WARNING : result from CMD Not valid

[Stepin]

Hello all,

I spent a lot of time trying to make my script working, debugging it, but it's still generating errors in CACTI.

1) What i would like to do :
execute my SHELL script with a command line argument (beeing a "hostname").

2) What the script does :
Lookups ip address from the hostname specified in the command line argument, and makes an snmpget with a specific OID (querying for the counter of my printers)

3) What my script looks like :

Code: Select all

#! /bin/bash
# Retry the IP address of the hostname
LOOKUP=$(/usr/bin/nmblookup -U 10.33.0.7 -R $1 | awk '{print $1}' | sed -n '2p')

# Check for errors. If "name_query", the host isn't online
if [ $LOOKUP != "name_query" ]; then
	COUNTER=$(/usr/bin/snmpget -v1 -Cf -c public $LOOKUP 1.3.6.1.2.1.43.10.2.1.4.1.1 | awk '{print $4}')
	echo $COUNTER
fi

4) Error
When lunching php poller.php, i get lots of errors, and regarding my script, i can see :
"USAGE : -u serveur -z blalbalbablbl" which is the default page for nmblookup when you don't specify the hostname to lookup (like you're not giving the R value here : nmblookup -U xx.Xxx.xx.xx -R)
Then i got the same default page with SNMPGET, and the error "missing object name". That means it lunchs my script with no ipaddress (LOOKUP variable is empty), and as a result, it supposes the OID is the host, asking then "where is my object name ?".

5) It works in my shell command line but i cannot get it working in Cacti.
I created the data input method, with "host" as the input, and "counter" as the output.
The data source is created.

I don't know what to do. I can't find anywhere what are the commands executed
by poller.php. This way i could tell wether or not cacti is lunching my script and ommiting the <hostname> value !

Can you enlight me please ? Thanks

Please post a screenshot of the definition for the Data Input Method
It seems that you are not passing the host to be queried to the script
R.
