Using the following code, I can get the memory consumption of a give process in MiB:
def memory_usage_psutil():
# return the memory usage in MB
import psutil
process = psutil.Process(os.getpid())
mem = process.get_memory_info()[0] / float(2 ** 20)
return mem
How can I change this to return the percentage of memory consumption?
Update: I need to get the current value of %MEM
column when executing the top
command in terminal for a specific process.
Example: I need this function to return 14.2 for the process id of VirtualBox process.
use process.memory_percent()
This agrees with top. In the test script below, you can change the argument to the range function defining the consume_memory
array, which is only there to use up memory for testing, and both python output and top output will match:
import os
import psutil
def memory_usage_psutil():
# return the memory usage in percentage like top
process = psutil.Process(os.getpid())
mem = process.memory_percent()
return mem
consume_memory = range(20*1000*1000)
while True:
print memory_usage_psutil()
import os
import sys
import psutil
for id in psutil.pids():
p = psutil.Process(id)
if ( p.name() == 'firefox' ):
print("id of firefox process : " + str(id))
mem = p.memory_percent()
print ("Memory Perentage for Firefox process is " + str(mem))
