With https://github.com/elastic/beats/pull/7075 Beats introduces state reporting for X-Pack Monitoring. The data sent up to Elasticsearch ends up stored in the following format.
```
"beats_state": {
"timestamp": "2018-07-05T07:21:03.581Z",
"state": {
"module": {
"count": 1,
"names": [
"http"
]
}
},
"beat": {
"uuid": "594039b5-6353-4d78-9bad-778ecc0fe83f",
"type": "metricbeat",
"version": "7.0.0-alpha1",
"name": "ruflin",
"host": "ruflin"
}
}
```
This PR adds the new fields to the template.
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!
= Open source
The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.
The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.
= Location of the new files
We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.
We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.
= Location of the API in the REST client
We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.
`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.
= Jars, jars everywhere!
This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.
In that followup I'll address javadoc issues as well.
= Breaking-Java
This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.

Fix TransportChangePasswordActionTests
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
Add hard limit to the number of items
a filter may have. This serves to protect
from excessive overhead due to the filters
taking too much memory or lookups becoming
too expensive.
This change adds stats about forecasts, to the jobstats api as well as xpack/_usage. The following
information is collected:
_xpack/ml/anomaly_detectors/{jobid|_all}/_stats:
- total number of forecasts
- memory statistics (mean/min/max)
- runtime statistics
- record statistics
- counts by status
_xpack/usage
- collected by job status as well as overall (_all):
- total number of forecasts
- number of jobs that have at least 1 forecast
- memory, runtime, record statistics
- counts by status
Fixes#31395
* Default resolveFromHash to Hasher.NOOP
This changes the default behavior when resolving the hashing
algorithm from unrecognised hash strings, which was introduced in
#31234
A hash string that doesn't start with an algorithm identifier can
either be a malformed/corrupted hash or a plaintext password when
Hasher.NOOP is used(against warnings).
Do not make assumptions about which of the two is true for such
strings and default to Hasher.NOOP. Hash verification will subsequently
fail for malformed hashes.
Finally, do not log the potentially malformed hash as this can very
well be a plaintext password.

Support multiple system store types
When falling back to using the system keystore and - most usually -
truststore, do not assume that it will be a JKS store, but deduct
its type from {@code KeyStore#getDefaultKeyStoreType}. This allows
the use of any store type the Security Provider supports by setting
the keystore.type java security property.
Make password hashing algorithm/cost configurable for the
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are
whitelisted and can be selected in the relevant setting.

Closes#31324. The issue has full context in comments.
With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.

This creates a YAML test "features" that indices if the cluster being
tested has xpack installed (`xpack`) or if it does *not* have xpack
installed (`no_xpack`). It uses those features to centralize skipping
a few tests that fail if xpack is installed.
The plan is to use this in a followup to skip docs tests that require
xpack when xpack is not installed. We *plan* to use the declaration
of required license level on the docs page to generate the required
`skip`.
Closes#30933.

TransportAction currently contains 2 doExecute methods, one which takes

task. This commit combines these methods, in favor of just always
assuming a task is present.
This adds an api to allow updating a filter:
POST _xpack/ml/filters/{filter_id}/_update
The request body may have:
- description: setting a new description
- add_items: a list of the items to add
- remove_items: a list of the items to remove
This commit also changes the PUT filter api to
error when the filter_id is already used. As
now there is an api for updating filters, the
put api should only be used to create new ones.
Also, updating a filter results into a notification
message auditing the change for every job that is
using that filter.
According to RFC 7617, the Basic authentication scheme name
should not be case sensitive.
Case insensitive comparisons are also applicable for the bearer
tokens where Bearer authentication scheme is used as per
RFC 6750 and RFC 7235
Some Http clients may send authentication scheme names in
different case types for eg. Basic, basic, BASIC, BEARER etc.,
so the lack of case-insensitive check is an issue when these
clients try to authenticate with elasticsearch.
This commit adds case-insensitive checks for Basic and Bearer
authentication schemes.
Closes#31486
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
- POST _xpack/index_lifecycle/_stop
- issues a request to be placed into STOPPED mode (maintenance mode).
This is not immediate, since we must first verify that
it is safe to go from STOPPING -> STOPPED.
- POST _xpack/index_lifecycle/_start
- issues a request to be placed back into RUNNING mode (immediately)
- GET _xpack/index_lifecycle/_status
- get back the current mode our lifecycle management is in
- update task was hardened to support uninstalled metadata
- if no metadata is installed, the start/stop actions will install metadata
and proceed to try and change it (default start mode is RUNNING)
- rename MAINTENANCE -> STOPPED, MAINTENANCE_REQUESTED -> STOPPING, NORMAL -> RUNNING
follow-up to #31164.
Indices that are rolled over preserve their origin index.lifecycle.date
as the time the index was created. Although this is also fine, it would
make more sense to start the timer for moving to the warm phase from the
time it was rolled over so that we capture the time elapsed from the
latest data, as opposed to when the index was created.
This commit adds an extra step within the RolloverAction that
extracts the index.creation_date of the newly created index from the RolloverStep
and sets that as the index.lifecycle.date of the rolled-over index that is
waiting for its next phase.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.

Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
The changes made to disable security for trial licenses unless security
is explicitly enabled caused issues when a 6.3 node attempts to join a
cluster that already has a production license installed. The new node
starts off with a trial license and `xpack.security.enabled` is not
set for the node, which causes the security code to skip attaching the
user to the request. The existing cluster has security enabled and the
lack of a user attached to the requests causes the request to be
rejected.
This commit changes the security code to check if the state has been
recovered yet when making the decision on whether or not to attach a
user. If the state has not yet been recovered, the code will attach
the user to the request in case security is enabled on the cluster
being joined.
Closes#31332
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.

GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.
Relates #30603
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
This PR introduces a concept of a maintenance mode for the
lifecycle service. During maintenance mode, no policies are
executed.
To be placed into maintenance mode, users must first issue a
request to be placed in maintenance mode. Once the service
is assured that no policies are in actions that are not to be
interrupted (like ShrinkAction), the service will place itself
in maintenance mode.
APIs to-be introduced:
- POST _xpack/index_lifecycle/maintenance/_request
- issues a request to be placed into maintenenance mode.
This is not immediate, since we must first verify that
it is safe to go from REQUESTED -> IN maintenance mode.
- POST _xpack/index_lifecycle/maintenance/_stop
- issues a request to be taken out (this is immediate)
- GET _xpack/index_lifecycle/maintenance
- get back the current mode our lifecycle management is in
