Available Sensor Types

Since each network device (or "server") usually has several parameters or services that must be monitored, you can set up various sensors to monitor each and every aspect of a server (e.g. web server responsiveness, SMTP responsiveness, PING times, etc.). In bello’s nomenclature a "server" has several "sensors" by which it will monitor all aspects of the server.

Available sensor types include:

·      PING--Sends standard PING to the server/device.

·      PORT--Opens a specified TCP/IP port on aserver to check if the attached service accepts connection attempts (this type usually can be used to monitor service types that bello does not support natively).

·      HTTP--Simple HTTP/HTTPS request retrieving a webpage.

·      HTTP Advanced--Advanced HTTP Sensor for more complex webpage monitoring, adds html content check, proxy, and authentication settings to the standard HTTP sensor).

·      HTTP Transaction--Checks several web pages in sequence (e.g. taking a shopping cart to the checkout of an ecommerce website).

·      DNS--Checks DNS server (Domain Name Server).

·      SMTP--Checks SMTP server (Simple Mail Transfer Protocol, the Internet’s standard for email).

·      POP3--Checks POP3 server (Post Office Protocol).

·      FTP--Checks FTP server (File Transfer Protocol).
