How to add custom field to Splunk ES Asset dataset

[hpwang1014]

I am new to Splunk and have a question about Asset and Identity data modle.  We are on ES 5.3.0. I am trying to load data into Asset and Identify model, need to add some custom fields in addtion to the default fields.  I tried to add to the main asset fields, also tried to add to the calculated fields.  But when I run |`assets`,  it des not show the custom fields I added.  Any ideas?  Also I did not find in the 5.3.0 document on  how to add the custom fields. Only see it in 6.1.1 ES document.

Support for custom asset fields didn't start until ES 6.0.

Thank you, richgalloway! Looks like we need to upgrade.
