Nagios Support Forum

Hi, is any chance to set accuracy in nagios XI graph's? My service returned only integer but on the graph nagios shows float.

This is a result of how RRDTool collects data. Unless the step and time are 100% in sync which never happens you will get floating point. RRDTool interpolates data to calculate what the data would be on the defined step. I was looking for a better explanation/tutorial that I'm sure I read one somewhere a long time ago but I could not find the one I was thinking of but found this instead. This picture shows how RRD interpolates two values 7 and 10 taken 310 seconds apart in a round robin db with a 300 second step size. Image and discussion from http://forums.cacti.net/about33897.html
