Disclaimer: none of this is too relevant anymore. I wrote all this in 5th grade and I just uploaded it as a record.
sysmon.py is a program designed to monitor your system.
Install by navigating to the directory you have Setup.py stored in.
Then, type sudo python Setup.py in the terminal.
It will not work with python3, as it is written in python2.
To use, type sysmon into the command line.
The log is stored at /var/log/sysmon.log.
This program will work with your LINUX system provided you have the right hardware.
Note: These examples are written in Python 2.7
sudo apt-get install pip
sudo pip install psutil
Now that we have the modules installed, we can start coding.
First, create a file called usage.py.
gedit ~/usage.py
Start by importing psutil
import psutil
Then, create a function to monitor the percentage your CPU cores are running at.
def cpu_perc():
cpu_perc = psutil.cpu_percent(interval=1, percpu=True)
for i in range(len(cpu_perc)):
print "CPU Core", str(i+1),":", str(cpu_perc[i]), "%"
Let's break that down a bit, shall we?
The first line, cpu_num = psutil.cpu_percent(interval=1, percpu=True), finds the percentage that the cores in your CPU are running at and assigns it to a list called cpu_perc.
This loop right here
for i in range(len(cpu_num)):
print "CPU Core", str(i+1),":", str(cpu_perc[i]), "%"
is a for loop that prints out the current percentage of each of your CPU cores.
Let's add the RAM usage.
Create a function called ram_perc.
def ram_perc():
mem = psutil.virtual_memory()
mem_perc = mem.percent
print "RAM: ", mem_perc, "%"
psutil.virtual_memory gives a data set containing different facts about the RAM in your computer.
Next, you can add some facts about your network.
def net():
net = psutil.net_io_counters()
mbytes_sent = float(net.bytes_sent) / 1048576
mbytes_recv = float(net.bytes_recv) / 1048576
print "MB sent: ", mbytes_sent
print "MB received: ", mbytes_recv
Since psutil.net_io_counters() only gives us information about packets sent and received in bytes, some converting was necessary.
To get some information about swap space, add this function.
def swap_perc():
swap = psutil.swap_memory()
swap_perc = swap.percent
This one is pretty straightforward.
Temperature is kind of hard to do, so you may need to do some research of your own to figure out what will work with your hardware. You will have to display the contents of a certain file.
Disk usage is a lot easier than temperature. All you need to do is to pass the disk you want to monitor (i.e: /) through a certain function.
def disks():
if len(sys.argv) > 1:
for disk in range(1, len(sys.argv)):
tmp = psutil.disk_usage(sys.argv[disk])
print sys.argv[disk], "\n"
print "Megabytes total: ",
print str(float(tmp.total) / 1048576)
print "Megabytes used: ",
print str(float(tmp.used) / 1048576)
print "Megabytes free: ",
print str(float(tmp.free) / 1048576)
print "Percentage used: ",
print tmp.percent, "\n"
The original output of psutil.disk_usage is this,
>>>psutil.disk_usage('/')
sdiskusage(total=21378641920, used=4809781248, free=15482871808, percent=22.5)
but you can also just receive total, used, free, or percent.

while True:

The line temp = open("/sys/class/thermal/thermal_zone0/temp").read().strip().lstrip('temperature :').rstrip(' C') might not work with your hardware configuration.
Run this program from the command line. Pass the disks you want to monitor as arguments from the command line.
