Rules allow users to supply a detector with domain
knowledge that can improve the quality of the results.
The model detects statistically anomalous results but it
has no knowledge of the meaning of the values being modelled.
For example, a detector that performs a population analysis
over IP addresses could benefit from a list of IP addresses
that the user knows to be safe. Then anomalous results for
those IP addresses will not be created and will not affect
the quantiles either.
Another example would be a detector looking for anomalies
in the median value of CPU utilization. A user might want
to inform the detector that any results where the actual
value is less than 5 is not interesting.
This commit introduces a `custom_rules` field to the `Detector`.
A detector may have multiple rules which are combined with `or`.
A rule has 3 fields: `actions`, `scope` and `conditions`.
Actions is a list of what should happen when the rule applies.
The current options include `skip_result` and `skip_model_update`.
The default value for `actions` is the `skip_result` action.
Scope is optional and allows for applying filters on any of the
partition/over/by field. When not defined the rule applies to
all series. The `filter_id` needs to be specified to match the id
of the filter to be used. Optionally, the `filter_type` can be specified
as either `include` (default) or `exclude`. When set to `include`
the rule applies to entities that are in the filter. When set to
`exclude` the rule only applies to entities not in the filter.
There may be zero or more conditions. A condition requires `applies_to`,
`operator` and `value` to be specified. The `applies_to` value can be
either `actual`, `typical` or `diff_from_typical` and it specifies
the numerical value to which the condition applies. The `operator`
(`lt`, `lte`, `gt`, `gte`) and `value` complete the definition.
Conditions are combined with `and` and allow to specify numerical
conditions for when a rule applies.
A rule must either have a scope or one or more conditions. Finally,
a rule with scope and conditions applies when all of them apply.
Use all running nodes as unicast seeds in the rolling restart tests to
avoid a race between pinging and the tests. Without this if the tests
are too fast then when a new node comes up and pings its single
configured seed node that node *might* not have a ping from the other
running node.
I pushed a test that `assertBusy`s for a whole hour accidentally. I was
testing something and forgot to revert my local hack but caught it on
backport. This removes it.
This is much more realistic and can find more issues. This causes the
"mixed cluster" tests to be run twice so I had to fix the tests to work
in that case. In most cases I did as little as possible to get them
working but in a few cases I went a little beyond that to make them
easier for me to debug while getting them to work. My test changes:
1. Remove the "basic indexing" tests and replace them with a copy of the
tests used in the OSS. We have no way of sharing code between these two
projects so for now I copy.
2. Skip the a few tests in the "one third" upgraded scenario:
* creating a scroll to be reused when the cluster is fully upgraded
* creating some ml data to be used when the cluster is fully ugpraded
3. Drop many "assert yellow and that the cluster has two nodes"
assertions. These assertions duplicate those made by the wait condition
and they fail now that we have three nodes.
4. Switch many "assert green and that the cluster has two nodes" to 3
nodes. These assertions are unique from the wait condition and, while
I imagine they aren't required in all cases, now is not the time to
find that out. Thus, I made them work.
5. Rework the index audit trail test so it is more obvious that it is
the same test expecting different numbers based on the shape of the
cluster. The conditions for which number are expected are fairly
complex because the index audit trail is shut down until the template
for it is upgraded and the template is upgraded when a master node is
elected that has the new version of the software.
6. Add some more information to debug the index audit trail test because
it helped me figure out what was going on.
I also dropped the `waitCondition` from the `rolling-upgrade-basic`
tests because it wasn't needed.
Closes#25336
This commit adds the ability to specify a plugin from maven for a
test cluster to use. Currently, only local projects may be used as
plugins, except when testing bwc, where the coordinates of the project
are used. However, that assumes all projects always keep the same
coordinates, or are even still plugins, which is no longer the case for
x-pack. The full cluster and rolling restart tests are changed to use
this new method when pulling x-pack versions before 6.3.0.
This commit adds a general state listener to the SecurityIndexManager,
and replaces the existing health and up-to-date listeners with that. It
also moves helper methods relating to health to SecurityIndexManager
from SecurityLifecycleService.
Many tests are added with a version check so that they do not run against a
version that doesn't have the feature yet. Master is 7.0, so all tests that
do not run against 6.0+ can be removed and the version check can be removed
on all tests that always run on 6.0+.
This removes some monitoring tests that have been silenced for a long
time. These tests don't really provide any value for the upgrade suite and
they just create noise due to their occasional timing-related failures.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
