentation
https://jira.percona.com/browse/PXB-2169
You can sign and receive a notice of correction.
@Satya thank you for your help
P.S. Perhaps you will be interested to become a contributor to this project and fix the bug in the documentation yourself. We have instructions on how to contribute to Percona documentation. https://www.percona.com/community-blog/2020/01/28/how-to-contribute-to-pmm-documentation/.
