How to telnet or ping on a specific port at certain intervals in Splunk to check if the port is listening on a host?

Hi Team

I am getting a list of hosts and their corresponding ports in the indexed data and I want to keep checking whether the port is listening on that host using Splunk every say 3 min. How can I do this?

e.g. Data I am getting from indexing
HOST=abc.pqr.com,PORT=9001
HOST=11.11.11.11,PORT=9242

In Linux, I can check if a port is listening using standard telnet command. How can I do the same in Splunk?
I found the telnetstatus app, but the same is not considering a specific port. Any simple and direct app suggestions appreciated.

You need to write your own scripted input (which I am sure is all that the telnetstatus app is):
