Tobi, well.... i feel a little stupid. i guess my misunderstanding of the hw algorithm shows here, but in formulating my answer i found that devpredict was getting filled out properly. i've upped a graph from the rrd so you can see what my problem was:
http://www.feltonline.com/p_c/example.png it would appear that i didn't have enough data for hwpredict to kick in? the last graph that i'd created was before it picked up at about 21:30 last night. it was then that i really started trying to research the problem and joined the list. pat Tobias Oetiker wrote: > Today Patrick Felt wrote: > >> i've been having problems with hwpredict. the devpredict rra shows as >> nan all the time. in researching what i've done wrong i found this bug: >> >> http://people.ee.ethz.ch/~oetiker/webtools/rrdtool-trac/ticket/8 >> >> a note at the bottom, added by tobi, says: >> -------------snip---------------- >> The problem seems only to occur when running several updates in one >> round ... when calling rrdtool updatev once for each number then all is >> fine.
