Hi,
I’m writing this mail to discuss whether Ganglia works well for a large-scale
cluster (more than 4000 nodes).
As per Ganglia document, ganglia can scale to handle clusters with 2000 nodes.
So many people have concern on using Ganglia for a 4000 nodes production
cluster.
It has been used to link clusters across university campuses and around the
world and can scale to handle clusters with 2000 nodes.
If the cluster is large than 2000 nodes, say 4000 nodes, can Ganglia handle it
properly?
To verify this, I create a 5000 nodes ganglia cluster on top of Docker cluster
(10 machine).
I put 500 nodes in a cluster, so there are 10 cluster. And these 10 clusters
are in the same Grid.
For each gmond, I use a script to generate 30 customized metrics (with
gmetric).
Currently it works fine in the Docker based test environment.
So, my question is whether Ganglia is suitable for 4000 nodes cluster?
Thanks & Best Regards,
Jason Gu0o
