Hi,

While I’am starting the pmm-admin services, I am receiving the below error. What does this mean? did I missed something.

sudo pmm-admin start --all  
OK, started 2 services.  
Unable to connect to PMM server by address: XX.X.XX.XXX

Even though the server is reachable it does not look to be PMM server.  
Check if the configured address is correct. %!s()

can you check disk space inside PMM Server container?

Can you share the output of the following command?

```auto
docker exec -it pmm-server df -h

```

Mykola, my service is running on Linux machine, not in docker, could you please share the inputs related to CentOS?

$ sudo docker exec -it pmm-server df -h  
Error response from daemon: Container pmm-server is not running

Thank you.

PMM Server has only three ways to be installed:

- runs as Docker container
- runs from OVA image in VirtualBox and VMware
- runs from AMI image in Amazon.

How was PMM Server installed?
