Dear Jesse,
How does one split a cluster to separate ones, to display in a single
Gangnlia-Web instance? Also, is there a way to make some of the clusters
private, like they do on SurfSara? https://ganglia.surfsara.nl/
I mean there is a way since its been done, but could anyone suggest how
exactly? Thanks!

There isn't a way to do it natively, but there are a few ways to work
around it.
One is to split your hosts into separate clusters, and multiple gmetad
instances. These could easily be on the same host, but use different
disk partitions so there's less IO contention.
Dump all of the files into a single location, but use symlinks to
distribute them.
Get an SSD drive, and use that; it should help a fair bit since the IO
is largely small/random.
Disable readahead on the device in question.
Use tmpfs to store the RRD files, but remember to sync them back to
persistent storage periodically (and restore them again at boot-time).

At the moment all of my rrds are going to the host which hosts the
gmetad.
Is it possible to split the gmetads to different hosts so rrds will be
distributed? I am asking this because I am monitoring 400 hosts and
having
I/O disk wait problems. I would like to split the load.
Any thoughts?
