When I set the name for a Python thread, it doesn't show up on htop or ps. The ps output only shows python
as the thread name. Is there any way to set a thread name so that it shows up on system reports like them?
from threading import Thread
import time
def sleeper():
while True:
time.sleep(10)
print "sleeping"
t = Thread(target=sleeper, name="Sleeper01")
t.start()
t.join()
ps -T -p {PID} output
PID SPID TTY TIME CMD
31420 31420 pts/30 00:00:00 python
31420 31421 pts/30 00:00:00 python
First install the prctl module. (On debian/ubuntu just type sudo apt-get install python-prctl
)
from threading import Thread
import time
import prctl
def sleeper():
prctl.set_name("sleeping tiger")
while True:
time.sleep(10)
print "sleeping"
t = Thread(target=sleeper, name="Sleeper01")
t.start()
t.join()
This prints
$ ps -T
PID SPID TTY TIME CMD
22684 22684 pts/29 00:00:00 bash
23302 23302 pts/29 00:00:00 python
23302 23303 pts/29 00:00:00 sleeping tiger
23304 23304 pts/29 00:00:00 ps
Note: python3 users may wish to use pyprctl.
