cpu loadindicatormulti-coresystem-monitor
I love System Load Indicator (indicator-multiload), but it doesn't reflect the usage of the individual CPU cores, just the overall CPU usage. Sometimes I'll have an application max out a single core (ahem, Eclipse), but when I glance at the CPU usage graph, everything looks acceptable.
I know I can just open Htop, but the whole point of an application indicator is being able to get the information you want with a glance, not keystrokes. Thanks.
You can use
cat /proc/loadavg
That gives you the 3 load average numbers for the period 1, 5, and 15 minutes.
Then the number of currently running processes and then the pid of the last called process.
I don't know what you mean with the median and deviation values.
But hopefully this is a start for you.
cat /proc/meminfo
gives you memory stats.
The /proc directory could give you more infos for your needs. Just cat /proc/xxxx the file you are interested in.
cat
is just a programm to show the contents of a file to your termial. Jo can use your javaprogramm or whatever to read those files and send the values to your database.
You may use indicator-sysmonitor for such custom indicator
Install indicator-sysmonitor
sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-get update
sudo apt-get install indicator-sysmonitor
Run it
Click New:
Sensor:freq Command:awk '/cpu MHz/{printf(" %d",$4)}' /proc/cpuinfo
cpu: {cpu} mem: {mem} freq:{freq}.Save
