ttyplot & systat

Me encanta esta libreria para crear para ver graficos de algunas metricas..
como CPU, Bandwidth, disk, load average entre otro..
aqui unos ejemplos que vi hace mucho tiempo en el blog de solene
y que antes usaba mucho y ahora estoy desempolvando.. hahaha

Ejemplos:

Examples list

ping
Replace test.example by the host you want to ping.
ping test.example | awk '/ms$/ { print substr($7,6) ; fflush }' | ttyplot -t "ping in ms"

cpu usage
vmstat 1 | awk 'NR>2 { print 100-$(NF); fflush(); }' | ttyplot -t "Cpu usage" -s 100

disk io
 systat -d 1000 -b  iostat 1 | awk '/^sd0/ && NR > 20 { print $2/1024 ; print $3/1024 ; fflush }' | ttyplot -2 -t "Disk read/write in kB/s"

load average 1 minute
{ while :; do uptime ; sleep 1 ; done } | awk '{ print substr($8,0,length($8)-1) ; fflush }' | ttyplot -t "load average 1"

load average 5 minutes
{ while :; do uptime ; sleep 1 ; done } | awk '{ print substr($9,0,length($9)-1) ; fflush }' | ttyplot -t "load average 5"

load average 15 minutes
{ while :; do uptime ; sleep 1 ; done } | awk '{ print $10 ; fflush }' | ttyplot -t "load average 15"

wifi signal strengh
Replace iwm0 by your interface name.
{ while :; do ifconfig iwm0 | tr ' ' '\n' ; sleep 1 ; done } | awk '/%$/ { print ; fflush }' | ttyplot -t "Wifi strength in %" -s 100

cpu temperature
{ while :; do sysctl -n hw.sensors.cpu0.temp0 ; sleep 1 ; done } | awk '{ print $1 ; fflush }' | ttyplot -t "CPU temperature in °C"

pf state searches rate
systat -d 10000 -b pf 1 | awk '/state searches/ { print $4 ; fflush }' | ttyplot -t "PF state searches per second"

pf state insertions rate
systat -d 10000 -b pf 1 | awk '/state inserts/ { print $4 ; fflush }' | ttyplot -t "PF state searches per second"

network bandwidth
Replace trunk0 by your interface. This is the same command as in my previous article.

netstat -b -w 1 -I trunk0 | awk 'NR>3 { print $1/1024; print $2/1024; fflush }' | ttyplot -2 -t "IN/OUT Bandwidth in KB/s" -u "KB/s" -c "#"
