Description

fixes #3727

Hey @mowies I have started creating custom KeptnMetricsProvider for Elastic and now I have integrated some methods.

For now the methods purpose are-

  • NewElasticProvider: Creates a new KeptnElasticProvider with an Elasticsearch client.
  • FetchAnalysisValue: Runs a query to get analysis results and returns the metric value.
  • EvaluateQuery: Runs a metric query for the last 30 minutes and returns the metric value.
  • runElasticQuery: Executes a query on Elasticsearch and returns the result.
  • extractMetric: Gets the metric value from the Elasticsearch result.

Thank you for the initial version! Can you please provide some tests?

ctx, cancel := context.WithTimeout(ctx, 20*time.Second)
defer cancel()

result, err := r.runElasticQuery(ctx, metric.Spec.Query, time.Now().Add(-30*time.Minute), time.Now())

does the response have a standardized format? maybe we can create a struct and unmarshall to it

does elastic have a mock library? if yes, let's try to use it for testing. if not, maybe we can create an interface and try to mock the elastic to improve the testing, WDYT?

Thanks for the contributions, please see the additional comments on the code. One question tho, did you manually tried the implementation with Keptn? Seems to me that currently won't work, as the new provider is not present in the list of supported providers. If possible please add it and try it out manually.

Also additional question, would it be possible to create a full e2e test for the provider? Would be awesome if we could be able to test it as part of our CI

What I mean is using the elastic metric provider with Keptn, this means setting up an application, monitor it and fetch some data with the elastic metrics provider, used the data for Evaluations and then use Keptn to deploy the application.

The thing is I am not familiar with elk much so can it be like once pr is merged then users who use elk can use it?

I am familiar with code part implementation and till now I feel the provider is mostly correct and the test cases also just a minor change required.

I understand, but part of the implementation should be a e2e/integration test, which will require to deploy the provider and test the correct functioning of the provider with Keptn. In this case I would suggest getting in contact with the author of the issue regarding some more guidance about deploying and using the provider. Therefore we can verify the correct functionality of the provider and potentially also add some configurable parameters, that are needed in the provider.

Another option for the e2e test might be to use mock-server for mocking the responses of the provider, like it's done here. Therefore there is no need for you to actually deploy the provider locally. Please have a look at this option.

In that case, we can maybe ask the author of the issue @arkaonline to test the implementation for us once it's ready and merged before actually releasing the feature. But the e2e test mocking the provider is still needed and the PR shouldn't be merged without it.

Okay so let me go through these and first create the e2e test mocking feature. Also yes the issue author can help us to test the full provider.

@Bharadwajshivam28 @odubajDT I can surely help you test it out.
Please share with me the ELK provider files that needs to be added and the steps I need to add them.
Also , I believe "Elastic" has to be added as supported provider name in helmchart . is that right ?

First, the implementation needs to be finished and covered by unit tests, afterwards we should aim for a integration/e2e test with using the mock server. When this is finished, we can ask @arkaonline to test Keptn with the new provider and afterwards we can proceed with merging the PR.

You should use chainsaw and mock-server how it's done for example here

I am working on this and will finish the logic and unit tests by today and for the e2e tests I will make it finish in upcoming 1-2 days.

The provider is completed and the unit test also I need to just work on the e2e tests

where is this code actually used? Currently it isn't used anywhere, therefore it has no impact on the functionality (dead code). Please add the appropiate changes in the providers factory and also in the KeptnMetricsProvider CRD
