on the rrdtool-user mailinglist i learned that unknown values were indicated to rrdlib with the char "U". Now, that i set unknown values in my plugin to "U", i get this error in the logs:
Argument "U" isn't numeric in subroutine entry at /usr/share/perl5/Collectd/Plugins/OneWireCtlr.pm line 135 - which is the line plugin_dispatch_values(\%v); so please help me out, how do i tell collectd that a value is unknown, and should be teated as such?
