Bryan Boreham	1e3fef6ab0	scraping: limit detail on dropped targets, to save memory (#12647 ) It's possible (quite common on Kubernetes) to have a service discovery return thousands of targets then drop most of them in relabel rules. The main place this data is used is to display in the web UI, where you don't want thousands of lines of display. The new limit is `keep_dropped_targets`, which defaults to 0 for backwards-compatibility. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago

Johannes 'fish' Ziemke	70f3d1e9f9	k8s: Support discovery of ingresses (#3111 ) * k8s: Support discovery of ingresses * Move additional labels below allocation This makes it more obvious why the additional elements are allocated. Also fix allocation for node where we only set a single label. * k8s: Remove port from ingress discovery * k8s: Add comment to ingress discovery example	7 years ago
Felicity	f30b10223a	documentation: update Kubernetes example for 1.7 (#2918 ) Kubernetes 1.7+ no longer exposes cAdvisor metrics on the Kubelet metrics endpoint. Update the example configuration to scrape cAdvisor in addition to Kubelet. The provided configuration works for 1.7.3+ and commented notes are given for 1.7.2 and earlier versions. Also remove the comment about node (Kubelet) CA not matching the master CA. Since the example no longer connects directly to the nodes, it doesn't matter what CA they're using.

Svend Sorensen	94a3e863e4	Document what ports are scraped by default in k8s example The Kubernetes pod SD creates a target for each declared port, as documented: https://prometheus.io/docs/operating/configuration/#pod > The pod role discovers all pods and exposes their containers as targets. For > each declared port of a container, a single target is generated. If a > container has no specified ports, a port-free target per container is created > for manually adding a port via relabeling. This results in the default port being the declared port, or no port if none are declared.	8 years ago
Stephen Soltesz	3f29324e04	Fix kubernetes host:port relabel regex. This change corrects a bug introduced by PR https://github.com/prometheus/prometheus/pull/2427 The regex uses three groups: the hostname, an optional port, and the prefered port from a kubernetes annotation. Previously, the second group should have been ignored if a :port was not present in the input. However, making the port group optional with the "?" had the unintended side-effect of allowing the hostname regex "(.+)" to match greedily, which included the ":port" patterns up to the ";" separating the hostname from the kubernetes port annotation. This change updates the regex for the hostname to match any non-":" characters. This forces the regex to stop if a ":port" is present and allow the second group to match the optional port.	8 years ago
Stephen Soltesz	0b1790ee44	Match addresses with or without declared ports. This change updates port relabeling for pod and service discovery so the relabeling regex matches addresses with or without declared ports. As well, this change uses a consistent style in the replacement pattern for the two expressions. Previously, for both services or pods that did not have declared ports, the relabel config regex would fail to match: __meta_kubernetes_service_annotation_prometheus_io_port regex: (.+)(?::\d+);(\d+) __meta_kubernetes_pod_annotation_prometheus_io_port regex: (.+):(?:\d+);(\d+) Both regexes expected a <host>:<port> pattern. The new regex matches addresses with or without declared ports by making the :<port> pattern optional. __meta_kubernetes_service_annotation_prometheus_io_port __meta_kubernetes_pod_annotation_prometheus_io_port regex: (.+)(?::\d+)?;(\d+)	8 years ago
