Viewing System and Application Logs

The management console of a product has separate menus allowing you to view both system and application logs. You can also download and view log files according to your preferences, in the following ways:

• If syslog-ng is configured, download log files from the remote location where the log files are hosted using syslog-ng server. 
• If syslog-ng is not configured, download log files from the local file system (super-tenant or multi-tenant mode).

System logs display all events of a running product instance.  While system logs display log events of the entire system, the application logs allow you to select a particular application or a program and view its logs only. Application logs give a fine-grained view of system logs.

6. You can also find a certain log using the search function. Enter a keyword (or part of a keyword) and click Search. When a search criteria is given, the View drop-down list is given the value Custom.
