Re: {bb} How to stop error messages due to empty /var/adm/messages file ..

[Franklin.Petersen@crown.com]

Simply  a suggestion, but this seems to plague  alot of people.

Maybe  a flag in Big Brither set to on or off, then modify the log file check to
first test for the existance of the files in the first place.

IF the flag is set to true, then if the file does not exist or is empty, it
simply ignores it and says nothing, assumably, once data is written to the log
it sees it exists and runs the test.  thus, we willingly say, that no log file
is not an issue.

IF the flag is set to false. then if the file does not exist or is empty, we
assume this is an issue like normal and the alerts go off.  In this case, we
assume you have dont something on your own to accomidate for the empty/missing
logs.

just an idea.

There are a couple of solutions to this problem:

1.   Disable this test by setting CHKMSGLEN="FALSE" in etc/bbdef.sh
     on all boxes.
2.   Modify sun's /usr/lib/newsyslog as so:

     # SMM NO EMPTY LOG FILES...
        # cp /dev/null $LOG
        echo `date "+%b %e %T"` `uname -n` newsyslog: syslog has been rotated >
$LOG

3.   Have a log message written by another means immediately upon
     logfile rotation.
