Parse log file to insert into database
I have a log file that's created daily by this command:

Code:
sar -u 300 288 >> /var/log/usage/$(date "+%Y-%m-%d")_$(hostname)_cpu.log

It that contains data like this:

Code:
Linux 3.16.0-4-amd64 (myhostname)       08/15/2015      _x86_64_        (1 CPU)

11:34:17 PM     CPU     %user     %nice   %system   %iowait    %steal     %idle
11:39:17 PM     all      0.09      0.00      0.07      0.09      0.00     99.75
11:44:17 PM     all      0.04      0.00      0.03      0.00      0.00     99.92
11:49:17 PM     all      1.49      0.00      0.49      0.06      0.00     97.96
11:54:17 PM     all     23.27      0.00      0.51      0.05      0.03     76.14


11:56:12 PM     all      0.17      0.00      0.13      0.01      0.01     99.69
Average:        all      5.69      0.00      0.26      0.05      0.01     93.99


I'm not sure if there's a way to strip out the data I don't need before it logs to the file such as %nice, %iowait, and %steal. As well as the header and footer information. It would make the rest of this post irrelevant.

I need to ignore the first few rows and the last row. I also need to ignore any blank lines.

The only data I need to insert into the database is the time, %user, %system, and %idle data.

The table looks like this:

Code:
row_id (int) | date (date) | time (time) | hostname (varchar) | user (decimal) | system (decimal) | idle (decimal)

The log file name is YYYY-MM-DD_hostname_cpu.log format. I need to extract the date of the filename and insert into the table as well.

So far I have

Code:
cat YYYY-MM-DD_hostname_cpu.log | awk 'NR printf "%s,%s,%s\n", $4,$6,$9'

I then needed it inserted into a mysql database. I'm assuming some type of while loop would be needed here.

ds.log

ds.log(4)							   File Formats 							 ds.log(4)

NAME

       ds.log - Availability Suite data services log file

DESCRIPTION

       The  /var/adm/ds.log file contains the Availability Suite data services command log. The administration commands log activities to the file
       in the format:

	 date time product: message

       Note that when the size of the log file exceeds 10 Mbytes, ds.log is renamed  /var/adm/ds.log.bak  and a new /var/adm/ds.log file  is  cre-
       ated.

       The ds.log fields are:

       date

	   The	date format is mmm nn, where mmm  is  the local three-character abbreviation for the month and nn is the day of the month on which
	   the event occurred.

       time

	   The time of the event, in hh:mm:ss format.

       product

	   A product code that identifies which component of the data services produced the event. The code is separated  from	the  message  that
	   follows by a colon (:) and a space.

       message

	   A  message  that  can extend over  more  than  one  line describing the event that occurred. The second or following lines are not pre-
	   fixed by  the  date, time, and product code strings.

EXAMPLES

       The example below shows sample ds.log file content:

	 Jan 25 05:26:17 ii: iiboot suspend cluster tag <none>
	 Jan 25 05:32:02 ii: iiboot resume cluster tag <none>
