View Log Files in Diagnostic Console

You can view one or more log files simultaneously via LogViewer, which allows browsing through several files at once to examine system activity.

The Logfile list is updated only when the associated list becomes active, as when a user enters the logfile list area, or when a new sorting option is selected. File names are preceded by a timestamp indicating either how recently the logfile has received new data or the file size of the logfile.

Timestamp and file size abbreviations:

Timestamps:

s = seconds
m = minutes
h = hours
d = days

File sizes:

B = Bytes
K = Kilobytes (1,000 bytes)
M = Megabytes (1,000,000 bytes)
G = Gigabytes (1,000,000,000 bytes)

To view log files:

Choose Operation > Admin > System Logfile Viewer.
The Logviewer screen is divided into four main areas.
- List of Logfiles currently available on the system. If list is longer than the display window, the list can be scrolled using the arrow keys.
- Logfile List sort criteria. Logfiles can be shown sort by their Full File Name, the most recently changed logfile or by the largest logfile size.
- Viewer Display options.
- Export / View selector.
Click with the mouse or use the arrow keys to navigate and press the Space bar to select a log file, marking it with an X. You can view more than one log file at a time.

To sort the Logfiles to View list:

The Sort Logfile list by options control the order in which logfiles are displayed in the Logfile to View list.

Option	Description

Individual Windows		Display the selected logs in separate sub-windows.
Merged Windows		Merge the selected logs into one display window.
Initial Buffer		Sets initial buffer or history size. 5000 is default. This system is configured to buffer all the new information that comes along.
Remember Selected Items		If this box is checked, the current logfile selections (if any) will be remembered. Otherwise, selection is reset each time a new Logfile list is generated. This is useful if you want to step thorough files.
Use Default Color Scheme		If this box is checked, some of the logfiles will be viewed with a standard color scheme. Note: multitail commands can be used to change the color scheme once the logfile(s) are being viewed.
Use Default Filters		If this box is checked, some of the logfiles will have automatic filters applied.
Export		This option packages up all the selected logfiles and makes them available via Web access so that they can be retrieved and forwarded to Raritan Technical Support. Access to the contents of this package is not available to customer. Exported logfiles will be available for up to 10 days, and then the system will automatically delete them.
View		View the selected log(s).

When View is selected with Individual Windows, the LogViewer displays:

While viewing log files, press Q, Ctrl+Q, or Ctrl+C to return to the previous screen.
You can change colors in a log file to highlight what is important. Type C to change colors of a log file and select a log from the list.
Type I for info to display system information.

Note: System load is static as of the start of this Admin Console session - use the TOP utility to dynamically monitor system resources.

To filter a log file with a regular expression:

Type e to add or edit a regular expression and select a log from the list if you have chosen to view several.
Type A to add a regular expression. For example, to display information on the WARN messages in sg/jboss/console.log log file, enter WARN and select match.
Note: This screen also shows the Default Filter Scheme for console.log, which removes most of the Java heap messages.
