Configuring an address to monitor

Scheduler : Pinging an address

This is the frist step in a series of Wizard generation steps to set up a new monitor on an Internet address. To configure a monitored address you must enter a name for it (this is used in alert messages and should describe the page) and its internet address (e.g. www.silurian.com) or IP address (e.g. 212.168.203.56). The WhoIs button gives details about the owner of the IP address using a WhoIs lookup command.

There are two types of accessibility checks provided.

The first option Ping sends an ICMP echo (Ping message) and times the delay before an echo response comes back. Some servers do not respond to Ping requests because hackers have used this as an attempted 'denial of service' attack.

Alternatively you can use the Connect option to measure the time taken to set up a connection on a particular port number. No data is sent, as soon as the connection is set up it is brought down again. Once again some sites will not permit this type of connection. Port number 80 is the standard HTTP port.

You need to be running Site Vigil with sufficient privileges to use sockets, under NT/WIn2K or XP this means having administrator privileges.

The maximum access time field allows you to be made aware if an address is taking too long to communicate with. Although SiteVigil can not easily determine why it might take so long (it may be Internet congestion) you will be made aware of possible problems.
