How to use collectd on a remote host with Universal Forwarder?

Hello,

My goals is to send rrd file data to a splunk indexer.

I have a remote host that currently forwards linux_secure data to the indexer - works fie.

I am NEVER able to create an input for any port tcp or otherwise from this dialog window:

When I configure a TCP forward-server using lthe UF the forward-server never goes active - I only get "cooked" data on the indexer. the host and source type are configured

If I configure a port (tcp or udp) from here: this comes from Data/Data inputs/TCP

This setting comes from Settings/Data/Forwarding and receiving

I get data to the indexer.

I may be missing something.

I installed collectd on a remote host, configured it for the csv plug in, and the cpu plugin - this data is being collected and save to the /var/lib/collectd directory on the remote host.

How can I get this data to splunk and graph it?

I can see data coming in - but cannot do anything with it. The splunk web site says that the HEC inputs must be used to get metrics into splunk. How do I configure the remote host to do this? I.E. send the data from collectd to splunk,

I am open to suggestions and clarification

thanks

Hi @eholz1 ,

There are a few examples you can use to assist getting collectd metrics into Splunk via hec

The Splunk Addon for Linux docs describe how to send collectd via HEC
https://docs.splunk.com/Documentation/AddOns/released/Linux/Configure

The Analytics for Linux app also has working examples.
https://splunkbase.splunk.com/app/3777/#/details

They both use the write_http plugin in collectd.conf

Read the docs page to ensure you are setting the HEC up correctly.

Forgot to ask,

I have collectd installed on the remote host, not the indexer. Should collectd be installed on the indexer and point to the remote host I want to monitor?

Thanks,
