[Fleet] Do not allow to use logstash output with APM integration

[nchaulet]

Description

Related to #104987

The APM integration is not compatible with the logstash output type we should not allow user to use a logstash output with that integration.

Test plan

The following scenarios should be covered:

• It's not possible to add APM to a policy using the default data output if the default data output type is logstash
• It's not possible to add APM to a policy using a logstash output as data output.
• It's not possible to make a logstash output the default data output if an agent policy using the default data output contains APM.

Don't we need to do something similar for policies with a Fleet Server integration policy? cc @mostlyjason

I think Fleet server should be able to run with a policy with a logstash output as we pass the ES output as an argument to Fleet server with --fleet-server-es, ... cc @lykkin

yeah, fleet server doesn't actually get its output information from the usual agent pipeline.

not sure if it's being tracked, but endpoint also doesn't support logstash and should be treated similarly.

@brian-mckinney is working on the implementation for endpoint so it should not be a problem.

Hi @nchaulet
We have revalidated this issue on latest 8.2 Snapshot and the feature is working as expected:

• We are not able to add APM integration when policy is set to Logstash output.
• We are not able to add APM integration when policy is set to Default (Currently Logstash Output).
• When APM integration is added we are not able to set output to Logstash under Policy settings.
• When APM integration is added we are not able to set Logstash output to Default under Add Output Settings.

Build details:
BUILD: 51835
COMMIT: 6fcd2d0

Hence marking this as QA:Validated.
Further we will be creating test content for the same.
Thanks

Hi @nchaulet
We have created 04 testcases for this feature under our Fleet test suite at links:

• Validate it’s not possible to add APM to a policy using the Default data output if the Default data output type is logstash.
• Validate that it's not possible to add APM to a policy using a logstash output as data output.
• Validate that it's not possible to make a logstash output the Default data output if an agent policy using the Default data output contains APM.
• Validate that it's not possible to set output to Logstash under Policy settings when APM integration is added.

Please let us know if we are missing anything
Thanks!
