2.4.4. logsnoop
Display and filter system log messages.
Description
The logsnoop command can be used to display system log events. The source of the log events
can be MemLog, real-time or both MemLog followed by real-time logs.
MemLog searching will only be functioning if a LogReceiverMemory object has been configured.
Since the system log rate may be high, displaying real time logs must be done with some
caution. For this purpose, it is possible to limit the real time log display rate.
When filtering for log messages to display, there are many parameters that can be filtered on.
The most powerful filtering tool is the wildcard matching in which the charcter '*' is interpreted
as none/many characters and '?' as any single character.
It should be noted that all log filtering will have a negative effect on system performance.
Example 2.19. Show log message having 'warning' followed by 'udp' somewhere in the
message
:/> logsnoop -on -pattern=*warning*udp*
