gmirror provider's status monitoring in FreeBSD

[ARA]

Here is my proposition of monitoring gmirror provider's status in FreeBSD:

On monitored host:
------------------

echo 'UserParameter=gmirror_status[*],gmirror status|sed -rn "s;(mirror/$1)  (.+) (.+);\2;p"' >> /usr/local/etc/zabbix/zabbix_agentd.conf

/usr/local/etc/rc.d/zabbix_agentd restart

On server:
----------
Add item:

Description: gmirror provider $1 status
Key: gmirror_status[gm0]
Type of information: Character

Add trigger for created item:

Name: gmirror provider gm0 status on {HOSTNAME}
Expression: {Template_Foo:gmirror_status[gm0].str("COMPLETE")}#1

[dmitryt]

in FreeBSD 8.0-RELEASE

$ gmirror status|sed -rn "s;(mirror/$1)  (.+) (.+);\2;p"
sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

I use

gmirror_status[*],gmirror status|grep $1|awk '{print $ 2}'
