Fix panic when trying to add key to nil map

71a8e99d1f Fix panic when trying to add key to nil map
Bug was introduced trying to solved the following issue:
> When scenarios where two HPAs reference the same object but have
different metric calculation (e.g. ingresses with different weights),
kube-metrics-adapter calculates the two metrics but always overrides
one of the metrics when saving it to the store.

This commit fixes a issue where without the added `return` the system
was continuing in an invalid states where `labels2metric` wasn't
properly initialized, causing the system to panic.

2ccd6903d9 Merge pull request #376 from zalando-incubator/custommetricsselector
Use labels hash in the custom metrics store and metrics store 💅
2021-11-25 10:24:44 +01:00
f58db31f98 Define stronger types for metrics store
The metrics store, both the custom and external one, make heavy usage of
maps of strings to strings. This leads to a presumable confusing or at
least hard to read codebase.

This commit tries to increase readability and maintainability of the
metric stores by using custom types. This commit has no effect in
performance or functionality, it's pure aesthetics.

0bf8f5dd0f Use labels hash in the custom metrics store
The current implementation of the metrics store for custom metrics uses
just the object name as key. When scenarios where two HPAs reference the
same object but have different metric calculation (e.g. ingresses with
different weights), kube-metrics-adapter calculates the two metrics but
always overrides one of the metrics when saving it to the store.

This commit implements the use of a labels hash in the custom metrics
store. This way, metrics are identified not just by the referenced
object, but also by its selectors.

Make the number of ramp steps configurable
2021-10-25 10:21:32 +02:00
fd4ead837e Make the number of ramp steps configurable
In #371 we introduced steps to make the scaling up possible even when
the HPA forces a 10% change. The problem is that 10% might not be
sufficient for some specific scaling scenarios.

For example, a an application targeting 12 pods and using a
ScalingSchedule with the value of 10000 to achieve that, will require a
target of 833. With 10 ramp steps the 90% bucket will return a metric of
9000 and the HPA calculates (9000/833) 10.8 pods, rounding to 11 pods.
Once the metric reaches the time to return 100% it will won't be
effective, since the change of the current number of pods (11) and the
desired one (12) is less than 10%.

This commit does not try to tackle this problem completely, since the
10% rule is not fixed, might change among different clusters and is also
dependent on the value given to each ScalingSchedule. Therefore, this
commit makes the number of ramp steps configurable via the
`--scaling-schedule-ramp-steps` config flag, defaulting to 10.

Use 10 buckets on ScalingSchedule ramp-up/down
2021-10-01 10:39:57 +02:00
8fe330941a Use 10 buckets on ScalingSchedule ramp-up/down
The HPA has a feature to do not scale up and down when the change in the
metric is less than 10%:

> We'll skip scaling if the ratio is sufficiently close to 1.0 (within a
> globally-configurable tolerance, from the
> `--horizontal-pod-autoscaler-tolerance` flag, which defaults to 0.1.

It could lead to pods scaling up to 10% less than the target for
ScalingSchedules and then not scaling to the actual value if the metric
calculated before was less than 10% of the target.

This commit uses 10 fixed buckets for scaling, this way we know the
metric returned during a scaling event is at least 10% more than a
previous one calculated during the period of ramp up. The same is valid
for the scaling down during a ramp-down

# Contributing
**Thank you for your interest in making the project better and more useful.
Your contributions are highly welcome.**
There are multiple ways of getting involved:
- [Report a bug](#report-a-bug)
- [Suggest a feature](#suggest-a-feature)
- [Contribute code](#contribute-code)
Below are a few guidelines we would like you to follow.
If you need help, please reach out to us by opening an issue.
## Report a bug
Reporting bugs is one of the best ways to contribute. Before creating a bug
report, please check that an [issue](/issues) reporting the same problem does
not already exist. If there is such an issue, you may add your information as a
comment.
To report a new bug you should open an issue that summarizes the bug and set
the label to "bug".
If you want to provide a fix along with your bug report: That is great! In this
case please send us a pull request as described in section [Contribute
Code](#contribute-code).
## Suggest a feature
To request a new feature you should open an [issue](../../issues/new) and
summarize the desired functionality and its use case. Set the issue label to
"feature".
## Contribute code
This is an outline of what the workflow for code contributions looks like
- Check the list of open [issues](../../issues). Either assign an existing
issue to yourself, or create a new one that you would like work on and
discuss your ideas and use cases.
It is always best to discuss your plans beforehand, to ensure that your
contribution is in line with our goals.
- Fork the repository on GitHub
- Create a topic branch from where you want to base your work. This is usually master.
- Open a new pull request, label it `work in progress` and outline what you will be contributing
- Make commits of logical units.
- Make sure you sign-off on your commits `git commit -s -m "adding X to change Y"`
- Write good commit messages (see below).
- Push your changes to a topic branch in your fork of the repository.
- As you push your changes, update the pull request with new infomation and tasks as you complete them
- Project maintainers might comment on your work as you progress
- When you are done, remove the `work in progess` label and ping the maintainers for a review
- Your pull request must receive a :thumbsup: from two [maintainers](MAINTAINERS)
Thanks for your contributions!
### Commit messages
Your commit messages ideally can answer two questions: what changed and why.
The subject line should feature the “what” and the body of the commit should
describe the “why”.
When creating a pull request, its description should reference the corresponding issue id.
### Sign your work / Developer certificate of origin
All contributions (including pull requests) must agree to the Developer
Certificate of Origin (DCO) version 1.1. This is exactly the same one created
and used by the Linux kernel developers and posted on
http://developercertificate.org/. This is a developer's certification that he
or she has the right to submit the patch for inclusion into the project. Simply
submitting a contribution implies this agreement, however, please include a
"Signed-off-by" tag in every patch (this tag is a conventional way to confirm
that you agree to the DCO) - you can automate this with a [Git
hook](https://stackoverflow.com/questions/15015894/git-add-signed-off-by-line-using-format-signoff-not-working)
```
git commit -s -m "adding X to change Y"
```
**Have fun, and happy hacking!**
