How to plot the values ​​returned by the script?

Question

Computer networks

Are there any tools that allow you to visualize the result of the script in real time ?
For example, I have a script that does something and prints values ​​to stdout:

123
120
121
124
122

Want something like:

myscript.sh | draw me

Which will draw the graph. And when a new value was received, the graph was redrawn. In fact, you need gnuplot but in real time. Approximately how STG does it, but from my values.

Answer 1

Used something like UBIQUITI NSM2
At a distance of 900m and 1300km of open space.
At a distance of 1300 meters, the transmission speed at the recipient's point reached 20Mb.
We also set these points at 200 meters, the speed loss was 30%

Answer 2

I settled on LifeGraph , making a small wrapper over it:

#!/bin/bash
JAVA_HOME='/opt/jdk1.8.0_144/'
JG_JAR='LiveGraph.2.0.beta01.Complete.jar'
JG_HOME='/opt/LiveGraph/'
DATFILE=$(mktemp)
echo "##;##" > ${DATFILE}

${JAVA_HOME}/bin/java -jar ${JG_HOME}${JG_JAR} -f ${DATFILE} -gs ${JG_HOME}session.lggs -dss ${JG_HOME}session.lgdss -dfs ${JG_HOME}session.lgdfs &
myPID=$!

trap "echo trapped; rm ${DATFILE}; kill -9 ${myPID}; exit" SIGHUP SIGINT SIGTERM
while true; do
    if ps -p ${myPID}  > /dev/null
    then
        [email protected] >>  ${DATFILE}
    else
        rm ${DATFILE}
        exit
    fi
    sleep 1
done

use something like this (if you need several charts, then the returned values ​​\u200b\u200bmust be separated by a semicolon (123;323;2344;22)

LiveGraph.sh snmpget -v2c -O vqn -cpublic  192.168.45.5 .1.3.6.1.4.1.42.2.145.3.163.1.1.2.11.0
