./check_log.sh
Often I needed to check log files for a keyword.
So I wrote a simple bash script to do that plus integrate with nagios and perfdata so it also generate
graphic.
The script is based on tail -f and grep on the logfile with nohup command, like:
nohup tail -f $LOG_FILE |grep --line-buffered "$VAR" > "$TMP" &

I recommend calling the check each 5 minutes.

Example usage:
./check_log.sh
