Hi,&nbsp;  
Good Day. Today I have installed pmm2 on docker. I have add client with below command. But no client showing on MySQL Instances Overview and PMM Home Page. Would you please help me on this.&nbsp;

Hi @shohaghbd   
Basically you have to add monitoring service after configuring client with server.  
pmm-admin --config&nbsp;&nbsp;  
and  
pmm-admin --add&nbsp;  
  
–config =&nbsp;Connecting PMM Clients to the PMM Server

–add = add MySQL service to monitoring&nbsp;

did you face any issue while performing above steps?

Since pmm-admin list is showing a stuff running on the node I’m going to assume you DID run the pmm-admin add command.&nbsp; One thing that can be tricky (which we are working fixing!) is that you can register a pmm-client to a server and make an outgoing TCP connection on 443 and get success BUT that registers the client with the server, fires up the exporters on the local ports of 4200x (42001,42002 in your case) of the client and instructs the PMM server to make a connection TO those ports on the client and that’s usually where things break. I’d go to the host for your pmm server and see if you can telnet from 192.168.20.2 to 102.168.20.4 on port 42001 (‘telnet 192.168.20.4 42001’ gonna guess no) so you would need to look at UFW or iptables or another firewalls that could be interfering.&nbsp; You can also get a better idea by looking at [https://192.168.20.2/prometheus/targets](https://192.168.20.2/prometheus/targets) to see if the “unhealthy” targets are complaining about no route to hose, connection timeout or context time exceeded…all of which point to networking getting in the way.&nbsp;  
  
When we finish fixing we _should_ be able to do everything over the client–\>server tcp/443 connection so if you can register your node you WILL get data!&nbsp; Don’t have an ETA for a release yet but designs are all done, scope’s defined, just need it worked in with the rest of the priorities (it’s high, but not at the top).&nbsp;

You just configure pmm client which enable only node monitoring. If you want to monitor **mysql** , **mongodb** , **postgreSQL** further then you need to add these services for monitoring like below:  
`pmm-admin --add`
