Are you saying that (--global="routers.cgi*Options[_]: scaled nopercentile") 
will work to turn it off per target after it is turned on in routers2.conf.

If that is true I would need to redo all my configs prior to turning this on.  
I only want to test it on a few devices as starters.


Thanks for getting back.

Subject: RE: Using 95th percentile with mrtg configs

Routers2 allows you to selectively turn off calculation of 95th Percentile and 
Totals on a per-target basis using

routers.cgi*Options[]: nopercentile
routers.cgi*Options[]: nototal

You need to first globally enable the total/percentile module in the 
routers2.conf, though, by using the directive:

percentile = yes

There is not currently an option to selectively turn it on, because of the way 
the calculation module is linked into the code, but you can use a global 
default (as in your example) to globally disable and then selectively enable if 
you want. Originally this module was computationally expensive, but currently 
this additional loading is minimal due to improvements in Routers2 and RRDTool.

The percentile calculations use the best RRA available; therefore you lose 
accuracy on higher granularity (eg, monthly graphs).  You can fix this by using 
the RRDRowCount[] directive, or RRDRowCount2h[] (if you have MRTG 2.16.4 or 
better) to set the row count to 9600 or better (this only affects NEW RRD 
files, with existing RRD files you'll need to use rrdtune to expand the first 
RRA to have the same effect)

I am looking to try this but noticed that it is a variable in routers2.conf 
that need to be turned on. If I under stand this correctly this will have a 
global effect on all my current configs, which at the present is something I 
don't want. Is there a way to turn this option on in cfgmaker ?  Would it go 
here ? (--global="routers.cgi*Options[_]: scaled percentile")  I believe that 
this can be used to turn it off if it is on in the .conf file.   This is how I 
understood it from reading your first edition of Using MRTG with RRDtool and 
Routers2?
