java - Monitor the health of weblogic server through script -


when start weblogic server, there various logs printed. structure of logging on weblogic can found on here.

i'm writing script test, whether weblogic server started successfully. need filter <error> log messages, however, 1 condition, that, following them java exception. so, particularly failure of java bean (through thrown exceptions) criteria failure of server.

i want ignore other sorts of <error> logs. there tool can in this?

update:

example of normal <error>, these types of errors should ignored:

    <may 29, 2015 5:02:44 pm ist> <notice> <stdout> <bea-000000> <|e |17:02:44 |2 |vgorade01 |correlationid=vgorade01_2_1432899124676 |'hotdirectory': /hot not exist: disabling service.>     <may 29, 2015 5:02:44 pm ist> <error> <apm> <bea-000000> <|e |17:02:44 |2 |vgorade01 |correlationid=vgorade01_2_1432899124676 |'colddirectory': /cold not exist: disabling service.>     <may 29, 2015 5:02:44 pm ist> <notice> <stdout> <bea-000000> <|e |17:02:44 |2 |vgorade01 |correlationid=vgorade01_2_1432899124676 |'colddirectory': /cold not exist: disabling service.>

example of <error>, indicate failure, notice there stacktrace of exceptions thrown:

<may 29, 2015 11:51:37 pm idt> <error> <apm> <bea-000000> <|e |23:51:37 |com.amdocs.crm.uif.orderingbackendadapter  java.lang.classnotfoundexception: com.amdocs.crm.uif.orderingbackendadapter         @ weblogic.utils.classloaders.genericclassloader.findlocalclass(genericclassloader.java:335)         @ weblogic.utils.classloaders.genericclassloader.findclass(genericclassloader.java:302)         @ java.lang.classloader.loadclass(classloader.java:424)         @ java.lang.classloader.loadclass(classloader.java:357)         @ weblogic.utils.classloaders.genericclassloader.loadclass(genericclassloader.java:180)         @ java.lang.class.forname0(native method)         @ java.lang.class.forname(class.java:190)         @ com.amdocs.uif.server.uifbackendconnector.initialize(uifbackendconnector.java:72)         @ com.amdocs.uif.server.uifserverrequestresponsemgr.initializeimpl(uifserverrequestresponsemgr.java:421)

maybe small script helps. not perfect maybe need grep wls log files full log file entries go on multiple lines:

https://github.com/freeella/grepwlslogfile

$ grepwlslogfile.pl -f /path/to/adminserver.log -s error -c "exception:"

but must use log file. stdout more problematic parse because message might span multiple lines in exception , might contain unpredictable occurrences of < , >.
