Script to find memory usage on Ubuntu
This simple script will show the total memory, free memory and percentage of memory used. Have tested it on Ubuntu 14/16 but will work on CentOS as well #!/bin/bash freemem=$(($(free -m |grep "buffers/cache:"|awk '{print $4}'))) totalmem=$(($(free -m |awk 'NR==2 {print $2}'))) usage=$(($totalmem-$freemem)) echo "Memory used: $usage" echo "Total memory: $totalmem" usage=$(($usage*100 / $totalmem)) echo "Usage percentage: $usage" echo "Free memory: $freemem" echo "$TIMESTAMP $totalmem $usage $freemem"
