FengyunPan2	34a8b1fd9f	Add helpful log for checking cgrop path ... Currently I just get 'xxx cgroup does not exist', but I don't know which path has missed. Let's add log for it.	2018-09-25 10:10:12 +08:00

Filipe Brandenburger	b230fb8ac4	Use a []string for CgroupName, which is a more accurate internal representation ... The slice of strings more precisely captures the hierarchic nature of the cgroup paths we use to represent pods and their groupings. It also ensures we're reducing the chances of passing an incorrect path format to a cgroup driver that requires a different path naming, since now explicit conversions are always needed. The new constructor NewCgroupName starts from an existing CgroupName, which enforces a hierarchy where a root is always needed. It also performs checking on the component names to ensure invalid characters ("/" and "_") are not in use. A RootCgroupName for the top of the cgroup hierarchy tree is introduced. This refactor results in a net reduction of around 30 lines of code, mainly with the demise of ConvertCgroupNameToSystemd which had fairly complicated logic in it and was doing just too many things. There's a small TODO in a helper updateSystemdCgroupInfo that was introduced to make this commit possible. That logic really belongs in libcontainer, I'm planning to send a PR there to include it there. (The API already takes a field with that information, only that field is only processed in cgroupfs and not systemd driver, we should fix that.) Tested by running the e2e-node tests on both Ubuntu 16.04 (with cgroupfs driver) and CentOS 7 (with systemd driver.)	2018-05-01 08:29:06 -07:00
Derek Carr	4afc0c8052	kubelet ignores hugepages if hugetlb is not enabled	2018-02-05 13:07:59 -05:00
Davanum Srinivas	ecd6361ff0	Set pids limit at pod level ... Add a new Alpha Feature to set a maximum number of pids per Pod. This is to allow the use case where cluster administrators wish to limit the pids consumed per pod (example when running a CI system). By default, we do not set any maximum limit, If an administrator wants to enable this, they should enable `SupportPodPidsLimit=true` in the `--feature-gates=` parameter to kubelet and specify the limit using the `--pod-max-pids` parameter. The limit set is the total count of all processes running in all containers in the pod.	2018-01-11 21:22:38 -05:00
Jing Xu	a66ee2eb3f	Add pod-level metric for CPU and memory stats ... This PR adds the pod-level metrics for CPU and memory stats. cAdvisor can get all pod cgroup information so we can add this pod-level CPU and memory stats information from the corresponding pod cgroup	2017-11-22 09:25:23 -08:00
