N-central Help

NNTP service

The NNTP service checks the status of the NNTP process on the network device. NNTP is a request-reply protocol that is similar in style to the SMTP or FTP. It provides a network news transport service and is the standard for the Internet exchange of Usenet messages. 

SolarWinds N-central can determine the up or down status of the NNTP service. The NNTP service does not use the Warning state.

SolarWinds N-central averages the availability of the NNTP service over the scan interval. It compares the availability of the NNTP service to the threshold to determine the status.
