How to pass the IP to the Input String

marcohuang · Post by **marcohuang** » Fri Nov 16, 2007 8:19 pm

Hi..

I got a problem when I try to pass the IP address from Cacti to the Input String. The Graph shows nothing.Here below is my Input string...

perl <path_cacti>/scripts/meminfo/active.pl <ip>

Here belos is my Perl Script...

use Net::SSH::Perl;
$scon = Net::SSH::Perl->new ($ARGV[0]);
...
...

I assume the IP will be pass to the end of the string...
/scripts/meminfo/active.pl <192.168.22.33>

Can someone who can help me to this quesiton? thank you so much.

Did you read the guide on how to create scripts/templates? http://docs.cacti.net/node/70

In your data input method, specify 'hostname' in the special type code field for IP.

thanks for your information...

Acually I did try perl <path_cacti>/scripts/meminfo/active.pl <hostname>, but seems not work either....Does this issue related to the DNS?

I read from http://docs.cacti.net/node/25 and it shows I can put ip instead of the hostname....

You have to select Special Host Code and specify "hostname" in the input field. It's the last textbox. Then it becomes automatic.

Hi...thanks..

I am new for Cacti. What is the special Host Code? How can I specify "hostname" in the input field?

Simply edit the data input method and look to the last text box. You will see it. Read the text. Also, goto docs.cacti.net for an excellent tutorial or two.

thanks...

Actually i had done with it already..but semes still not work...still no graph shows...where am I missing?

BTW, I can run the script from the terminal "perl inactive.pl 11.22.33.44", I also fixed the IP on the "ARGV[0]" in my script....and it draws the graph..see the pic..

What does the Cacti log reveal? Are you using cmd.php or cactid/spine?

Now, check your poller cache in the same area and see what the script line looks like. Is it what you expected? Post your output from the poller cache.

Thanks for your help.

here below is the info from the poller cache...

Script: perl /var/www/html/cacti/scripts/meminfo/Inactive.pl
RRD: /var/www/html/cacti/rra/ntcsjnt41_inactive_1293.rrd

I expected when cacti run the script, it will add the IP address in the end of the script..like below

perl /var/www/html/cacti/scripts/meminfo/Inactive.pl 11.22.33.44
