Poem

In the fields of code, we hop and play,
New metrics bloom, brightening the day.
With tags that soar, our versions align,
OpenTelemetry shines, oh how divine!
Configs refined, like a rabbit's dance,
In Kubernetes gardens, we take our chance! 🐇✨

`201-203`: **Excellent addition of new node conditions and metrics!** The inclusion of `DiskPressure`, `PIDPressure`, and `NetworkUnavailable` node conditions, along with the `k8s.node.condition` and `k8s.pod.status_reason` metrics, significantly enhances the cluster's observability. These additions will provide more comprehensive insights into the cluster's health and potential issues. Also applies to: 209-213 --- Line range hint `1-924`: **Summary of changes and their impact** This update brings two main improvements to the Kubernetes infrastructure setup: 1. Enhanced cluster metrics: New node conditions and metrics have been added, which will provide more detailed insights into the cluster's health and performance. 2. OpenTelemetry Collector version update: Both OtelAgent and OtelDeployment have been updated to version 0.109.0, which likely includes new features, bug fixes, and performance improvements. These changes should significantly improve the observability of your Kubernetes cluster. However, ensure that you've thoroughly tested the new version and reviewed any potential breaking changes before deploying to production. --- Line range hint `277-277`: **Approved: OpenTelemetry Collector version update** The update of the OpenTelemetry Collector image from version 0.88.0 to 0.109.0 for both OtelAgent and OtelDeployment is a significant upgrade. This likely brings important improvements and new features. Please ensure that: 1. This version is compatible with your current setup. 2. You've reviewed the changelog for any breaking changes or new features that may require configuration updates. 3. You've tested this version in a non-production environment before deploying to production. To assist with the verification, you can run the following script to check for any potential issues: Also applies to: 574-574
✅ Verification successful **** The OpenTelemetry Collector image has been successfully updated from version **0.88.0** to **0.109.0** in `charts/k8s-infra/values.yaml`. No remaining hardcoded references to the old version were found in the codebase. Please proceed with testing to ensure full compatibility and verify that all functionalities operate as expected.
🏁 Scripts executed The following scripts were executed for the analysis: Script: ```shell #!/bin/bash # Description: Check for potential compatibility issues with the new OpenTelemetry Collector version # Test: Search for custom configurations that might be affected by the version update echo "Searching for custom OpenTelemetry Collector configurations:" rg --type yaml 'otelcol|opentelemetry' -g '!charts/k8s-infra/values.yaml' # Test: Check if there are any hardcoded version references that need updating echo "Checking for hardcoded OpenTelemetry Collector version references:" rg --type yaml '0\.88\.0' -g '!charts/k8s-infra/values.yaml' echo "Please review these results and ensure all necessary updates have been made." ``` Length of output: 2259

`165-166`: **Ensure the 'metrics' field under 'k8s_cluster' receiver is correctly configured** The `metrics` field has been added under the `k8s_cluster` receiver. Please verify that the metrics specified in `.Values.presets.clusterMetrics.metrics` align with the expected configuration schema of the `k8s_cluster` receiver in the OpenTelemetry Collector. This ensures that only valid and supported metrics are collected without causing configuration errors.

🪧 Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , please review it.` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
