Monitoring Internet Services

Traverse has built-in monitors for all internet services such as:

• POP3 - simulate a user and log in to the POP server
• IMAP - simulate a user and log in to the IMAP mail server
• SMTP - connect and issue the SMTP handshake
• FTP - simulate a user and log in to the FTP server
• HTTP/HTTPS - download a page and check if it can be downloaded completely. Also see the URL Transaction Monitor below.
• DNS - query and match the response from the DNS servers
• Radius - make a query to the radius server
• DHCP - request an address from the DHCP server

These require parameters custom to each service in order to do a complete synthetic transaction and test the service. The provisioning of these tests is described in Managing Standard Tests.

Traverse measures the time to complete each transaction, and raises an alert if the response time exceeds the warning or critical thresholds. It also generates an alert if the transaction is incomplete or cannot be completed or times out.
