Hi Clint, You need to configure the datastax-agents so they know what machine OpsCenter is running on. To do this you will need to edit the address.yaml of the datastax-agent, located in /var/lib/datastax-agent/conf/. In this file you need to add the following line:
stomp_interface: <opscenter-ip-address> This will allow your agents to connect to the OpsCenter server (opscenterd) over the stomp protocol (stomp.github.io/). For a more detailed look at the configuration options available to the datastax-agent see this page: datastax.com/documentation/opscenter/5.0/opsc/configure/agentAddressConfiguration.html Mark On Fri, Aug 15, 2014 at 3:32 AM, Clint Kelly <clint.ke...@gmail.com> wrote: > Hi all, > > I just installed DataStax Enterprise 4.5.
