Zabbix 3.4.7 Agent Auto-registration | multiple HostMetadataItems

[pimp_vader]

Apologies if this has been answered somewhere already but I spent the last 2.5 hours combing the forums and found nothing.

I am able to get auto-registration, assign a template, and get the host assigned to a host group using configuration items within the /etc/zabbix/zabbix_agentd.conf file, my question is can I string together multiple HostMetadataItems to leverage multiple actions
e.g.

metadata like Linux add to Linux servers
metadata like linux link linuxserver template
metadata like ovirt add to Vitual Machines group


I am finding the first 2 will process fine, the third doesn't appear to be triggered.
My aget.conf is set like this

### Option: HostMetadataItem
#       Optional parameter that defines an item used for getting host metadata.
#       Host metadata is used at host auto-registration process.
#       During an auto-registration request an agent will log a warning message if
#       the value returned by specified item is over limit of 255 characters.
#       This option is only used when HostMetadata is not defined.
#
# Mandatory: no
# Default:
# HostMetadataItem=

HostMetadataItem=system.uname
HostMetadataItem=system.run['facter virtual']

FWIW this is what I am getting returned when I do a zabbix_get

-bash-4.2$ zabbix_get -s <IPADDR> -p 10050 -k system.run['facter virtual']
ovirt

And I do see the system.run['facter virtual'] being called and successfully executed in the agent logs on the target host


I am starting to think that after it processes the first HostMetadataItem it stops if this is the case is there a method that will allow for multiple HostMetadataItems to be leveraged for registration purposes?

Thanks in advance

I think that HostMetadataItem could not describe multiple lines.
Try to arrange the necessary character strings in the definition of one line.

[pimp_vader]

Is there a certain style in which they should be strung together?
e.g.

HostMetadataItem=system.uname | HostMetadatItem=system.run['facter virtual']
HostMetadataItem=system.uname | system.run['facter virtual']
HostMetadataItem=system.uname ; HostMetadatItem=system.run['facter virtual']
HostMetadataItem=system.uname , HostMetadatItem=system.run['facter virtual']

Each variation that I have tried so far returns some variation of

 2807:20180322:140323.780 cannot get host metadata using "system.uname | HostMetadatItem=system.run['facter virtual']" item specified by "HostMetadataItem" configuration parameter

And thank you for the response

bump since I have not found a workable solution yet

[dxmski]

did you ever find the solution to this? i'm looking at setting up something similar where I have different hosts within different subnets, different domains and different operating systems. Is it best to just have one metadataitem that calls a userparameter that grabs all that information into one string?

My solution:

/etc/zabbix/zabbix_agentd.conf:
HostMetadataItem="vfs.file.contents['/etc/zabbix/metadata']"

`cat /etc/zabbix/metadata`:
linux=os
smartmontools=present
docker=present
