Monitor Component CPU and Memory Usage

MySQL Tuner provides useful diagnostics and recommendations on MySQL settings. See MySQL Tuner for more information.

To monitor the CPU and memory usage of the running components of a Moogsoft Enterprise system, you can run the following script that offers simple CPU and memory monitoring of the RabbitMQ, Socket LAM, Moogfarmd, Tomcat and MySQL processes:

#!/bin/bash

SLEEPTIME=$1

f_return_metrics() {

        PROCPID=$1
        TOPOUTPUT=`top -p $PROCPID -n1 | tail -2 | head -1 |sed 's/[^ ]\+\s\(.*\)/\1/g'`
        PROCICPU=`echo $TOPOUTPUT| awk '{print $8}'`
        if [ "$PROCICPU" == "S" ]; then PROCICPU=`echo $TOPOUTPUT| awk '{print $9}'`;fi
        PROCPCPU=`ps -p $PROCPID -o pcpu|tail -1|awk '{print $1}'`
        PROCMEM=`ps -p $PROCPID -o rss|tail -1|awk '{print $1}'`
        echo $PROCICPU,$PROCPCPU,$PROCMEM

}

#Capture PIDs
RABBITPID=`ps -ef|grep beam|grep -v grep|awk '{print $2}'`
LAMPID=`ps -ef|grep socket_lam|grep java|grep -v grep|awk '{print $2}'`
MYSQLPID=`ps -ef|grep mysqld|grep -v mysqld_safe|grep -v grep|awk '{print $2}'`
TOMCATPID=`ps -ef|grep tomcat|grep java|grep -v grep|awk '{print $2}'`
FARMDPID=`ps -ef|grep moog_farmd|grep java|grep -v grep|awk '{print $2}'`

echo "DATE,TIME,RABBITICPU(%),RABBITPCPU(%),RABBITRSS(Kb),LAMICPU(%),LAMPCPU(%),LAMRSS(Kb),FARMDICPU(%),FARMDPCPU(%),FARMDRSS(Kb),TOMCATICPU(%),TOMCATPCPU(%),TOMCATRSS(Kb),MYSQLICPU(%),MYSQLPCPU(%),MYSQLRSS(Kb)"

while [ true ]; do

  DATENOW=`date +"%m-%d-%y"`
  TIMENOW=`date +"%T"`

  RABBITMEAS=$(f_return_metrics $RABBITPID)
  LAMMEAS=$(f_return_metrics $LAMPID)
  FARMDMEAS=$(f_return_metrics $FARMDPID)
  TOMCATMEAS=$(f_return_metrics $TOMCATPID)
  MYSQLMEAS=$(f_return_metrics $MYSQLPID)
  TOMCATMEAS=$(f_return_metrics $TOMCATPID)

  echo "$DATENOW,$TIMENOW,$RABBITMEAS,$LAMMEAS,$FARMDMEAS,$TOMCATMEAS,$MYSQLMEAS"

  sleep $SLEEPTIME

done

Notes:

Notes

The script only outputs to the console, so you should redirect the output to a file for logging results.
Output is in csv format.
ICPU = "Instantaneous CPU Usage (%)"
PCPU = "Percentage of CPU usage since process startup (%)"
RSS = "Resident Set Size i.e. Memory Usage in Kb"
For CPU measurements a measure of 100% represents all of one processor so results > 100% are achievable for multi-threaded processes.
