Hello all,
the load on the login-server (nightshade) is quite high at the moment. One of
the problems, that cause this, is that people don't use nice. The nice-level
tells an operation system how important a program is and how much cpu-power
it should get (to simplify it).
Normal user can set a nice-level between 0 and 19. 0 is the highest, 19 the
lowest value. The default is 0. Longrunning tasks like bots should use a low
nice-level like 10.
The usage is quite easy. Just put a "nice -n 10" before your command. An
example would be
nice -n 10 python redirect.py broken
which runs the program python (that executes the redirect-script) at
nice-level 10.
More details tell the man-page of nice (man nice).
Because I know that a few of you (of corse only new users ;)) will forget
that, I wrote a little program today. The program searchs for long-running,
high-cpu-time-using programs with nice-level 0 and set nice-level 19 by force
(then it sends an eMail to inform the user). At the moment, the programm runs
in test-mode; that means it sets only a nice-level of 1 and sends an email.
If you receive such an email and think that it is wrong, please message me.
Thanks for your attention :).
Sincerly,
DaB.
