The LOGS tab displays system log events of system processes on the box layer and, if present, for each configured service. With the Log Viewer, you can inspect logs that are stored in the directory /var/phion/logs of a CloudGen Firewall or Control Center. For detailed information on the log file structure and available log files, see Logging.
The Log Viewer provides you with the following additional features while inspecting logged information:
- Hide/Show Log Tree – Hides or displays the hierarchical log file navigation tree.
- Live Mode – If set to On, shows logged information collected live.
- Set Filter – Allows you to specify special filter patterns.
Logged information is organized in a hierarchical tree structure. The triangle to the left of a tree element indicates that the element contains further subcategories. An element without a triangle contains collections of logged information.
The basic elements of the tree structure are:
- Box – Contains further containers and elements that hold logged information collected from the box level. The name of the included containers is derived from different services and sources that produce log information.
Fatal – All fatal errors that can occur on a firewall are collected in this section, in addition to the original log file. The original log file is added in the fatal log message text as a prefix.
- Reports – Reports include subcategories that contain logged information from the creation of reports. For example, Network or Statistics.
- Assigned Services – Information provided by services running on the firewall is distributed in logs under several subcategories.
For more information, see Available Log Files and Structure.
