Hi George.

I guess that there is a upper limit, but I don't think you reach it ;)
I'm doing similar graphs for 166 nodes, with 4 DS for each node
(CPU stats: user,nice,system,idle) without any problem
(using rrdtool 1.2.12 - yes I know thats old ;).
(This includes several CDEF statements like sorting out unreachable nodes, =
etc. )

Whats puzzling me are your strange (at least for me) looking
DEFs. e.g.:

DEF:1aggminclient_requests=3Dsql//RRDValue/UnixTimeStamp/value/RRDKeyID=3D5=
057/derive/:value:MIN

Whats these sql thingy? Do you store your data in an SQL database ?
If yes, maybe thats the problem. I'm storing my data in plain rrd files.

HTH,

Andreas.
