Please explain poller.php output

[kbartoletta]

Sorry, but can someone please briefly tell me what I am seeing here

What does the "u:3.86" "s:1.13" and "r:259.27" refer to?
What are the "Waiting" messages?

Many of the moderators are quite busy including myself. Many others know the answer. You are correct, it is a shame. The results are STDOUT from RRDtool and the "Waiting on" is poller.php
