## Description:

Monitoring 8 servers and all have N/A in the MySQL /MySQL Instance Summary/Buffer Pool Size of Total RAM

## Version:

PMM 2.42.0. Used the Quick start guide to install on Debian 10/11/12. Running Percona MySQL 8.0.33

## Expected Result:

Show Buffer Pool Size of Total RAM on the MySQL/MySQL Instance Summary.  
The correct memory does show on the Home/Dashboard, just not on the MySQL screens

## Actual Result:

Shows N/A

Hi @jknight,

Do you have both OS- and MySQL-related metrics working for these nodes? What do you get from the following command run in one of these client nodes?

```auto
pmm-admin list

```

It may be a bug with current versions, but first it would be nice to check if you are indeed having all available metrics needed for it to work. I can spin up a test instance after we can validate this.

Yes I have both metrics working for these nodes.

Here is the results from pmm-admin list on one of the nodes
