Sorry, typo. Corrected it.

Ok (:

So what steps should I do to achieve my second goal that is Monthly 95th percentile 5 minutes average ?

I am really lost here..

Thanks !

Hmm, AFAIK that should be done on the monthly graph. That is: select the timespan to be monthly and that do. Else, please post a screenshot and describe in more detail

I was reading closely http://forums.cacti.net/about16254.html and I think it was discussed the same thing, but I really don't understand what exactly I should be changing my rra values to.

If you could lighten this up for me and possible others who are still in doubt iit would be great.

Also one other question :

 <row><v> 3.8059103704e+08 </v><v> 4.7942495966e+07 </v></row>

These two values would be IN/OUT ?

Thanks Alot!

IMHO, you won't have to change anything if you only want to see monthly averages. An average will not change, whether being computed for lots of 5 min intervals or for already averaged 30 min intervals. Bot, average(5min) and average(average(5min)) should yield the same value. You may perform an example with only some 60 values or the like and compute both kinds of averages to verify my statement.

I would appreciate creating a new topic, because this is different stuff. But yes, one is IN and one is OUT, if this is from a traffic rrd. Which is what depends on the header XML line. But remember, this is COUNTER stuff (rrdtool always stores rates, no absolute values)

Hello ,

What about Vlan speed, if we have one Te interface in mode access with Vlxx and we also want to graph traffic thru that Vlan correctly what is to be done ?
I have tried tuning the Vlan rrd file to maxspeed 10G but I cant get it to graph more than 3G, when the Te interface upper limit is beyond the 5.5G limit.

Thank You !

What if we have one Te interface in mode access with some Vlan int and we actually want to graph the Vlan traffic as well .

What is to be done in order to get correct readings on the Vlan interface, because I cant read more than 3Gbits on the vlan interface where on the Te interface after tuning it I get more than 5Gbits.

Anyone hit this wall ?

Thank You !

Hi,

Sorry to dig up this old thread.

I'm running cacti-0.8.6h and am trying to get ten gig interfaces on some Cisco 6500's working in Cacti, but i'm not seeing the correct throughput being graphed.

Are there bugs with ten Gig interfaces and version h? I've tried editing the data source max value to = 1000000000 instead of the default, but no real change. Do I need version i or j to get this to work correctly?

Hello Ben ,

You have to fine tune both input and output with rrdtool tune ..

Are you sure you are doing more than what you see on the cacti graph ?

Hi,

Yeah the Te interfaces on the router are pushing much more data through than is getting displayed by cacti (i'm currently generating traffic to try work out what's wrong)

I guess i'll re-read this thread, though it doesnt sound like an easy fix. Is editing the data source Maximum Value to = 1000000000 the same as running rddtool?

Have you got it working reliably? We're about to go live with a large IP storage network and I need something that's going to be able to graph the throughput that's easy to setup.

Ok, I may have gotten somewhere, as you can see in the attached i'm getting more solid data out of it now.

Only problem is it's over a 5 min average, so it's leveling off a lot of traffic spikes/bursts. Just need to work out a way to get the average down to a minute or something similar. I've edited the 'step' field for the data template from 300 to 60, so we'll see what that does.

Arg, now i've edited the data source stepping and it's stopped graphing ANY data.

Grr, changed it all back to what it was and still not getting any data anymore, debug all comes back ok. I can't win!

Post by **gandalf** » Wed May 16, 2007 2:44 pm

Please post output of rrdtool info for that rrd file.
Changing stepping only was not that good of an idea ... It's related to some other items like minimal_heartbeat and the polling interval. You may find some hints at Announcements when you search for the 1 min polling patch

Ok,

I deleted my old graphs and had to re-create them, then they started displaying 64bit data again.

I'll have a look into the 1 min patch then, cheers.
