To create a pipe symbol (|) separated values file containing data from all of the files in a directory with names ending in .log, you could use the following:
Code:
awk '
BEGIN {	OFS = "|"
}
FNR == 1 {
	d = substr(FILENAME, 1, 10)
}
$2 ~ /^[AP]M$/ && $3 != "CPU" {
	print FNR, d, $1 " " $2, $4, $6, $9
}' *.log

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

If there are files named 2015-08-14_hostname_cpu.log and 2015-08-15_hostname_cpu.log in a directory where you run the above script and each of those files contained the sample data shown in your 1st post in this thread, it produces the output:
Code:
4|2015-08-14|11:39:17 PM|0.09|0.07|99.75
5|2015-08-14|11:44:17 PM|0.04|0.03|99.92

10|2015-08-15|11:56:12 PM|0.17|0.13|99.69

I will leave it to you to redirect the output from the above script into a file you can use to load your database or pipe the output directly into a mysql statement to load your database.

mmroff

MMROFF(1)						      General Commands Manual							 MMROFF(1)

NAME

       mmroff - reference preprocessor

SYNOPSIS

       mmroff [ -x ] groff_arguments

DESCRIPTION

       mmroff is a simple preprocessor for groff, it is used for expanding references in mm, see groff_mm(7).  groff is executed twice, first with
       -z and -rRef=1 to collect all references and then to do the real processing when the reference file is up to date.

       -x     Just create the reference file. This can be used to refresh the reference file, it isn't always needed to have  accurate	references
	      and by using this option groff will only be run once.
