how does UF handle both metrics and event data

[junyuw]

I have my UF and indexer set up and what I want to do is sending both metrics and event data from UF to indexer.
from my understanding what I could do is set up two stanzas in inputs.conf of indexer like below

[tcp://9997]
connection_host = dns
index = event_index
sourcetype = syslog

[tcp://9998]
connection_host = dns
index = metric_index
sourcetype = syslog

and the idea situation would be sending metric data to <indexer_ip>:9998 and event data to <indexer_ip>:9997 separately
but the problem is it seems impossible to achieve this through configuring outputs.conf (I could send both data to both ports using the data cloning technique mentioned in doc, but that's not ideal)

So is there a way to achieve this separation of data forwarding?

Do not use tcp for sending data UF->IDX, use splunktcp / splunktcp-ssl. One connection of that can send data to any number of indexes as defined in the UF's inputs.conf.
