<pre wrap="">LSL trending is only good for trending linear data. I have trend lines on all my graphs by default and find them useful even when the data is not linear.
If the data you are trending is total MB in the last 30 days until you get over 30 days of data the trend will be invalid.
Vnstat is great and setting an hrule from the estimate is a great idea. If it were me I would still put a LSLTrend line on the graph just as an aid.

Does anyone know or understand the algorithm vnstat uses to do its
prediction?<br>

Subject: [GRAYMAIL] Re: [rrd-users] RE: RE: Question about trend line
Thank you again for great explanation. My graph shows total consumed data on
WAN0 interface, so not units/sec but total Megabytes that went over this interface in range of 30 days.
Reading all this about LSL* I think I should maybe reconsider using LSL functions here and find another way of predicting.
vnstat linux tool gives me prediction that if far different than LSL* ( 9.81 GiB currently is predicted whereas LSL gives almost 12GiB.)
Maybe using HRULE and the predicted value from vnstat would be a direction.
