Hi all,

When issuing the command:

pmm-admin add mysql --user pmm --password blah

has anyone seen the error:

[linux:metrics] OK, already monitoring this system.  
[mysql] 2017/03/09 18:13:28 packets.go:33: unexpected EOF  
[mysql] 2017/03/09 18:13:28 packets.go:124: write unix @-\>/var/run/vividcortex/vc-mysql-metrics\_20/ipc: write: broken pipe  
[mysql:metrics] Cannot connect to MySQL: driver: bad connection

The pmm mysql user does has the correct privileges.

thx

Hi booger,

is command working fine?  
can you add option with correct path?

like

```auto
pmm-admin add mysql --user pmm --password blah --socket /var/lib/mysql/mysql.sock

```

can you show output of command?

Hi Mykola, adding the socket worked.

Thanks
