Nexpose : Vulnerability Tracking : Host Details Page : Attempts Tab

Attempts Tab
If Metasploit Pro has run any module against the host, you can view the results from the Attempts tab. The Attempts tab shows when the modules were run, the person who launched the module, the result code for the module run, and the reason the module failed or succeeded.
For example, you may want to view the Attempts tab if you want to find a list of modules that Metasploit Pro has run against a particular port or service.
Result Codes
A result code provides the reason why a module run was unsuccessful.
The following table describes the result codes that are available for an exploit attempt:
Indicates that Metasploit Pro could not determine if the module ran successfully or failed.
Indicates that Metasploit Pro could not determine if the module ran successfully or failed.
