Java stack trace parser in awk
I want the developers to get a mail with Java stack traces on a daily bases. When something is flaged as known issue and will get a fix but mean while this does not need to get sent each dayl. This is what I got so far. It's a bash script that runs some AWK in it.

To get the files that needs to be parsed
Code:
WORK_LOG="$(find $APP_DATA/log/ -maxdepth 1 -newermt "1 days ago" ! -newermt "00:00")"

This is working. All stack traces contains "exception:" string and can be x lines untill a INFO log message accurs and we stop printing.
Code:
awk '/excepeion\:/{p=1;print;next} p&&/UTC Level INFO Scope/{p=0};p' $WORK_LOG  #>> output_test.log



Now what I need is to get rid of line containing known errors string so next part of awk don't catch them. I will give developers ability to paste strings that will be ignored into a config file
Code:
KNOW_EXCEPTION1="known error"

What I'm trying to do is get awk to remove the known exception rows before the print from here to here part.
Code:
awk '!/'"$KNOW_EXCEPTION1"'/{print $1} /excepeion\:/{p=1;print;next} p&&/UTC Level INFO Scope/{p=0};p'$WORK_LOG  >> output_test.log


This I found through google but I need to work it into what I already have and I can't get it to work.
Code:
awk '!/known error/'

jvisualvm(1)						      General Commands Manual						      jvisualvm(1)

NAME

       jvisualvm - Java Virtual Machine Monitoring, Troubleshooting, and Profiling Tool

SYNOPSIS

	       jvisualvm [ options ]

PARAMETERS

       Options,  if used, should follow immediately after the command name. Options may be in any order. For a discussion of parameters that apply
       to a specific option, see OPTIONS below.

DESCRIPTION

       Java VisualVM is an intuitive graphical user interface that provides detailed information about Java  technology-based  applications  (Java
       applications)  while  they are running on a given Java Virtual Machine (JVM(*)). The name Java VisualVM comes from the fact that Java Visu-
       alVM provides information about the JVM software visually.

       Java VisualVM combines several monitoring, troubleshooting, and profiling utilities into a single tool. For example, most of the  function-
       ality offered by the standalone tools jmap, jinfo, jstat and jstack have been integrated into Java VisualVM. Other functionalities, such as
       some of those offered by the JConsole tool, can be added as optional plug-ins.

OPTIONS

       The following option is possible when you launch Java VisualVM.

	     -J<jvm_option>
		Pass this <jvm_option> to the JVM software.

USAGE

       Java VisualVM is useful to Java application developers to troubleshoot applications and to monitor and improve  the  applications'  perfor-
       mance.  Java VisualVM can allow developers to generate and analyse heap dumps, track down memory leaks, perform and monitor garbage collec-
       tion, and perform lightweight memory and CPU profiling. Plug-ins also exist that expand the functionality of Java  VisualVM.  For  example,
       most of the functionality of the JConsole tool is available via the MBeans Tab and JConsole Plug-in Wrapper plug-ins. You can choose from a
       catalog of standard Java VisualVM plug-ins by selecting 'Tools' | 'Plugins' in the Java VisualVM menus.

       Start Java VisualVM with the following command:

       %  jvisualvm <options>

SEE ALSO

       For more details about Java VisualVM see the following pages.

	    https://visualvm.dev.java.net

	  o Java VisualVM in Java SE platform documentation @
	    http://java.sun.com/javase/6/docs/technotes/guides/visualvm/index.html

       (* The terms "Java Virtual Machine" and "JVM" mean a Virtual Machine for the Java platform.)
