One of Archive's clusters, more or less:
1700 hosts, 512-1GB RAM mostly, 1T to 4T of disk per host
Wishlist additions and seconds:
- 4T Memory limit (already mentioned)
- Multi PB disk limit
- Better on disk RRD perf (tmpfs is an OK workaround)
- Better support for bigger less frequent updates (

Hi Bernard,
I'm using Solaris 10 Sparc and x86. The hardest hit gmetad host runs
Solaris 10 x86 and is monitoring around 1000 systems. The system takes
a good minute to offer a shell via ssh and the I/O subsystem is
completely saturated. The RRDs currently live in a boring old UFS
filesystem an

Not sure if anyone would find this helpful, but this looks pretty damn useful:

take a look there, he's got some javascript which will show you the values as
you move
Perhaps it's time to migrate all existing RRDs that store byte counts or
their derivatives to 8 byte ints?

Hi Carlo:
Thanks for doing this.
I guess I should subscribe to the -commits and -bugs mailing-lists so
I can be more on top of development...
Cheers,

I would love to see the 4T memory limit removed.

As far as I understand it, the compatibility issue is mostly between gmond and
gmetad rather than RRDTool. The consequence is one would have to upgrade all
of a site
- graphs of metrics aggregated at the grid-of-grids level, when a gmetad
instance is polling other gmetads. I have some basic code to contribute on
this front but like the stacked graphs, it could use a production-quality
scrubbing.

Great list!
As to compatability breakageit would suck to lose data, for sure. So how
about
maybe adding a way to possibly archive past data ? Possibly freeze the data you
have
before upgrade, and then have it available as a separate item, just never to be
updated again ?

Hi all,
Following on from Bernard's & Brad's emails, here's my wish-list for 3.1.0
(although some ideas are perhaps for a more longer-term).
