Using nntp
The nntp template is for Usenet News. The check is successful if the
monitor retrieves a newsgroup identification line from the server. An nntp
monitor requires a newsgroup name (for example, "alt.cars.mercedes")
and, if necessary, username and password.
Using sql
The sql template is for service checks on SQL-based services such as
Microsoft SQL Server versions 6.5 and 7.0, and also Sybase. The service
checking is accomplished by performing an SQL login to the service. An
executable program, tdslogin performs the actual login. The check is
successful if the login succeeds.
An sql monitor requires a database (for example, "server_db"),
username, and password.
Using imap
The imap template is for Internet Message Access Protocol. The imap
monitor is essentially a pop3 monitor with the addition of the attribute
folder, which takes the optional key message_num. The check is successful
monitor nntp {
#type nntp
