 +
The rational for behind this is :
 +
You have a database / source of information that you would like to graph. In this instance, I needed to see in fairly real-time, the number of http processes as well as the size of these processes.
 +
 +
It could be applied to a multitude of scenarios.
 +
 +
==Getting Started==
 +
 +
1.Prepare the collection of the relevant parameters that you want to monitor ( in this case, http stats )
 +
create a shell script:
 +
#/usr/bin
 +
 +
while true
 +
do
 +
LOG=outlog.txt
 +
OUTPUT=$(ps -ylC httpd | awk '{x += $8;y += 1} END {print "Apache Memory Usage (MB): "x/1024; print ":Average Proccess Size (MB): "x/((y-1)*1024)}' && echo -n ':Apache Processes: ' && ps -C httpd --no-headers | wc -l  )
 +
#DAY=$(date +"%F %H:%M:%S")
 +
DAY=$(date +"%F"+"%T")
 +
now=$(date +'%Y-%m-%d %H:%M:%S')
 +
 +
##echo $OUTPUT \'$DAY\'
 +
echo $OUTPUT \'$DAY\' | awk  '{print "INSERT INTO performance (mem_used, process_size, processors_used,period) VALUES  ( "$5", "$10", "$13", "$14" );"}' | mysql --user=username --password=password database_name
 +
sleep 120
 +
done
