pmm-admin add mysql - invalid username or password

Percona Monitoring and Management (PMM) PMM 1.x
1

Hello,
I’m trying to add mysql monitoring:
sudo pmm-admin add mysql --query-source=perfschema --username=XXX --password=XXX --debug

Username/password are correct, I can login to mysql locally, to 127.0.0.1.

But I always get: “Invalid username or password. Please check username and password.”

Is there any special mysql role I need to add to the user? Or may be there’s some firewall issue I’m not aware of?

​​​​​​​Regards​​​​​​​

Hello, could you check your CREATE USER statement for pmm? PMM2 is sensitive for difference between localhost and 127.0.0.1
For example my pmm_user statements are:

CREATE USER pmm_user'@'127.0.0.1 IDENTIFIED BY pmm_password;
GRANT SELECT, PROCESS, SUPER, REPLICATION CLIENT, RELOAD ON *.* TO pmm_user'@'127.0.0.1 WITH MAX_USER_CONNECTIONS 10;
GRANT SELECT, UPDATE, DELETE, DROP ON performance_schema.* TO pmm_user'@'127.0.0.1;

Added these grants, still doesn’t work. Debug output is the following:

As I can see you are Unauthorized on pmm-server side. You need to specify admin user and admin password from PMM Server on config stage.

pmm-admin config 10.10.10.10 generic best_db_name --server-insecure-tls --server-url=http://admin_user:admin_apssword@pmm.com/

Ok, I got this working! In PMM Inventory I can see MySQL service. But nothing is displayed in mysql dashboards :frowning: Been trying to find next steps in online docs/blogs, but couldn’t.

could you share output of?

pmm-admin list

Also you can open url, but you should be logged in as admin.

your-pmm-server-domain.com/prometheus/targets

There you can find all connected agent to PMM Server and their status. It can provide more information.
