Unable to monitor mysql queries with 1.0.4

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

Hello, I have installed 1.0.4 and then tried to add a client.
I get this error

pmm-admin add mysql --user=root --password=mysql-password
[linux:metrics] OK, now monitoring this system.
[mysql:metrics] OK, now monitoring MySQL metrics using DSN root:***@unix(/var/lib/mysql/mysql.sock)
[mysql:queries] Error adding MySQL queries: cannot find os instance on QAN API.

I had an old installation of PMM 1.0.3 that I removed.
I have installed the client using the yum repository; the client is running on percona server Percona-Server-server-56-5.6.28-rel76.1.el6.x86_64 on centos 6

Hi, Could you please clarify if you have just reinstalled the client or have you reinstalled the docker container for 1.0.4 from scratch as well ?

Hello,

Looks like the old client 1.0.3 was not uninstalled using uninstall script.

To fix the problem, just run:
rm -rf /usr/local/percona/qan-agent/{config,data,instance}

And re-run “add” command.

Peter, I reinstalled both client and server container.

weber, it worked … thanks a lot.
