discovery based on zabbix trapper

[umask]

Hi!

I need to collect iostat information on few FreeBSD hosts.
Because iostat is long running process I run it and collect information about all disks during 60-120 seconds.

Collected information (after formatting) passed to zabbix-server using zabbix_sender.

Because I have few servers with different disks count I have to manually create mass of items per server. And now I'm trying use low level discovery...

My question is:

How I need pass to zabbix-server keys ({#DISKNAME}) which described in Discovery Rule with type Zabbix trapper?

[umask]

If I send data like this:

# zabbix_sender -c /usr/local/etc/zabbix2/zabbix_agentd.conf -k system.iostat.discovery -v -s `hostname` -o '
{
"data":[
{"{#DISKNAME}":"mfid0"},
{"{#DISKNAME}":"mfid1"},
{"{#DISKNAME}":"md0"},
{"{#DISKNAME}":"cd0"},
{"{#DISKNAME}":"pass0"}]}
'

Zabbix-server writes in log:

My investigraion shows that global regexp does not work properly.

In web interface it works!



But autodiscovery works only if Regexp field empty in Discovery Rule.

Dear Zabbix Team,

could you confirm that bug exists in regexp filtering on items from zabbix trapper?

I still cant use regexps for filter disk names. Discovery works fine, but I no need items for virtual or inmemory disks and need to exclude them.

If somebody need - there are sample resulsts from one of my server:




I will post template if all will works fine with no known issues (like broken regexps).
