External Scripts Unsupported - Timed out.

[troseph]

I have a problem with a couple external scripts I'm trying to use to gather metrics from nginx status page. Script looks like this:

#!/bin/sh
# Set Variables
runfunc=$1
hostIP=$2
port="80"
ftch="curl -s "
#ftch="wget -O- -q "
# Functions to return nginx stats
function active {
        $ftch "http://$hostIP:$port/nginx_status" | grep 'Active' | awk '{print $NF}'
        }

function reading {
        $ftch "http://$hostIP:$port/nginx_status" | grep 'Reading' | awk '{print $2}'
        }

function writing {
        $ftch "http://$hostIP:$port/nginx_status" | grep 'Writing' | awk '{print $4}'
        }

function waiting {
        $ftch "http://$hostIP:$port/nginx_status" | grep 'Waiting' | awk '{print $6}'
        }

function accepts {
        $ftch "http://$hostIP:$port/nginx_status" | awk NR==3 | awk '{print $1}'
        }

function handled {
        $ftch "http://$hostIP:$port/nginx_status" | awk NR==3 | awk '{print $2}'
        }

function requests {
        $ftch "http://$hostIP:$port/nginx_status" | awk NR==3 | awk '{print $3}'
        }
# Run the requested function
$runfunc

Runs fine in shell:

[zabbix@dev scripts]# time ./nginx_status.sh accepts dev02.local
457

real    0m0.018s
user    0m0.000s
sys     0m0.000s

Key (external script):

nginx_status.sh["active","{HOST.HOST1}"]

Yet I still get unsupported "timeout while executing a shell script" from zabbix. I've tried wget, curl, I've rewritten this in PHP, but zabbix will have nothing to do with it.

Any ideas?

What data type is the item configured to receive? Is it set to be an unsigned integer? If so, is your item putting a newline character at the end of the line? That would cause it to not be supported (because a newline is definitely not a digit ).

If what I mentioned above doesn't resolve the problem, try setting the data type to text to see if you can get data into the item at all (regardless of what Zabbix thinks it is). If that works, then you'll need to identify why Zabbix thinks that it isn't an unsigned integer (assuming that's what it should be).

I'll try that, but it seems it's not even running the script. You're thinking zabbix would throw "timeout while executing a shell script" if the data type was wrong or it's not getting anything?

[troseph]

still no love with it set as a text item not returning anything, going unsupported as soon as it runs.

What is zabbix_agent DEBUG=4 shows? Do you try zabbix_get?
