Data Source Debug

[dpoulsen]

Hi,

I wrote a script to grab traffic statistics off of some of our wireless gear and followed the guide here: http://forums.cacti.net/about11288.html

I'm having a problem where only the first item the script returns is getting graphed and I am not quite sure why.

Data Source Debug reveals this:
Data Source Debug

/usr/bin/rrdtool create \
/var/www/cacti-0.8.6h/rra/jcmc_to_8_erie_trango_5830.rrd \

What does the 'U' signify versus the '100'? If I run the script from the command line it returns:

EthIn:2008036958 EthOut:473822604 RfIn:476149140 RfOut:1975176576

Poller.php with DEBUG enabled yields:

Does any of this mean anything that could point to a solution? What other information could be useful for me to post here?

Thank you for your help.

Please send a screenshot of your Data Input Method. Basically, you'll have to define each Output field seperately (just like the rtt in the example you referenced); e.g. ethIn, ethOut, rfOut, rfIn

/usr/bin/rrdtool create \
/var/www/cacti-0.8.6h/rra/jcmc_to_8_erie_trango_5830.rrd \
--step 300 \
DS:trango_5830_ethIn:COUNTER:600:0:U \
DS:trango_5830_ethOut:COUNTER:600:0:100 \
DS:trango_5830_rfOut:COUNTER:600:0:100 \
DS:trango_5830_rfIn:COUNTER:600:0:100 \
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:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

What does the 'U' signify versus the '100'?

Two hints: U denotes Unknown or no maximum boundary defined. This is the default for the [first] ds only. 100 is the default for subsequents ds'. And I bet that's not the maximum value you want to configure for each of them. As my example holds for one output field only, this was not mentioned.

EthIn:2008036958 EthOut:473822604 RfIn:476149140 RfOut:1975176576

Poller.php with DEBUG enabled yields:

Ah, I see that you already have defined all Output Fields. But the readings seem to exceed the maximum value boundary mentioned above, do they?

Ahhhhh! The problem was in fact the maximum value boundry. Thank you!
