[rrd-users] Newbie question

[Bill Ryan]

Apology for the relative newbie-ness of the following:

Simple graph, GAUGE MAX, Sun server CPU loads (uptime) gathered only once 
every 15 minutes.  The loads average ~ 0.5 -> 4, but occasionally will ramp 
up well into the hundreds - indicative of severe NFS I/O and eventual server 
failure if not caught in time ...

Anyway, what I need is a database which will have true values (unlimited 
upper boundary) but will graph, say, 0 -> 50, so the typical range of data 
will be viewable - but when the load spikes to past 50, rrdtool will not 
consider it an anomaly and will show the spikes only as topping out the 
graph.  IOW, "-u 50" nicely keeps the graph between 0 -> 50, but removes the 
spikes that go beyond ... and I need this information represented as well.

Any help, thx.
