Getting Data In

WMI route to nullQueue based on host. Is it possible?

When retrieving EventLogs through WMI, the host value is assigned by a system/detault/props.conf config:

[wmi]
TRANSFORMS-FIELDS = wmi-host,...

Can I specify a "local" props where I use the [host::] stanza to apply some further TRANSFORMS?

I am getting troubles as it seems like when my stanza is executed, the events' host field is still the name of the HWF, i.e. my stanza's transforms are executed BEFORE [wmi-host].

My config stanza is like this:

[host::servername]
TRANSFORMS-IAS = sentAllToNullQueue, KeepIAS

p.s. if I modify the stanza to [WMI:WinEventLog:System] my configs work fine, except that they are applied to all the hosts, not just the one I need...

No, it is not possible.

TRANSFORMS are executed AFTER props.conf stanza evaluations. So, if I use transforms to assign a new host or sourcetype, the related [host::....] and [surcetype] stanzas are NOT applied.

The only way to go is to replicate transforms to apply any necessary modifications, such as routing to nullQueue, assign to different index, and so on.
