we did this on the main page for grids by adding one line of php that
excluded the bulk of our computing grid.

We also added a regexp parameter that you could pass in GET and
everybody used predefined view without ever hitting the main grid
page.

So for example you'd have http://ganglia.organization.tld/
?g...x...regexp=mysql.* which would only display all mysql servers.
Of course this means you rely on a naming rule that might not be true
for your environment.

 What are your thoughts on how we can accomplish this?

Probably best to look into the new frontend which is being built
exactly to address all this sort of limitations.

[Ganglia-developers] How do we deal with very large clusters in the webui

[Jim Greene]

Gents,
We are running into issues with having very large clusters in the webui.
Loading a cluster with 4,000 machines takes way to long, even with caching.
We would like to come up with a method to somehow automagically break up the
views into smaller chunks. Some of the thoughts on how to do this:

-Break up the fews into multiple pages per cluster. So you might only
display 500 hosts and hit next for more

-Don't show any individual hosts, only the aggregate and the
load/network/etc levels for the whole cluster

-Display only a certain subset of machines for a default view (based on
load, etc)

What are your thoughts on how we can accomplish this?

Thanks
