RELEASED: < 1 Minute to 5 Minute Polling Interval Patch

What poller are your using? What is your operating system for the poller? You may have to simply wait for 0.8.6k to obtain this functionality.

Wow- thanks for the quick response - here is what I'm using:

cacti-0.8.6j
solaris 10u3 (aka 5.10)
net-snmp 5.0.9
rrd 1.2.19
php 5.2.3

If you can point me to the areas in the code where this is getting initialized then maybe I can figure something out?

No plugin architecture?

No plugins - was this suppose to be against a specific plugin?

Then, simply apply the files, become familiar with the Documentation provided, and create your data templates.

Sorry, i'm coming into this late and finding the 9-page thread a bit confusing.

I want to be able to do 30 second polling. I'm running 0.8.6g cacti.

What in brief (i can figure out the docs) do I need to download to make this happen?

Thanks!

You need to download 0.8.7 in October when it's released..

Does that have the 30 second polling built-in?

i followed the instructions on page 7 to setup the 10 sec poller and once traffic exceeds 800mb it stops graphing, creating a big gap in my graph. i am using 64-bit graphing.
did i mess up somewhere in the settings that doesn't allow it to graph over 800mb?
i'll also attach a graph of the problem
TIA

edit: i think i found the answer here http://forums.cacti.net/viewtopic.php?t ... ight=800mb
gonna try this then report back

update: i tried the method in the link and it works

I tried to follow the instructions as closely as possible(though a few screenshots were missing)
Everything seemed to go fine, exept I'm never seeing any rrd file created for my 1 min data sources...

Turning on data source shows this:

Code: Select all

C:/www/cactid/rrdtool.exe create \
C:/www/htdocs/cacti/rra/natsuki_traffic_in_29.rrd \
--step 60  \
DS:traffic_out:COUNTER:120:0:100000000 \
DS:traffic_in:COUNTER:120:0:100000000 \
RRA:AVERAGE:0.5:1:500 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:500 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \
RRA:LAST:0.5:1:600 \
RRA:LAST:0.5:6:700 \
RRA:LAST:0.5:24:775 \
RRA:LAST:0.5:288:797 \

However the poller never seems to be doing anything related to that data source... Any hints as of what to do?

Note: if anyone feels like doing/sharing his 1min templates, it would be really nice, importing instead of dup-and-mod is far nicer.

After installing 1 minute polling.
some Graphs drawn have differnet timings. I mean Before installing 1 minute polling patch, all Graphs were drawn at the same time.

This is an important feature. What is happening is it is now taking your 5 minute graphs and spreading them out over the 5 minute interval. Since you now have 5 polling per 5 minutes (1 every minute). This way they are not all polled at once and cause the 1 minute polling to go over the 1 minute interval.

It's not pretty, but it seems to work

Would this work on existing rrd's that have step/heartbeat of 300/600 or would it just break them?

Post by **gandalf** » Mon Oct 29, 2007 2:57 pm

It would not "break" them. But you won't see any details below 5 min unless changing step/heartbeat. It simply updates those rrd's 10 times in 5 minutes.

I installed the latest version the other day via the Debian Ubuntu server. So I am assuming it is the latest version. How dio you know which version you are running?

I tried the patch that was shown previously... but that just stops cacti from working. Obviously I'm running a newer version and things have changed.

I still don't have the option to do do 1min intervals. Can someone help?

cheers
