Hello! Can you explain in greater detail how you are using the One-Wire plugin for Collectd? According to their site it can read the database that RRD creates. And it further explains how contributed material can create graphs. But outside of that, I need more information to best make up my mind. ----- Gregg C Levine gregg.drw...@gmail.com "This signature fought the Time Wars, time and again."
