Bryan Boreham	cf37e1feb4	Add __meta_kubernetes_pod_phase label in discovery (#4824 ) This lets you add a relabel rule to drop scrapes for pods which are not running. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	6 years ago
jojohappy	21e50a3f9d	Upgrade k8s client to kubernetes-1.11.0 Signed-off-by: jojohappy <sarahdj0917@gmail.com>	6 years ago
Julius Volz	219e477272	Fix some (valid) lint errors (#4287 ) Signed-off-by: Julius Volz <julius.volz@gmail.com>	6 years ago
Damien Lespiau	e64037053d	Expose controller kind and name to labelling rules Relabelling rules can use this information to attach the name of the controller that has created a pod. In turn, this can be used to slice metrics by workload at query time, ie. "Give me all metrics that have been created by the $name Deployment" Signed-off-by: Damien Lespiau <damien@weave.works>	7 years ago
Yecheng Fu	2be543e65a	Simplify some code and comments. Signed-off-by: Yecheng Fu <cofyc.jackson@gmail.com>	7 years ago
Yecheng Fu	46683dd67d	Simplify code. - Unified `send` function. - Pass InformerSynced functions to `cache.WaitForCacheSync`. - Use `Role\w+` constants instead of literal string. Signed-off-by: Yecheng Fu <cofyc.jackson@gmail.com>	7 years ago
Yecheng Fu	8ceb8f2ae8	Refactor Kubernetes Discovery Part 2: Refactoring - Do initial listing and syncing to scrape manager, then register event handlers may lost events happening in listing and syncing (if it lasted a long time). We should register event handlers at the very begining, before processing just wait until informers synced (sync in informer will list all objects and call OnUpdate event handler). - Use a queue then we don't block event callbacks and an object will be processed only once if added multiple times before it being processed. - Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService` tests to test this feature. Testing: - Use `k8s.io/client-go` testing framework and fake implementations which are more robust and reliable for testing. - `Test\w+DiscoveryBeforeRun` are used to test objects created before discoverer runs - `Test\w+DiscoveryAdd\w+` are used to test adding objects - `Test\w+DiscoveryDelete\w+` are used to test deleting objects - `Test\w+DiscoveryUpdate\w+` are used to test updating objects - `TestEndpointsDiscoveryWithService\w+` are used to test endpoints events triggered by services - `cache.DeletedFinalStateUnknown` related stuffs are removed, because we don't care deleted objects in store, we only need its name to send a specical `targetgroup.Group` to scrape manager Signed-off-by: Yecheng Fu <cofyc.jackson@gmail.com>	7 years ago
Simon Pasquier	2072bbc824	Send update when pod's IP address is empty When the pod gets evicted, its IP address becomes empty and it needs to be removed from the targets.	7 years ago
pasquier-s	bde64cf5a6	Fix Kubernetes endpoints SD for empty subsets (#3660 ) * Fix Kubernetes endpoints SD for empty subsets When an endpoints object has no associated pods (replica scaled to zero for instance), the endpoints SD should return a target group with no targets so that the SD manager propagates this information to the scrape manager. Fixes #3659 * Don't send nil target groups from the Kubernetes SD This is to be consistent with the endpoints SD part.	7 years ago
