Log Viewer provides these options from the top of the right pane.
Reload—Refreshes the log. You can view logs while they are open for writing.
Automatic—Refreshes the log about every 6 seconds, automatically.
Resolve addresses—Displays DNS names instead of numeric IP addresses.
Note: Address resolution may be slow, since it can require multiple DNS requests per address. Results are cached until you close the Log Viewer.
Slider for Message Level Control—Filters the messages by Severity level.
Severe messages are highlighted in red. Warnings are highlighted in yellow.
Search—Type a partial search string into the text box to search the message field for matching strings. Log Viewer displays only the results with that string.
Click the X to clear the text field and view all messages for selected level control.
