[smokeping-users] Re: Clearing extreme points in graphs?

[Dan McGinn-Combs]

There is a tool in the CONTRIB directory of the RRDTool distribution
called  KillSpike which, uh, will kill those nasty spikes.

I only found it in the "real" distiribution, however, it does not show
up in the x86 zip files. It is, however, a perl script.

As smokeping is using rrdtool you should be able to specify min and max
during creation

 rrdtool create filename [--start|-b start time] [--step|-s step]
[DS:ds-name:DST:heartbeat:min:max] [RRA:CF:xff:steps:rows]

But as far as I can see this is not settable via the confif file.
