RRD Graph Percentile Change

[craigduff]

Is it possible to change the 95th Percentile option for the RRD Graphic? to show 90th Percentile instead?

Not easily.

you could go into /usr/local/www/status_rrd_graph_img.php and make some edits to change 95 to 90 on lots of lines, and hope it works. (Though some may also need to change 5 to 10)

Unless you know your way around rrdtool syntax, it's probably not something that should be attempted lightly.

Fair play! Thanks alot. Could it be worth putting it in the suggestion for future releases?

Jimp this is the bit I have changed. And the Graph is working and now says 90th Percentile, but im not 100% sure if its calculating it correctly. Can you confirm?

$graphcmd .= "VDEF:"$curif-in_bits_95=$curif-in_bits,90,PERCENT" ";
$graphcmd .= "CDEF:"$curif-out_bits_mul=$curif-out_bits,$multiplier,*" ";
$perc = $multiplier > 0 ? "90" : "10";
$graphcmd .= "VDEF:"$curif-out_bits_95=$curif-out_bits_mul,{$perc},PERCENT" ";

$graphcmd .= "AREA:"$curif-in_bits_block#{$colortrafficdown[1]}:$curif-in-block" ";
$graphcmd .= "AREA:"$curif-in_bits_pass#{$colortrafficdown[0]}:$curif-in-pass:STACK" ";
$graphcmd .= "{$AREA}:"$curif-out_bits_block_neg#{$colortrafficup[1]}:$curif-out-block" ";
$graphcmd .= "{$AREA}:"$curif-out_bits_pass_neg#{$colortrafficup[0]}:$curif-out-pass:STACK" ";
$graphcmd .= "HRULE:"$curif-in_bits_95#{$colortraffic95[1]}:$curif-in (90%)" ";
$graphcmd .= "HRULE:"$curif-out_bits_95#{$colortraffic95[0]}:$curif-out (90%)" ";

$graphcmd .= "COMMENT:"\n" ";
$graphcmd .= "COMMENT:"\t\t  maximum      average      current        period        90th percentile\n" ";

Well what i did was rename the original file on the system to status_rrd_graph_img 95th and then downloaded the file. Made the changes above and uploaded it back calling it what its supposed to be status_rrd_graph_img and then looked at the graphs. I then saved the image of 1 week for the 90th, and then renamed the 95th file back to status_rrd_graph_img and then reloaded the image, and the value changed.

So these are the images attached, just waiting for a developer to confirm what i done is good and it works.
