External check "is not supported by agent" ??

[Martin Strand]

Hi all.
I'm trying to get an external check working with Zabbix 1.4.4 but the server log keeps saying:

Parameter [check.ntp] is not supported by agent on host

which is rather surprising, since the agent isn't supposed to be involved at all. I checked the external script but its atime hasn't changed so it appears the server doesn't even understand that this is supposed to be an external check. Everything is configured correctly as far as I can see, is this a known bug in 1.4.4 or have I completely misunderstood how external checks work?

09:~# grep External /etc/zabbix/zabbix_server.conf
ExternalScripts=/etc/zabbix/externalscripts/
09:~# ll --time=atime /etc/zabbix/externalscripts/
total 8
-rwxr-xr-x 1 root root  66 Mar 18 02:16 check.ntp

Thanks,
Martin

I've never used External checks but as I was reading the manual I've found :

Syntax of item’s key:
script[parameters]
script – name of the script.
parameters – list of command line parameters.

Have you tried to write the key value like that :

check.ntp[]

Yep, I added the brackets and now it works great. Thanks!
