How to get df output into MySQL using bash?
Hi All,

I want to run some commands and get the output into a mysql database.

I want to run the df cmd into a text file, then import it into my db sysinfo using a bash script.
My table "df" has the following 9 fields:

server, filesystem, size, used, available, useperc, mounted, date, time

cmd for df creates it in a comma separated output.
Code:
df -k | tr -s " " | sed 's/ /, /g' | grep -v Filesystem > df.txt

bash script for loading data:
Code:
#!/bin/bash
/usr/bin/mysql --user=<user> --password=<password> --database=sysinfo<<EOFMYSQL

load data local infile 'df.txt'  INTO TABLE df fields terminated by '\,' LINES
TERMINATED BY '\n'; 
EOFMYSQL

Unfortunately this is not working and I only get the first line imported.

Can some one show me how to fix this script, I think it may be to do with the line terminators but can't find a solution.

I would also like to prepend the host name for field 1 and the date and time in the last 2 fields.

I'm very new to sql would really apreciate some help and advice.

pmdamysql

PMDAMYSQL(1)						       Performance Co-Pilot						      PMDAMYSQL(1)

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
