[!WARNING]

Rate limit exceeded

@illia-malachyn has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 18 minutes and 37 seconds before requesting another review.

How to resolve this issue? After the wait time has elapsed, a review can be triggered using the `@coderabbitai review` command as a PR comment. Alternatively, push new commits to this PR. We recommend that you space out your commits to avoid hitting the rate limit.
How do rate limits work? CodeRabbit enforces hourly rate limits for each developer per organization. Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout. Please see our [FAQ](https://coderabbit.ai/docs/faq) for further information.

Walkthrough

The recent updates significantly improve the application's monitoring capabilities by introducing the StorageSizeCollector for tracking disk usage metrics. A new configurable update interval provides flexibility for real-time storage metric collection, enhancing both observability and performance. These changes ensure clearer insights into storage utilization and simplify the metric registration process, ultimately enriching the application's operational oversight.

Changes

Files Change Summary
bootstrap/bootstrap.go, config/config.go, metrics/storage_collector.go Enhanced monitoring by initializing a storageSizeCollector with a configurable update interval for real-time tracking.
metrics/collector.go Simplified metric registration by removing the logger parameter from NewCollector and using promauto for automatic Prometheus registration.
services/traces/engine_test.go Updated tests to instantiate Collector with NewNoopCollector(), removing the logging dependency, streamlining the test environment.

Poem

🐇 In the meadow, metrics bloom,
A storage watcher clears the gloom.
With intervals set, we gather more,
Digging deep, we explore the core.
Hop along, let data flow,
In our fields, new insights grow! 🌼

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 .` - `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 generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@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 as 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. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### 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](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
