Viper Online Backup Helpdesk

There are event logs, however this application only creates a log when an error occurs. In addition to the error, the application saves the 20debug/info/warning messages prior to the error. This helps identify the context to the event in question and aids in troubleshooting.
 

 INTRO:

 There 4 kinds of logs messages:

1. None ­– do not write any kind of logs.
2. Debug – writes all kinds of log info while application running. Writes the parameters of the method calls, executed SQL scripts, Web method call results and parameters. This level harms the performance of application as it’s used only for development purposes. This level is the most informative.
3. Info – represents application lifetime process. Say for example : ‘INFO - Authenticating user helloworld@viperonlinebackup.com...’; ‘INFO - Starting backup’
4. Warn – represents the warning messages that can be handled with application: ‘WARN – Internet connection is not established….’; ‘WARN – helloworld@viperonlinebackup.com has expired…’
5. Error – errors that occurred while app execution, that cannot be handled with application.

 The stack of write priorities is next (from top to down):
 

 Debug

 Info

 Warn

 Error
 

if I set ‘debug’ – it will also write Info/warn/error

if I set ‘info’ – it will also write warn/error

if I set ‘warn’ – it will also write error

if I set ‘error’ – it will write error (+ 20 last debug/info/warn messages)
