Value should be a JSON object.

[xrouted]

Hello,

my server is zabbix 3.0.4 installed on Debian 8. When i try to using the LLD external script as described here: https://share.zabbix.com/operating-s...-automatically ....

I can't understand, why this makes a mistake, although I use Bash external script. The error is: Value should be a JSON object. ???

Where I'm wrong?

And this is external script:

#!/bin/bash
usage(){ echo "Usage: ./$(basename $0) hostname. For example:
./$(basename $0) server1.example.com";} if [ -z $1 ]; then usage; exit
1; fi IFS=$'\n' LIST=$(nmap -T5 -F ${1} | grep 'open') echo -n
'{"data":[' for s in $LIST; do
        PORT=$(echo $s | cut -d/ -f1)
        PROTO=$(echo $s | cut -d/ -f2 | awk '{sub(/[[:space:]].*/,"");
print}')
        SERVICE=$(echo $s | awk '{print $3}')
        echo -n
'{"{#PORT}":"'${PORT}'","{#PROTO}":"'${PROTO}'","{#SERVICE}":"'${SERVICE}'"},'
done |sed -e 's:\},$:\}:' echo -n ']}'
unset IFS

Hi,

Having the exact same problem with the same script provided in Zabbix Share (https://share.zabbix.com/operating-s...-automatically).

I checked that script run successful under zabbix user :

# su - zabbix -c "/usr/lib/zabbix/externalscripts/tcp-discovery.sh XX.YY.ZZZ.231" -s /bin/bash
{"data":[{"{#PORT}":"21","{#PROTO}":"tcp","{#SERVICE}":"ftp"},{"{#PORT}":"80","{#PROTO}":"tcp","{#SERVICE}":"http"},{"{#PORT}":"443","{#PROTO}":"tcp","{#SERVICE}":"https"}]}

Does someone have an idea ?

Thank you

Ok I found the problem.
I had a blank first line in my script. It was added by Ansible and {% raw %} usage.
