Hi, I hope this is not too much of an FAQ: I'm using rrdtool to graph the temperature readout of a sensor. The step of the DB is 60 seconds (to get a high resolution), the cronjob runs every minute as well. RRA looks like this: RRA:temp:GAUGE:600:U:U RRA:AVERAGE:0.5:1:2880
Unfortunatly, that sensors is sometimes slow to respond and returns no value, in which case my scripts returns "U". This is an example of what is written with rrdupdate: 25.4 U 25.4 25.4 After this, the RRD itself contains this 2.5381565507e+01 1.0256079733e+00 2.0670413320e+01 2.5400000000e+01 That creates an "ugly" spike in the graph. What is the recommend way to make sure that an unkown value does not have such a huge impact? Basically I'd like values written to the RRD as unknown to be ignored or interpolated from valid data before and after the unknown readout. Thanks. -- Fridtjof Busse _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
