closes: https://github.com/elastic/kibana/issues/166428 ## Summary This PR removes code that is no longer needed after replacing the Node Details View for Host with the Asset Details. ### TSVB The TSVB files were apparently only used to display charts in the Node Details view. Due to the Asset Details using Lens to power the charts, corresponding `host` TSVB formulas and configs are no longer needed. Therefore, `host*`, `hostK8s*`, and `hostDocker*` (the latter appears to have never been used) have been removed. Additionally, `aws*` from `required_metrics` was also removed because it was host-specific. ### FE Components The main change is in the `useMetadata` hook. I have changed the hook signature, making `requiredMetrics` optional. This parameter is used to process additional filtering and is only used in asset types that the old Node Details page supports. Not passing it is not expected to break other places that depend on this hook. ### Server Removing TSVB files has a direct impact on the `api/metrics/node_details` endpoint. This endpoint is only used to provide data to the Node Details page. It returns a 400 error if an invalid metric is passed - which will be the case for hosts **Example Request:** ```json POST kbn:api/metrics/node_details { "metrics": [ "hostK8sCpuCap", "hostSystemOverview" ], "nodeId": "gke-release-oblt-release-oblt-pool-c4163099-bcaj", "nodeType": "host", "timerange": { "from": 1695210522045, "to": 1695214122045, "interval": ">=1m" }, "cloudId": "6106013995483209805", "sourceId": "default" } ``` **Response:** ```json { "statusCode": 400, "error": "Bad Request", "message": "Failed to validate: \n in metrics/0: \"hostK8sCpuCap\" does not match expected type \"podOverview\" | \"podCpuUsage\" | \"podMemoryUsage\" | \"podLogUsage\" | \"podNetworkTraffic\" | \"containerOverview\" | \"containerCpuKernel\" | \"containerCpuUsage\" | \"containerDiskIOOps\" | \"containerDiskIOBytes\" | \"containerMemory\" | \"containerNetworkTraffic\" | \"containerK8sOverview\" | \"containerK8sCpuUsage\" | \"containerK8sMemoryUsage\" | \"nginxHits\" | \"nginxRequestRate\" | \"nginxActiveConnections\" | \"nginxRequestsPerConnection\" | \"awsEC2CpuUtilization\" | \"awsEC2NetworkTraffic\" | \"awsEC2DiskIOBytes\" | \"awsS3TotalRequests\" | \"awsS3NumberOfObjects\" | \"awsS3BucketSize\" | \"awsS3DownloadBytes\" | \"awsS3UploadBytes\" | \"awsRDSCpuTotal\" | \"awsRDSConnections\" | \"awsRDSQueriesExecuted\" | \"awsRDSActiveTransactions\" | \"awsRDSLatency\" | \"awsSQSMessagesVisible\" | \"awsSQSMessagesDelayed\" | \"awsSQSMessagesSent\" | \"awsSQSMessagesEmpty\" | \"awsSQSOldestMessage\" | \"custom\"\n in metrics/1: \"hostSystemOverview\" does not match expected type \"podOverview\" | \"podCpuUsage\" | \"podMemoryUsage\" | \"podLogUsage\" | \"podNetworkTraffic\" | \"containerOverview\" | \"containerCpuKernel\" | \"containerCpuUsage\" | \"containerDiskIOOps\" | \"containerDiskIOBytes\" | \"containerMemory\" | \"containerNetworkTraffic\" | \"containerK8sOverview\" | \"containerK8sCpuUsage\" | \"containerK8sMemoryUsage\" | \"nginxHits\" | \"nginxRequestRate\" | \"nginxActiveConnections\" | \"nginxRequestsPerConnection\" | \"awsEC2CpuUtilization\" | \"awsEC2NetworkTraffic\" | \"awsEC2DiskIOBytes\" | \"awsS3TotalRequests\" | \"awsS3NumberOfObjects\" | \"awsS3BucketSize\" | \"awsS3DownloadBytes\" | \"awsS3UploadBytes\" | \"awsRDSCpuTotal\" | \"awsRDSConnections\" | \"awsRDSQueriesExecuted\" | \"awsRDSActiveTransactions\" | \"awsRDSLatency\" | \"awsSQSMessagesVisible\" | \"awsSQSMessagesDelayed\" | \"awsSQSMessagesSent\" | \"awsSQSMessagesEmpty\" | \"awsSQSOldestMessage\" | \"custom\"" } ``` ### How to Test - Start a local Kibana instance pointing to an oblt cluster. - Navigate to `Infrastructure`. - Try different asset types and navigate to the Node Details view. --------- Co-authored-by: Kibana Machine <42973632+kibanamachine@users.noreply.github.com> |

- Documentation
- Version Compatibility with Elasticsearch
- Questions? Problems? Suggestions?
Getting Started
If you just want to try Kibana out, check out the Elastic Stack Getting Started Page to give it a whirl.
If you're interested in diving a bit deeper and getting a taste of Kibana's capabilities, head over to the Kibana Getting Started Page.
Using a Kibana Release
If you want to use a Kibana release in production, give it a test run, or just play around:
- Download the latest version on the Kibana Download Page.
- Learn more about Kibana's features and capabilities on the Kibana Product Page.
- We also offer a hosted version of Kibana on our Cloud Service.
Building and Running Kibana, and/or Contributing Code
You might want to build Kibana locally to contribute some code, test out the latest features, or try out an open PR:
- CONTRIBUTING.md will help you get Kibana up and running.
- If you would like to contribute code, please follow our STYLEGUIDE.mdx.
- For all other questions, check out the FAQ.md and wiki.
Documentation
Visit Elastic.co for the full Kibana documentation.
For information about building the documentation, see the README in elastic/docs.
Version Compatibility with Elasticsearch
Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.
Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.
| Situation | Example Kibana version | Example ES version | Outcome |
|---|---|---|---|
| Versions are the same. | 7.15.1 | 7.15.1 | 💚 OK |
| ES patch number is newer. | 7.15.0 | 7.15.1 | ⚠️ Logged warning |
| ES minor number is newer. | 7.14.2 | 7.15.0 | ⚠️ Logged warning |
| ES major number is newer. | 7.15.1 | 8.0.0 | 🚫 Fatal error |
| ES patch number is older. | 7.15.1 | 7.15.0 | ⚠️ Logged warning |
| ES minor number is older. | 7.15.1 | 7.14.2 | 🚫 Fatal error |
| ES major number is older. | 8.0.0 | 7.15.1 | 🚫 Fatal error |
