In general upsc will show driver.parameter.pollinterval: 1 that's on bestfortress that I set to 1 instead of 2. As to whether all params are received every poll interval, good question and I'd read the source, but just log and plot for a while and it should be easy to tell. Utility voltage likely varies over daily timescales, seconds due to big loads and ms-level due to faults. The latter is basically not observable with nut monitoring. I've been logging this, but I log once/minute and also once/second log only if the data is interesting relative to last log. This is to get prompt monitoring detection of low (as in 0) line voltage. _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
