# apt purge service-discover-agent
# apt clean
# apt autoremove

Please don't worry about being complaining 😊 A healthy discussion could clear doubt from users mind and provide us improvement points. The package service-discover-agent exists in the monitoring role, may bee that's why it got installed in the system.

The roles description and installation processes are explained individually, therefore you can see each role installation has service-discover-agent package. But the key facts are:

  • If you are installing all the roles on the same server/node along with service-discover-server package, you do not need to install service-discover-agent as service-discover-server can be both server/agent.
  • If you are installing few roles on the same server/node where service-discover-server does not exist, you can install service-discover-agent once but not for all roles individually.

Hope it helps.

Regards,

thx thx - but may i ask?  i do not recall installing it specifically.  i do recall following this link to install the monitoring.

https://docs.zextras.com/carbonio-ce/html/install/roles/role-monit.html

i either mistyped one of the commands/steps, or maybe there is some error in the steps?

not complaining, but just flagging my steps.

thank you all again for your help.

Installing both of them in the same node would create conflict.

Regards,

Oh, I saw you installed both service-discover-server and service-discover-agent. The conflict might be that service-discovery is not starting the service. Please remove the service-discover-agent installation package in the following order and restart the service to see service-discover:

# apt purge service-discover-agent
# apt clean
# apt autoremove

Please check if the service-discover service is running?

# systemctl restart service-discover

Could you please show me the output of the following command?

dpkg -l | grep service-discover

I think the problem lies with the service-discover service not running, and I believe reading the journal logs would provide some clues about the error.
If fixing service-discover is not effective, you might consider deleting the MESH data and reconfiguring it. Before deleting the MESH data, I think you should have a backup plan.

systemctl stop carbonio-service-discover
rm -rf /var/lib/service-discover/data/
systemctl start carbonio-service-discover


After deleting, you can reconfigure it as published on the Carbonio homepage:
