Zabbix 1.8.1 custom parameter, not liking "-" symbol

[Twirrim]

I've got a custom script on the box that will pull out some specific metrics I'm interested in when provided with the process name.

For testing I've got the entry in zabbix_agent.conf:

UserParameter=dirty[*],/usr/local/bin/dirty $1

running it with part of the process name:

/usr/local/sbin/zabbix_agent -t dirty[8115]
dirty[/usr/local/bin/dirty 8115]     [t|579.578]

if I try and run it with a little bit more:

/usr/local/sbin/zabbix_agent -t dirty[8115-alf]
dirty[/usr/local/bin/dirty /usr/local/bin/dirty $1]  [m|ZBX_NOTSUPPORTED]

as soon as I add in that "-" it switches to NOTSUPPORTED, and if you look at the command line it says it's running its decided to repeat the name of the script, and not substitute in the $1 I passed it..

Running the script manually works fine:

/usr/local/bin/dirty 8115-alf
579.32

Is this a bug in the agent or am I missing something obvious?

Some characters are not supported as parameters.
If you want to still use it or need it you need to set an
option in zabbix_agentd to support this special chars.
I have not in mind the parameter, but have is used it somewhere already, as I had similiar probs.
