Not having fun with custom LLD and zabbix sender

[Datacenter1.com]

Hi

I'm trying to create a custom LLD to discover installed PHP versions, handlers in a cPanel server

I created the following User parameter:

UserParameter=php.discovery,/etc/zabbix/scripts/test.pl

test.pl is very simple:

#!/usr/bin/perl

$first = 1;

print "[\n";

for (`whmapi1 php_get_installed_versions|grep php|tr -d " "|sed 's/-//'|grep -v command:`)
{
($php) = /(\S+)/;

print "\t,\n" if not $first;
$first = 0;

print "\t{\n";
print "\t\t\"{#PHPVERSION}\":\"$php\",\n";
print "\t}\n";
}

print "]\n";

The script output is like:

[
{
"{#PHPVERSION}":"alt-php70",
}
,
{
"{#PHPVERSION}":"alt-php71",
}
,
{
"{#PHPVERSION}":"alt-php72",
}
,
{
"{#PHPVERSION}":"alt-php73",
}
,
{
"{#PHPVERSION}":"alt-php74",
}
]

My discovery rule is like:
Name: php.version
Type: zabbix Agent (active)
Key: php.discovery

The item prototype is like:
Name: {$PHPVERSION}: Handler
Type: Zabbix Trapper
Key: php.handler[{#PHPVERSION}]
Type of information: Character

There is also another script using zabbix sender to send the data pairs:
zsend php.handler[alt-php74] cgi

But i'm getting:
php.handler[alt-php74] cgi
Response from "XXXX:10051": "processed: 0; failed: 1; total: 1; seconds spent: 0.000062"


zabbix server logs shows:
752039:20210201:112735.380 trapper got '{"request":"sender data","data":[{"host":"xxxxxx","key":"php.handler[alt-php74]","value":"cgi"}]}'

So i'm guessing the item prototype is wrong or something else

Any idea or pointers in the right direction will be very much appreciated

Have you completed the LLD process? Created items php.handler[blabla]?
Show a screenshot with the settings of the created element (key).
Which zabbix_sender call string do you use ( without abbreviations)?
After creating items, the information about them should get into the cache - this takes some time.

Its working now, I tweak a little bit the json output and works!

zabbix_get -sxxxxxxx -p 10050 -k php.discovery
{
"data":[
{"{#PHPVERSION}":"alt-php44"}
,{"{#PHPVERSION}":"alt-php51"}
,{"{#PHPVERSION}":"alt-php52"}
,{"{#PHPVERSION}":"alt-php53"}
,{"{#PHPVERSION}":"alt-php54"}
,{"{#PHPVERSION}":"alt-php55"}
,{"{#PHPVERSION}":"alt-php56"}
,{"{#PHPVERSION}":"alt-php70"}
,{"{#PHPVERSION}":"alt-php71"}

]
}
