Specifying The Test's Timeout; Specifying The Probe's Tolerance - HP 7102dl - ProCurve Secure Router Configuration Manual

For example, a network administrator could enter this command to probe the
company's FTP server:
ProCurve(config-probe-FTPServer)# destination www.company_a.com port 21
For HTTP request probes, the default destination port is 80. If your server uses
a different port, you can specify that. For example, if you want to specify port
8080, enter:
ProCurve(config-probe-WebServer)# destination www.company_a.com port 8080

Specifying the Test's Timeout

The timeout value determines the length of time within which a probe packet
must return. For ICMP echo and TCP connect probes, the timeout solely
determines whether a test passes: the response must return within the allotted
time, or the test fails. For HTTP request packets, other conditions can affect
the success of the test. (See "Requiring a Particular Status in the Web Server's
Response" on page 9-21 and "Requiring Particular Information from the Web
Server" on page 9-23.)
To specify the timeout, from the network monitor probe configuration mode
context, enter:
Syntax: timeout <milliseconds>
The valid range is from 250 to 4,294,967,295 milliseconds. The default value
depends on the probe type:
ICMP echo: 1,500 milliseconds (1.5 seconds)
TCP connect: 10,000 milliseconds (10 seconds)
HTTP request: 10,000 milliseconds (10 seconds)

Specifying the Probe's Tolerance

The probe's tolerance determines how sensitive the probe is to failed tests—
that is, how many tests can fail before the probe reports a failure to the track.
In an actual network, some packets will always be lost; you do not want the
probe to base its status entirely on a single test.
You must specify the tolerance; it has no default setting.
