Bash does not overwrite IFS, but it does always set it to the default in a new shell. It does not take its value from the environment. If you want something other than the default in a shell script, you must set it explicitly. (This is the same behaviour as ksh.)

NAME
pmdamysql - MySQL database PMDA DESCRIPTION
pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a running MySQL database. INSTALLATION
pmdamysql uses a configuration file from (in this order): o /etc/pcpdbi.conf o $PCP_PMDAS_DIR/mysql/mysql.conf This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl, namely: o database name (see DBI(3) for details) o database user name o database pass word Once this is setup, you can access the names and values for the mysql performance metrics by doing the following as root: # cd $PCP_PMDAS_DIR/mysql # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/mysql # ./Remove pmdamysql is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. Binary Status values in text Some of the status values are in the form of YES/NO or ON/OFF. Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num extension and the values of 1 (YES/ON) or 0 (NO/OFF). Eg: o mysql.slave_status.slave_io_running o mysql.slave_status.slave_io_running_num FILES
/etc/pcpdbi.conf configuration file for all PCP database monitors $PCP_PMDAS_DIR/mysql/mysql.conf configuration file for pmdamysql $PCP_PMDAS_DIR/mysql/Install installation script for the pmdamysql agent $PCP_PMDAS_DIR/mysql/Remove undo installation script for the pmdamysql agent $PCP_LOG_DIR/pmcd/mysql.log default log file for error messages from pmdamysql SEE ALSO
