Forum discussion
This how-to can be discussed on the forums here
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
