When using an iRule with the DOSL7::enable command and supplying a DoS profile as argument, the full path must be used. However, there is no configuration validation to support the requirement. This causes the following log message to appear repeatedly in /var/log/tmm*: notice CONF|NTCE|dosl7_update_application_conf_external:0769|could not find conf for profile crc 2884018011, name dos_profile The log message appears for every relevant request, so depending on the iRule, it might fill the log.
-- Traffic does not go through the profile specified in the iRule. -- Flooding of log messages in /var/log/tmm*. -- There is no validation to prevent the incorrect syntax.
-- Use the DOSL7::enable iRule command. -- Supply a DoS profile without the profile's full path.
Supply the profile name with its full path when using the DOSL7::enable iRule command, for example: Use this syntax: -- DOSL7::enable /Common/dos_profile Not this syntax: -- DOSL7::enable dos_profile The syntax that you use to write iRules is based on the Tool Command Language (Tcl) programming standard. Thus, you can use many of the standard Tcl commands, plus a robust set of extensions that Local Traffic Manager provides to help you further increase load balancing efficiency. Important: When referencing an object within an iRule, you must include the full path name of the object. Examples are: HTTP::class select /Common/$asm_class and set file [ ifile get "/Common/ifileURL" ]. For example: 'DOSL7::enable /Common/dos_profile' is valid, while 'DOSL7::enable dos_profile' is invalid.
