Category:	MySQL Enterprise Monitor: Installing	Severity:	S3 (Non-critical)
Version:	2.2.0.1709	OS:	MacOS
Assigned to:	BitRock Merlin	CPU Architecture:	Any

Description:
The installer asks for root credentials, even if you say you have already created the account.

'Re-enter :' prompt looks like it has problems as well.

See the output below.

These steps are not covered in the 2.2 installation in the manual either. I think there have been some other text changes as well.

Monitored Database Information

Agent User Account Creation

To monitor your MySQL server, the Agent needs a user account with special privileges. If you provide the login credentials for the root account below, we will use those to create your Agent's user account for you based on the user account credentials you entered on the previous screen.

Note that the root login credentialls will only be used to create the Agent's user account, they will not be saved.

[1] Yes, use the credentials below to create the Agent's user account
[2] No, I've already created the account and I'm sure it's correct
Please choose an option [1] : 2

Root Username [root]: blah

Root Password :

Query Analyzer Configuration - Proxy

The MySQL Proxy enables the Query Analyzer by listening on specified ports for connections from client applications, collecting data from those connections, and passing that data on to the Service Manager.

Visit the following URL for more information:
https://enterprise.mysql.com/docs/monitor/2.2/en/mem-qanal-using.html

How to repeat:
Do a 2.2 agent installation from scratch (not an upgrade) in --mode text on Max OS X (probably linux as well).

Suggested fix:
Fix the installer script to not ask for the root credentials if not needed (or explain why it is needed).

Update the agent installation in the manual with the new text and added step.

Patch sent to Andy.

A note has been added to the 2.2.3 and 2.3.0 changelogs: 

        The &merlin_agent; installer would ask for agent credentials,                                                                                      
        even if you had indicated that the correct user credentials                                                                                        
        had already been created.
