Clean up cAdvisor logging 2017-11-27 19:48:05 -08:00

2e1f0e2a08 Use a dedicated CpuLoadReader per container 
This ensures each goroutine is given its own Netlink connection, and
presumably avoids having a message destined for one goroutine read by
another goroutine.

ee8701aa97 Netlink: aggressively close cgroup fds 
Not closing the FDs manually means we have to rely on garbage collection
to run before cgroup FDs are closed. If the system is running a lot of
load probes at a high-frequency (i.e. dynamic housekeeping isn't backing
off because of load variations), we can end up hitting our FD limit due
to keeping around lots of (useless) FDs.

54bc33dd2c Lowering log level for frequent events. 
Lowering all frequent normal logs to v=3. Kubelet runs by default on
debug of v=2 and we don't want to log these events in that case.

62b02a6b94 Set of fixes for cpuload calculations. 
. Remove counting of taskgroups from scheddebug.
. Move monitoring thread 500ms ahead of other containers housekeeping.
. Rely on /proc/loadavg for root load.
. Cover up for scheddebug atomicity issues (WIP)
. Remove counting of monitoring thread.

Getting better, but still a bit farther away from ideal load :(

db3d840a9d Prefer scheddebug over netlink for cpu load. 2015-01-26 20:44:12 +00:00

67af1a1bbd Add scheddebug based cpuload reader. 
Prefer netlink based reader when available as it provides stats for
processes in state other than running (sleep, diskio, uninterruptible).

1375f451b2 Refactor netlink implementation. 
This allows us to plug in a scheddebug based interface.

cbdd96a554 Add task load stats to containers. 
The stats are only populated when cAdvisor is running outside network namespaces.
We'll add a different backend to retrieve the same data from within namespaces.
