Sensors
Since each network device (or "server") usually has several
parameters or services that should be monitored you can set up various sensors
to monitor each and every aspect of a server (e.g. CPU load, webserver
responsiveness, SMTP responsiveness, PING time, etc.) So a "server" has several
"sensors" by which you will monitor all aspects of the server.
You can choose from several different types of sensors that
include
· PING
· PORT
· HTTP
· HTTP
Advanced/Transaction
· DNS
· SMTP
· POP3
· FTP
For more information about sensor types see Sensor Types in Detail. For more information about
editing sensors see the Managing Sensors section of
the manual.
