I need to list the number of connections in ESTABLISHED state
attached to a tcp server port. I checked check_tcp but it does not
provide this option.

Is there a standard plugin that provides this function?

thanks,

I do not believe there is a pre-packaged TCP plugin other than the one you used, you can take a look at this list to find the specific one you need:
