In the olden days, a service could exec other binaries quite +happily. Killing the primary pid of the service meant that any other +binaries launched were not necessarily killed. This mean that the +service needed to implement it's own accounting and tracking system and +there was no way to properly track to what service a given processes +belongs. + +Now with cgroups, it's possible to fully track all the processes started +by a given service and kill each of them properly when stopping the service. + +In addition it's also possible to identify to which service a given +process belongs. e.g. if something is spinning out of control you can +see it in top and then trace it back to the service itself. + +There are numerous other things that can be done with cgroups such as +imposing various limits on a given service (and any subsequent processes +it spawns). + + +Overall this is an accounting mechanism that is something very much +baked into systemd. It's an integral part of it. It's not something we +could simply "turn off" on desktops vs. servers. + + +However, this isn't really the right place to discuss this topic. + +Col + + + + +-- + +Colin Guthrie +colin(at)mageia.org +<A HREF="http://colin.guthr.ie/">http://colin.guthr.ie/</A> + +Day Job: + Tribalogic Limited <A HREF="http://www.tribalogic.net/">http://www.tribalogic.net/</A> +Open Source: + Mageia Contributor <A HREF="http://www.mageia.org/">http://www.mageia.org/</A> + PulseAudio Hacker <A HREF="http://www.pulseaudio.org/">http://www.pulseaudio.org/</A> + Trac Hacker <A HREF="http://trac.edgewall.org/">http://trac.edgewall.org/</A> +</PRE> + + + + + + + + + + + + + + + + + + + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="013253.html">[Mageia-dev] cgroup on the desktop +</A></li> + <LI>Next message: <A HREF="013325.html">[Mageia-dev] cgroup on the desktop +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#13324">[ date ]</a> + <a href="thread.html#13324">[ thread ]</a> + <a href="subject.html#13324">[ subject ]</a> + <a href="author.html#13324">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
