Hello,
We have a 100 node cluster and which is monitored by Ganglia .We are facing
some issue on the setup as below.
Here is the details
Three group cluster group created which is monitored by three multicast IP
APP_CLUS 239.2.11.71 10 NODES
DB_CLUS 239.2.11.72 80 NODES
SUP_CLUS 239.2.11.73 10 NODES
Once I have started the gmond service in all the 100 nodes ganglia web page
will show all the node status properly .
After exact 5 mins from DB_CLUS 70 nodes will say dead and critical .But node
is up and running:( .Changed all the configuration multicast IP everything but
result is same .
If I restarted the gmond in all the nodes again same issue will come after 5
mins.
Is there any limitation in multicast IP or ganglia ? We have a 20 node cluster
which is working fine without any issues .Only one difference between these two
setup is 100 node cluster is running in DNS and 20 node cluster is with local
host names.
Thanks & Regards,
Sarathchandran
