Hello all, I'm currently measuring my electricity usage using an counter - each time the meter flashes 1/800kWh, the counter value is put in the database. As it's a 32 bit integer, I've set the known limits to be 0 - 4,294,967,297 in the database. Thing is, if the counter resets to zero due to the sensor recording program restarting, the database assumes I've gone all the way to 4,294,967,296 and then back again, causing a huge spike showing I've used 228GW in 1 min. Now all of my graphs all the way up to the yearly graph shows that spike, and it's likely I'm not able to see anything until a year later - is there a way to prevent this? Should I not put in a known upper limit, but rather, putting in an "U" - will this fix it? Am I able to remove the errant data out of the database, or will I need to re-create the database?
Thanks for your time in advance! Regards - Piers _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
