Chapter 6 Configuring Real Servers and Server Farms
Configuring Health Monitoring
To configure probe headers and expect statuses for HTTPS probes, see the following topics:
• Configuring Headers for HTTP and HTTPS Probes, page 6-66
• Configuring Health Monitoring Expect Status, page 6-67
IMAP Probe Attributes
Note Click More Settings to access the additional attributes for the IMAP probe type. By default, ACE
appliance Device Manager hides the probe attributes with default values and the probe attributes which
are not commonly used.
Password Enter the password to be used for authentication on the real server. Valid
entries are unquoted text strings with a maximum of 64 characters.
Reenter the password in the Confirm field.
Expect Regular
Expression
Enter the expected response data from the probe destination. Valid entries
are text strings (quotes allowed) with a maximum of 255 characters.
Expect Regex Offset Enter the number of characters into the received message or buffer where the
ACE is to begin looking for the string specified in the Expect Regular
Expression field. Value entries are integers from 1 to 4000.
Hash Check the Hash check box to indicate that the ACE is to use an MD5 hash
for an HTTP GET probe. Clear this check box to indicate that the ACE is not
to use an MD5 hash for an HTTP GET probe.
Hash String This field appears if the Hash check box is selected.
Enter the 32-bit hash value that the ACE is to compare with the hash that is
generated from the HTTP page sent by the server. If you do not provide this
value, the ACE generates a value the first time it queries the server, stores
this value, and matches this value with other responses from the server. A
successful comparison causes the probe to maintain an Alive state.
Enter the MD5 hash value as a quoted or unquoted hexadecimal string with
16 characters.
Ignore Certificate
Expiration
Check the Ignore Certificate Expiration check box to configure the probe to
ignore the certificate expiration date so the probe does not affect ACE
functionality when the certificate has expired. Uncheck the check box to
configure the ACE not to ignore the certificate expiration date.
