More detail about exposed functions here , i implemented all of the functions provided by the module.
Plugin contains just expressions which provide some system basic system info.
I added seven more expressions:
loadavg1; Returns value containing the 1 minute load average.
loadavg5; Returns value containing the 5 minute load average.
loadavg15; Returns value containing the 15 minute load average.
cpusnum; Returns number of cpu's.
cpusmodel; Returns model of cpu.
cpusString; Returns an string containing array of objects containing information about each CPU/core installed: model, speed (in MHz), and times (an object containing the number of CPU ticks spent in: user, nice, sys, idle, and irq).
networkInterfacesString; Get a string containing list of network interfaces.
Please note that some expressions are available but they returns arrays or objects, not strings or numbers:
loadavg - Returns an array containing the 1, 5, and 15 minute load averages. (exposed with loadavg1, loadavg5, loadavg15 expressions)
cpus - Returns an array of objects containing information about each CPU/core installed (exposed some data with cpusmodel and cpusnum expressions, get a string representation using cpusString )
networkInterfaces - Get a list of network interfaces; returns an object (exposed with networkInterfacesString, get a string representation)
Enjoy playing and testing,
