OK, that makes sense. So a follow-on question: if I define thresholds in the central hub collectd, do all thresholds apply/check every sixty seconds, or do they "do the right thing"? If I happened to have it the other way around (leaves update each minute, hub updates even ten seconds), I can imagine the thresholds all freaking out (when $Important is set) because they haven't seen an update for five intervals (50s)... (BTW, thanks for the fast responses :-) _______________________________________________ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd
