If you'd post the code, I'd appreciate it. I'm fairly new to perl and even newer to rrdtool, so I can use all the tutelage I can get. Do you incorporate it with 14all or something, or does your script build the graphs too? Sorry if that's a stupid question...

I compute 95th percentile for customer bandwidth. Accuracy will depend on the number of sample interval and number of samples. I don't use the default mrtg-like definitions. If you use the Statistics::Descriptive perl module, it's pretty simple. I do a fetch of the interval I wan't to compute over (in my case, it's 5 minute samples for the last 30 days). I can post the actual code if you like, but essentially: $stat = Statistics::Descriptive::Full->new(); ($start,$step,$ds,$data) = RRDs::fetch .....; foreach (@$data) { # # Substitute zero for missing samples if ($_->[0] eq "" || $_->[1] eq "") { $sam = 0; $drop++; } else { $sam = ($_->[0] * 8) + ($_->[1] * 8); } $stat->add_data($sam); } $perc = $stat->percentile(95); On Wed, 14 Mar 2001, Mike Bernhardt wrote: > > This question has been asked several times before, but I haven't seen any > answers- has anyone come up with a script to generate 95th percentile?
