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 :(

c26ca15cc7 Make cpu load stats hierarchical for scheddebug. 2015-01-26 23:48:39 +00:00

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.

8f0f2299ab Make network fields signed integers. 
The kernel reports -1 in case of errors so it should be an allowable
returned value.

Fixes #454.

aa398c800a Add scheduler type to disk info. 
Type can be one of "none", "noop", "deadline", "cfq".
For block devices that don't use scheduler (like dm), the type will be "none".
We'll also report "none" for partitions when we start reporting those.

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.

3780075bad Handle root network device names other than eth. 
New logic ignores veth, docker, and loopback devices.

14844dbedd Remove sched stats scraping utils. 
sched_debug is getting the wrong load information. Runnable tasks list
in the output include running and sleeping tasks. We only need to look
at nr_running for each scheduling entity to figure out load. We also
don't need per-core stats.

I am going to redo these to derive per-cgroup load from nr_running.

de0e8e28eb Add percentiles utility methods. 
This is copied verbatim for our older prototype. We'll use it as
a starting point for building stats summary.

This is read once at start of cAdvisor. We can use this to report
machine state as well as return logical name for block devices in UI.
