Looking for a CLI command to see last 20 logging events in a FPR-2110.

I had no chance working with FTD; can you employ show log | tail -20 maybe? or tail /log_path?

NX-OS on DataCenter SWs has tail function after pipe, it's addictive!

Thanks, i tried the tail command the other day no luck, i think i found out what's  going on with my logging, looks like some kind of debugging left on.....now trying to figure which logging it is.

Thanks.

Can you share logging config that you use now?

The "pigtail" utility may help. Switch to expert mode from the cli and sudo su to run it.

pigtail v1.03 (05/13/2015)
--------------------------------------------------------------------------------------------------------------
NAME
    pigtail -- continuously display FireSIGHT management console (and device) logs as the files are written

SYNOPSIS
    pigtail [-d] [-o] [-h] [-raw] [-n number] [-outfile file] [-history start time end time] [-break regex] [-trigger regex command] [filetype ...]

DESCRIPTION

       .-~~~~-. |\\_     pigtail parses, reformats, and displays the contents of several log files
    @_/        /  oo\_   to the screen, updating the display whenever additional lines are added to any of 
      |    \   \   _(")  the log files.  pigtail also colorizes the output so it is easier to discern between 
       \   /-| ||'--'    lines from different log files.  By default it normalizes timestamps, removes some 
        \_\  \_\\        extraneous information, and reformats certain lines to improve readability.
    
    These are the keywords and associated log files that pigtail supports:
