after moved cassandra from endpoint_snitch: SimpleSnitch to PropertyFileSnitch
at the startup of tarball opscenter I get in opscenterd.log:

WARN: HTTP request http://172.17.4.26:61621/cluster/datacenter?node_ip=172.17.4.26 failed: Connection was refused by other side: 111: Connection refused.

opscenterd.conf
================
[webserver]
port = 8888
interface = 172.17.4.26
[logging]
level=DEBUG
[agents]
use_ssl = false

cassandra-topology.properties
=============================
172.17.4.26=DC1:RAC1
default=DC1:RAC1

at this stage there are no agents (still waiting for agent.tar.gz to be created ..)

ynixon,

That warning is just informing you that OpsCenter cannot connect to the agent on that node, which makes sense if there are no agents running yet. Once the agent is installed and running, OpsCenter will connect and begin collecting node metrics.

Cheers,

Thomas

From the documentation I understand that the first time opscenter is started, a file called agent.tar.gz should create automatically
at some former installations it happened and somehow it is not happening anymore :(

After some reading I understand that this file can be created by running bin/setup.py

should I relay on the automatic way or manual way ?

ynixon,

opscenterd will only create agent.tar.gz if ssl is enabled (it is by default), and setup.py has not already been run for that instance. It should be something that you only need to run once.

You can look in opscenterd.log for messages starting with "Configuring agent communication". That will let you know if SSL is enabled or not. If it is, and bin/setup.py is going to run, you'll see another log message that says "SSL files do not exist. Attempting to create them now....".
