ksh cacti script works, no graph

[scottbowden23]

The script is working per the logs, just a ps -ef|wc $1 for figuring out how to do this.

log output:
06/02/2006 10:15:11 PM - CMDPHP: Poller[0] Host[64] DS[2034]CMD: /tmp/cacti.ksh -l, output: 72

But the graph doesn't display
ERROR: Could not parse line 'GPRINT::LAST:Current\:%8.2lf%s'

Data Source:
/usr/local/bin/rrdtool create \
/usr/local/apache2/htdocs/cacti/rra/localhost_wc_2034.rrd \

RRA:LAST:0.5:24:775 \

Also running strings on the rdd file show data is being put in the file. I am using the type GUAGE set at the Data Source level.

strings output:

Please provide a little direction on how to have my output: value of 72 graph correctly.

Thank you,

PS, searching the board and found a little more info, but I still have the problem.

Please select your graph from Graph Management and switch to DEBUG mode, then. Post the whole rrdtool graph command. There's definitively sth wrong with the template. Suppose, the reference to the data source is missing

I have attached what I think you mean. I turned on Debug for the graph I'm having trouble with. However, I only see the error not the whole rrdtool command? Where can I grab that whole command from?

[gandalf]

Oops, sorry. This feature was introduced lately.
So please select the graph from the Graphs Tab to see all 4 rra's. Then click on one of the wrenches
Reinhard

[scottbowden23]

I found the output but forgive me, my ability to read rrd tool is very limited at best.

Below this point is one that works, I seem to be missing a DEF in the broken graph?

the DEF statements are missing here!

Your suggestion is quite right. So the Graph Template is broken. Select the item you suppose to be graphed (as a LINE or AREA) and choose the correct data source AND a color for it. If in doubt, post a screenshot of the graph item/graph template

lvm, has anyone told you lately that you rock, because you do! That did it, now I know how to incorporate my nagios monitoring into my trending with cacti.

Thank you for your help,

Scott Bowden

... now I know how to incorporate my nagios monitoring into my trending with cacti.

Would you mind sharing your results with the community? There is already a steadily growing "fan club" of cacti AND nagios users as can be seen at Add-Ons and Scripts and Templates
