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
