| - | ====== Load logger ====== | ||
| - | A simple bash script to log the datetime and system load to a file every minute. I wanted something that didn't rely on having any other programs installed. | ||
| - | |||
| - | It saves data in the following format: Server ID, Date/Time, CPU usage (%), CPU max, Memory Total (Mb), Memory Used (Mb), Memory Free (Mb), Memory Shared (Mb), Memory Buffered/Cached (Mb), Memory Available (Mb), 1 minute load average, 5 minute load average, 15 minute load average, process count, network usage (one column per interface in the format [interface name, received bytes, transmitted bytes]) | ||

| - | #!/bin/bash | ||
| - | ID='SERVER1' | ||
| - | CPU_COUNT=`cat /proc/cpuinfo | grep processor | wc -l` | ||
| - | MAX_CPU=$(($CPU_COUNT * 100)) | ||
| - | printf -v date '%(%Y-%m-%d %H:%M:%S)T' -1 | ||
| - | CPU_USAGE=`ps -ax -h -o pcpu | paste "-sd+" | bc` | ||
| - | MEM_USAGE=`free -m | grep 'Mem:' | awk -v OFS="," '{print ($2,$3,$4,$5,$6,$7)}'` | ||
| - | LOAD_AVG=`awk -v OFS="," '{split($4,arr,"/")} {print $1,$2,$3,arr[2]}' /proc/loadavg` | ||
