perl script not running

fsckedagain · Post by **fsckedagain** » Fri Sep 26, 2008 11:08 am

I am really trying to get this working, so bear with me please.

When the poller runs, it isn't running one of the scripts so I get NaN's pon the graph. How do I begin to troubleshoot the script not running?

I see the other scripts (default localhost scripts) in the log but not the netapp one.

TIA I will continue googling and foruming to look for the answer.

FYI, Gandalf, you sig is gone.

Can you run your script by manually?
There is some good information here.

Well, it's the NetApp template using the OnTap SDK and I am new to this cacti stuff. I think you pointed me in the right direction, but I am not sure what to put for data input and data output values.

I am going to try and figure it out.

I looked at that perl script before, but never used it.
I do remember there being a usage summary in the script, which would help show you which parameters to pass it.

Also, check that your Perl environment has all the necessary dependencies installed to run the script.

Yep, I can run it manually. The poller just never tries to run it at all. I cranked logging up to debug for a couple cycles and it never attempts it.

You need to provide both Technical Support and Poller Log. Also, does this item appear in the Poller Cache?

No, the snmp queries for the same host appear in the poller cache, but not the perl script.

This is the DataONTAP SDK script from script/templates section.

the tech supp and log are in the zip file.

thanks!

What happens if you re-populate the poller cache? Until you find it in the Poller Cache, the graph will never work.

I just noticed this, too.

notice it says 2 hosts, but isn't running the perl script for the other host. It is called netapp-something-or-other.pl

I am not interested in the poller output, I need to your review the poller cache. Two different things entirely. Do you know how to "Repopulate the Poller Cache"?

Yes. Learn PHP and launch this script.

Nope, rebuilding didn't do it. I just clicked the rebuild link under system utilities, should that work ok?

Also at the top after clicking, I got this error:

Warning: Division by zero in /var/www/cacti-0.8.7b/lib/api_poller.php on line 119

ok. So during some troubleshooting yesterday I changed poller interval to 1 minute so I would get faster polls (I thought) when I changed it back to 5 minutes before I left it horked it up. That is where that error comes from. If I change poller interval back to 1 minute the error goes away.

Sorry for the triple post. I now have the scripts running, it was due to stupid human tricks by me.

Now I just need to figure out how to make the graphs slope instead of step and figure out why I can't set the poller back to 5 minutes. I will research those and start new threads if needed. Sorry for wasting your time, Witness.

Thanks so much.

I haven't got your "slope instead of step". You want to rewrite rrdtool renderer?
