[solved] Selected processes script not working

[exseven]

Hello, hopefully comebody can help with this. I cant get this script to work currently. I am trying to graph my current vsftpd sessions.

the script i am using is http://forums.cacti.net/viewtopic.php?t ... t=proc_cnt

If i run the script from the command line i get the proper number of processes running

Code: Select all

# sh proc_cnt.sh ftpsecure
3

i enabled debugging in the logs and this is what i get for this data source

Code: Select all

# tail -f cacti.log |grep 'proc_cnt\|DS\[25\]'

i dont understand why the output it 'U', not even sure where this is coming from.
any ideas?

[gandalf]

U is set by cacti if the command fails. U stand for Unknown.
Please make sure, that all commands used by the script are given by /full/path/to/command

ok, ive gone through the shell script and changed to absolute paths... still doesn't work. i'm not sure where its going wrong. i have tried to dumb down the script a bit, changed the shell (from bash to sh - works when i run 'sh proc_cnt.sh ftpsecure')

i tried changing the input string under data input methods to start with /bin/sh as well as just sh

also tried full path to the script instead of <path_cacti>, still no further.

Ok fixed, thanks for the help using the NaN walkthough in your signature i ran php -q cmd.php 1 25 and it told me permision denied, changed ownership and still no good.

changed file from 644 to 755 and its working now
