Hi guys:
I have to write a script that monitors the system logfiles for
certain words and send alerts if it finds one. I have a skeleton perl script
that does some of the logic. However, is it possible to run a perl script as a
daemon rather than running it via cron every 1 sec so that the log files can
be monitored at realtime? Also, since the messages might appear multiple
times, any ideas how I can send alerts only on the newer log messages ? Any
pointers would be helpful. Below is my Perl script.
-------------------
$LOG="/var/adm/messages";
if (-e $LOG && -s $LOG) {
open (FILE, $LOG) ||
die "Cannot open";
while (<FILE>) {
if (/panic/|/warning/) {
< send alerts here >;
}
}
}
else {
print "$LOG file doesn't
exist\n";
}
close (FILE);
---------------------------------
Thanks in
advance and appologize for the slightly offtopic post. Will summarize
GR
ps:
This question was asked by Ert Werr a few weeks back. Repeated requests by me
didn't result in a summary. Hence, I had to post this again here.
