0 connected nodes in datastax opscenter

  • 772

Installed opscenterd on the separate node outside of the cluster, but within firewall ( aws security group ). Tested all possible ports between agents and opcenter server. No errors in the log..

2013-10-30 01:07:23+0000 [FC_Cluster]  INFO: Initializing event storage.

2013-10-30 01:08:04+0000 [FC_Cluster]  INFO: Agent for ip 10.34.10.185 is version u'3.2.2'

2013-10-30 01:08:04+0000 [FC_Cluster]  INFO: Agent for ip 10.82.226.252 is version u'3.2.2'

The most interesting part that I can see some data in the opscenter UI, when I stop agents, there is no data displayed, when I start - it show up again, but at the same time it shows 0 connected nodes. Storage capacity is even funnier - 3 of 0 nodes..

Any ideas why that could be happening?

    The push/stomp connection between the browser and opscenterd is broken. You can see this by the disconnected plug icon near the top right.

    Assuming you're still using nginx proxying, try turning proxy_buffering off. Other users have had success with this in the past.
