That's because of the unison_tolerance setting in your smokeping configuration. http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html unison_tolerance if a graph is more than this factor of the median 'max' it drops out of the unison scaling algorithm. A factor of two would mean that any graph with a max either less than half or more than twice the median 'max' will be dropped from unison scaling The 30-hour graph is only showing 'properly', because the spike in your median rtt means that the rest of the smoke doesn't need to be chopped off. Once you zoom in on the 30-hour graph, so that you remove that large spike, then you'll see that it goes back to cutting off the smoke again. If you want to have it so that all the smoke is visible, then you just need to set a [much] higher unison_tolerance setting in your smokeping configuration file.
