[SOLVED] Unable to get from script to graph

buznakka · Post by **buznakka** » Wed Oct 15, 2008 2:42 pm

Hello,

I have tried to create a graph from a script in the style of http://docs.cacti.net/?q=node/300

When I check cacti.log, my script gives output for its three output fields in the following format.
output: direct:10 lbhost:61 pool:200

My graph shows values for the "pool" data field, but not for the other two. When I do
rrdtool fetch /path/file.rrd, I see a lot of entries that look like this
1224097200: nan nan nan
1224097500: nan nan nan
1224097800: nan nan nan

mixed in with a few entries that look like this
1224096300: 2.7000000000e+01 nan nan
1224096600: 9.0600000000e+00 nan nan
1224096900: 9.0600000000e+00 nan nan

I'm sure I have done something wrong, but I'm not sure what it is at this point. Can you provide me with some help?

Thanks in advance,
Buz

Please show us a script example from command line. Is the string "output:" prepended to the output itself? Next, I need a screenshot of the data template

Does this do the trick?

My command line
[swalker@cacti:~]$ ./scripts/newstatic.pl http://www.mycompanyname.com/
direct:48 lbhost:6 pool:355[swalker@cacti:~]$

This is all fine. Now, please post the line from "rrdtool update" as given by 2nd link of my sig to see, how the file update is performed

No. That's "rrdtool graph". I need "rrdtool update"

No update seems to be taking place for that file. It's happening for many other files, but not that one.

How about this?

Yea, that would be fine. Does this match your error?

It corresponds to the script that is supposed to be powering the graph.

Your script is spitting out 3 values, but the update only shows one.
Please run a "php -q rebuild_poller_cache.php" to recreate the poller command table and retry

When you edit your Data Template and view each DS tab, is the correct Data Input Output Value drop down value selected for the DS name in question? Seem's odd.

you're right. Something was mixed up in my graph template.

I'm resolved.
