Discovery ExternalScript

[Spikedammage]

Hi everybody,

Im using zabbix 2.0.3 on a debian machine.

I want to monitor interrupts/s per device on several debian server. I searched some mibs which inlcude SNMP OIDs for those values but i found nothing... So i decided to make a script (IRQDiscoveryCheck.sh) which ll connect to distant servers by ssh protocol and execute the commande : cat /proc/interrupts. Then the same script ll store in an array the ID and the name of each IRQ. Finaly the script convert the array in json format to be understable by zabbix.

The output of IRQDiscoveryCheck.sh :

{
"data": [
{
"{#IRQNum}": "0",
"{#IRQName}": "timer"
},
{
"{#IRQNum}": "1",
"{#IRQName}": "i8042"
},
{
"{#IRQNum}": "6",
"{#IRQName}": "floppy"
},
.....
{
"{#IRQNum}": "29",
"{#IRQName}": "eth1"
}
]
}

In zabbix frontend i created a Discovery rule like this :

Then added a prototype item which call an other external script (IRQPerSec.sh) with a parameter : the IRQNum which is given by the IRQDiscoveryCheck.sh

My problem is : When zabbix try to create new items, the frontend says :

"Cannot create item [IRQPerSec.sh[{#IRQNum}]]: item already exists
Cannot create item [IRQPerSec.sh[{#IRQNum}]]: item already exi"

I think the problem is that the item prototype cannot resolve the name of the macro {#IRQNum}. I think i did something wrong in frontend configuration but cant find what..

If anyone can help me with that, could be really nice !!

Thanks

Shouldn't macros be UPPERCASE ?

Edit:
Yup, documentation says:

The following characters are allowed in the macro names: A-Z , 0-9 , _ , .

You right, i just retried with UPPERCASE macro and it works perfectly!

Thanks a lot for your reply!
