Pulling out entries from file based on IP - awk
i have several lines in a file that looks like this:


Code:
2013-03-23 19:02:33,122 DiscoverManager [Discover-15] WeblogicApplication-10.111.112.119-7400 FAILURE

i'm monitoring this file for strings that contain FAILURE. but i've been getting a lot of alerts that just aren't actionable. so i need another way around this.

each line has an IP and a port number, which is what i bolded above. i'm wondering, is there a way to do something like this:
  • if 10 or more entries for any specific IP are found in the log, AND each of the entry is for different port numbers, then alert?

my problem is, there isn't a list of known IPs or ports. any IP can be thrown in the file. so i'm curious if what i'm thinking is possible? i'm guessing awk can be used for this?

i was using a variation of this command to get a count:

Code:
awk '/FAILURE/ && /FAILURE/ {++c}c>=10 -1{o=$0 RS $0 RS $0; print o; c=0}' file

and i was using this to show me the actual offending lines from the file:

Code:
awk '/FAILURE/ && /FAILURE/' file

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
