Can someone tell me how to configure MRTG to do 95th percentile?

*MRTG* can't do 95th percentile. There are, however, a number of external packages which can compute it for you.

95.pl and the patch would do the job. :cool:

Note, however, that the code linked above does not work with rrdtool, making it rather deprecated.

Yeah, does anyone know where I can get a version of this that will work with the latest version of MRTG? Or perhaps the version of MRTG this was written for? I thought that it was going to work anyway, but it doesn't appear to be.

As far as I know, 95.pl works fine with the latest version of MRTG, as long as rrdtool isn't being used. With rrdtool you need a new way of extracting values from the data file.

MRTG, 95.pl, and cisco 2924.

When you install MRTG & 95.pl, does it comment out your port 1 (eth0/0)? Somehow my port 1 (ethernet 0/0) is commented out, and I am trying to figure what have caused it.

:cool:

The patch no longer works... All I get in the HTML files is:

"Last 30 days usage (Metered 95%): kb/sec"

It doesn't actually imput the value from what 95.pl is pulling.

Any ideas?

Did you wait for 95.pl to run and create the file on disk which stores the value? The patched mrtg doesn't actually do any 95th percentile work, it just reads a file created by 95.pl.

jkehe,

You need to modify the version in the patch to the current version of your MRTG.

I think you have to wait 24 hours for the 95th percentile to show up. :cool:

DUH! Yeah, oops. It's way too late to be playing with this stuff, what the hell was I thinking. Hehehe. Thanks!

Do you know of a script that would work with MRTG to produce graph on each account via dedicated/static IP? :cool:

I know of people graphing eth0, but I've never heard of each individual IP address. I'm sure it's possible, however.

jahsh,

I don't know why my port 1 (eth0) got commented out.
Do you know?

keep in mind I dont know to much about this either but the only difference I see is that I started my 1st Target (port-1) at
2:<com string>@x.x.x.x and you started at 1, you might try adjusting yours to start at 2 and then go from there. I have a question for you. How did you get the 95th percentile to graph on the html output?

You use the patch and 95.pl at http://www.seanadams.com/95/.

Let me create an mrtg.cfg file using your code to see if it helps. :D

Fremont Servers

12-18-2001, 04:11 PM

I use cfgmaker to create mrtg.cfg

Whenever I add a server to a port, I need to run cfgmaker for it to recognize/update the ports.

If I create my own mrtg.cfg,how do you get it to recognize/update the ports?

:cool:
