Xuewei Zhang cf6624661a Update READMEs 2019-06-13 00:51:17 -07:00
Xuewei Zhang 7ad5dec712 Add disk metrics support. 2019-06-13 00:51:17 -07:00
Xuewei Zhang 23dc265971 Add Prometheus exporter. 2019-06-13 00:51:17 -07:00
Xuewei Zhang a07176073a Add existing monitors into the problem daemon registration hook. 2019-06-13 00:51:17 -07:00
Xuewei Zhang 63f0e35e56 Implement dynamic problemdaemon registration and initialization. 
Added package problemdaemon. All future problem daemons should be
registered by calling problemdaemon.register().

CLI interfaces will be automatically generated for all registered
problem daemons in the form of "--config.DAEMON_NAME"
 2019-06-12 18:29:18 -07:00
Xuewei Zhang 5814195ad5 Move apiserver-reporting logic into k8s_exporter. 
Added CLI option "enable-k8s-exporter" (default to true). Users can use
this option to enable/disable exporting to Kubernetes control plane.

This commit also removes all the apiserver-specific logic from package
problemdetector.

Future exporters (e.g. to local journald, Prometheus, other control
planes) should implement types.Exporter interface.

Xuewei Zhang c6c4e80c9d Remove TestGoroutineLeak unit tests. 
We are seeing some flakes on these tests because some goroutine
fluctuation:
https://github.com/kubernetes/node-problem-detector/pull/275#issuecomment-499306727

Removing the tests, as it's robust to test leakage in a soak/stress
test, rather than unit test.

Euan Kemp 9c23921c11 logwatchers/kmsg: add initial kmsg watcher impl 
This adds a logwatcher which is able to parse kernel messages directly
from the /dev/kmsg interface. This supports any modern linux distro,
while also avoiding any dependency on libraries (e.g. as journald
needs).

Fix kernel monitor issues

Random-Liu d281cb8a15 Fix kernel monitor issues: 
* Change `unregister_netdevice` to be an event to fix #47.
* Change `KernelPanic` to `KernelOops` because we can't handle kernel
panic currently.
* Use system boot time instead of "StartPattern" to fix #48.
