three mysql instances are monitored,but the buffer pool size of total ram has no data

I monitored multiple mysql instances on one server:

Pmm-admin add mysql --user PMM --password PMM --socket= XXX 1.1.1.1-3308

Pmm-admin add mysql --user PMM --password PMM --socket= XXX 1.1.1.1-3309

Pmm-admin add mysql --user PMM --password PMM --socket= XXX 1.1.1.1-3310

And add Linux :metric

PMM - admin add Linux: metric 1.1.1.1

Now there is no data in the buffer pool size of total ram in the mysql overview of the monitoring interface. Does the mysql instance 1.1.1.1-3308 need to read the data of Linux :metric 1.1.1.1-3308? But what I added is the data of Linux :metric 1.1.1.1?

I tried to add more Linux :metric X.X.X.X, but the system could only add one.How can you make buffer pool size of total ram of multiple instances display data normally
