Re: [Ganglia-general] Gmetad-to-Gmetad connection
Hi Vladimir, I changed to “scalable on”. I didn’t help. What I see is only the common remote grid view: CPUs Total: 120 Hosts up: 16 Hosts down:2 == Current Load Avg (15, 5, 1m): 3%, 3%, 3% Avg Utilization (last hour): 4% Localtime: 2015-03-25 10:27 === I can’t see any clusters and hosts inside this grid. By netstat I can see that the second Gmetad instance on machine2 periodically connects to the machine1:8651. I don’t see any connections to machine1:8652. The second Gmetad instance has the same ports, but it’s on another machine. Did you mean that it can affect the polling process? Any ideas? Thanks!

I changed the second Gmetad to scalable off” and it works! Thank you! Sergey On Mar 25, 2015, at 1:48 PM, Vladimir Vuksan vladi...@vuksan.com wrote: I might have misspoke try scalable off.
