Hi all,

I install PBM v1.8. The following are my server config.  
server 1: mongod 27018, config server 27019, mongos 27020  
server 2: mongod 27018, config server 27019, mongos 27020  
server 3: mongod 27018, config server 27019, mongos 27020

All three servers are in the same shared cluster, shard 1; This is a PSS replicat set.  
The purpose is: if necessary, we can add additional servers and create new shared cluster.

After I install PBM 1.8 with rpm package. There is only one pbm-agent.service on each server.  
When I started pbm-agent, the instance could only connect to mongod or confi server on each server. So, the pbm status command show incorrect status. What I do is to create a pbmconfig-agent.service to access config server process. It looks work.

My question is: Is there a way to connect both mongod and config server by one pbm-agent service?

Thanks,  
Dillon

Hello, currently PBM does not support backing up multiple mongod instances running on the same server. Feel free to open a feature request in [jira.percona.com](http://jira.percona.com) though.

Hi Igroene,

Thank you for reply. So, in current version, I can only create a sperated service manually to connect to config server in my case. Am I correct?

Thanks,
