deliberately truncating (capping) graphs

[atworkowski]

Could someone tell me the best way to acheive a truncated graph. What I am trying to acheive is to have the traffic graph (Interface - Traffic (bits/sec)) show only the bottow 10M of a 100M interface. Anything above 10M is ignored and the vertical index does not exceed 10M.

Thanks in advance.

Edit the graph template and set the max size.

You trying to ignore spikes?

[atworkowski]

Do you mean "Upper Limit"? I have tried this but doesn't seem to work.

Yes, I am trying to ignore spikes. I am interested in the traffic from the perspective of the external link (10M) and can safely ignore spikes from internal interface (100M interface).

Editing the template will work only for new defined rrds. To change existing rrds, please use rrdtool tune <filename> --maximum <ds>:<value> as described at http://www.rrdtool.org
