I followed the PDF instructions but somehow when doing step 5 - "Adjust Data Query" after updating the "SNMP - Interface Statistics" with the 1 min poll cacti managed to kill all the "Suggested values" on the page. I did this multiple times and each time cacti managed to kill all the suggested values. Now when I create new graphs they have default values - no good. Either something is 1) broken with cacti 0.8.6.i, 2) I missed something that broke the Data Query or 3) I donDevil wrote:Ive found an error in The PDF file attached to this thread.
In section 2.1 "Click Devices..." under section 2 "Create new RRA" should say "Click 'Data Sources' ...
Otherwise a perfect/easy to follow guide...
regards Devil.

hi, what if i set the interval to 2 min, will the 1 min graph still look the same as when i set the interval to 1 min? thanks.
EDIT: what's the difference if i set the interval to 1 min but the scheduled task is set to run every 5 min?
what does interval do compared to scheduled task run time? thanks

If you are polling every minute, the scheduled task must fire every minute. If you are polling every two minutes, the scheduled task must poll every two minutes. However, you should not poll any less frequently than 5 minutes, even though some data sources may only be polled ever few hours.

thanks for the reply. i also noticed that the daily 5 min average of the bits/sec 1 min traffic is more should i say detailed than the daily 5 min average of the bits/sec traffic. is that normal?

Of course, the more frequently you measure, the more accurate the graphs "appear".

Oh, so what you are saying is that you still maintained the 5 minute average and the poller interval was 1 minute. Well here's the deal, each 5 minute poll is distributed so, as you know, traffic is bursty, and in any 1 minute period, you can go from 0 to saturation. So, numbers will fluctuate.

What Does This Patch Do?
Can someone explain what this patch actually does?
I've been running Cacti with 1-minute polling (just fine) for quite awhile now just by altering the Steps, Rows, and Heartbeat fields -- and the cron job. Why do I need this patch? What does it change? Why wasn't it incorporated in the last release?
Also, why not have a version of cactid that actually runs as a daemon? Why not add some smarts to Cacti and cactid so all we say is what kind of polling resolution we want for a data source per period, and then Cacti and cactid automatically handle scheduling and figure out the steps, rows, timespan, heartbeat, whatever -- stuff???

The big difference here is that if you define DS's that are to be polled every 10 minutes, hour, 4 hours, they will be polled only that often. If you want 5 minute granularity and have a 1 minute poll interval, those items get polled every minute. This limits scalability. Therefore, I have introduced this patch.
Do you understand now?

Using cacti 0.8.6h
Hi All,
Thanks to everyones work and input on making the polling interval flexible from 5 minutes to lesser.
But I am facing some problems with the scripts and I am wondering if anyone can please help me out with this.
I am using the cacti version 0.8.6h and the scripts are not working. Can anyone please help me resolve this issue as I need to get the polling interval to 1 minute.
I will appreciate any help, suggestions or inputs I receive.
Thank you
