This should be the way forward when importing libraries in jsonnet. It's
closer to how Go imports look and makes it more obvious where packages
live.
This is not breaking anything, as the old imports were already symlinks
to the now directly used directories.

The counter is only increased when tsdb.Open() is called which
Prometheus does only once in its lifetime (when it initializes). If the
corruption can't be recovered, tsdb.Open() returns an error and
Prometheus exits. Hence the metric is either 0 (no corruption) or 1
(corruption detected and repaired). If the latter, the alert isn't
actionable and the only way to resolve it is to restart Prometheus which
would reset the counter.

* *: bump gRPC dependencies
This change updates the gRPC dependencies to more recent versions:
* github.com/gogo/protobuf => v1.2.0
* github.com/grpc-ecosystem/grpc-gateway => v1.6.3
* google.golang.org/grpc => v1.17.0
In addition scripts/genproto.sh leverages Go modules information instead of
hardcoding SHA1 commits. This ensures that the code is generated from

As alertmanager needs to be configured in the config file in Prometheus 2, I think it is useful to have it in the example config.
Also renamed the rules in the example config so they are explicitely yml files.

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.

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.
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.
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+)
This removes legacy support for specific remote storage systems in favor
of only offering the generic remote write protocol. An example bridge
application that translates from the generic protocol to each of those
legacy backends is still provided at:
documentation/examples/remote_storage/remote_storage_bridge
See also https://github.com/prometheus/prometheus/issues/10
The next step in the plan is to re-add support for multiple remote
storages.
In preparation for removing specific remote storage implementations,
this offers an example of how to achieve the same in a separate process.
Rather than having three separate bridges for OpenTSDB, InfluxDB, and
Graphite, I decided to support all in one binary.
For now, this is in the example documenation directory, but perhaps we
will want to make a first-class project / repository out of it.
