How to create a list of all indexes with source, host, and sourcetype with last seen field?

Hello all, I'm currently working on figuring how to create a list of as mentioned in the title with the last seen field.
This field will show when the host was last seen in our logs.

It's kind of similar to the solution below but will only list last seen time for all hosts.

Thank you in advance for your assistance.
