Item LLD / Auto-Discovery with Zabbix Trapper

[mitchie_moe]

hi everyone,

i'm using zabbix for monitoring a SIP-network.
inputfiles (XML) are generated by the network elements every 5 minutes.
they get parsed/preprocessed with a perl-script in order to generate an outputfile that /usr/bin/zabbix_sender can read.
hosts and items are manually preconfigured.

as an example, this is the way that the outputfile looks like:

HostABC SipRejectCause400 1594911600 0
HostABC SipRejectCause403 1594911600 14
HostABC SipRejectCause404 1594911600 55
HostABC SipRejectCause421 1594911600 0
HostABC SipRejectCause500 1594911600 9
HostABC SipRejectCause503 1594911600 19

all those items are preconfiured, as mentioned before.
i would like to add a "Discovery Rule" to my template to automatically add another item if the XML contains an item that is not preconfigured, like this:

HostABC SipRejectCause499 1594911600 86

the name and the key of the new item shall be "SipRejectCause499".
what do i have to put into the name- and key- field of the discovery-rule? $_ ? $1 ?
is it possible at all?

thanks, michael

this is my setup at the moment:






zabbix_sender -z localhost -s "zabbix_script" -k newkey -o '{"data":[{"{#KEYNAME}":"SipRejectCause499"}]}'
Response from "localhost:10051": "processed: 1; failed: 0; total: 1; seconds spent: 0.000236"

will result in:



so the name is perfect, but i would like to get rid of: " key[ ] " to archive something like this:




is there any chance i can solve this with the discovery-function?

What happens if you change your Item Prototype so that instead of Key: key[{#KEYNAME}] you instead try Key: {#KEYNAME}

?

Does that accomplish what you want?

hi tim,
thanks for your suggestion. unfortunatly it's not working, incorrect syntax:


i have tried
{#KEYNAME}
[{#KEYNAME}]
[#KEYNAME]

all with the same result.

To get what you want (as in pictures) in field “key“ in item prototype just use lld macro {#KEYNAME}.

thanks hamardaban, but this "value" is not accepted, as you can see in post #4. or did you mean something different?
this is the config which will lead to the error in post #4:



btw, i am using Zabbix 4.4.5. on a RedHat OS

I saw that you tried to use the proposed syntax and wrote that it is correct, and not some other.
Try do not use $1 as the name of the data item prototype. Specify the macro and some text explicitly.
