Description:

I have the ping plugin configured for collectd, and while the updates to the RRAs for the ICMP RTT & Drop Rates are updating correctly, the Standard Deviation graph shows only 0.0 for all times. I even checked the rrd files use rrdtool dump and all the values in the RRAs are set to <row><v> 0.0000000000e+00 </v></row>.

Nevermind, I figured out the issue. My configuration for the ping interval was wrong. It was set up so that only one ping was being sent per data collection round.
