🛠️ Refactor suggestion
Replace console.log with logger utility.
The implementation looks solid, but we should maintain consistent logging practices across the codebase.
Apply this diff to use the logger utility:
- console.log("deleted hardware checks", result);
+ logger.info({
+ message: "Deleted hardware checks",
+ service: SERVICE_NAME,
+ method: "deleteHardwareChecksByMonitorId",
+ details: result
+ });Committable suggestion skipped: line range outside the PR's diff.

💡 Codebase verification
Yo, we've got spaghetti code on our sweater! 🍝
The monitor deletion process isn't calling deleteHardwareChecksByMonitorId when a monitor is deleted. This could leave orphaned hardware check records in the database.
- In
Server/db/mongo/modules/monitorModule.js, thedeleteMonitorfunction needs to calldeleteHardwareChecksByMonitorIdbefore or afterMonitor.findByIdAndDelete(monitorId) - Same applies to
deleteAllMonitorsanddeleteMonitorsByUserIdwhich should clean up associated hardware checks
The hardware check deletion function is properly implemented with error handling, but it's not being used where it should be. Mom's spaghetti would not approve! 🤌
🔗 Analysis chain
Knees weak, arms heavy, but we gotta verify this integration! 🍝
Let's ensure the hardware check deletion is properly integrated with the monitor deletion process.
Please ensure that:
- The monitor deletion process properly calls
deleteHardwareChecksByMonitorId - Error handling follows the established patterns in the codebase
Also applies to: 219-219

2. Detailed Technical Analysis
2.1 Code Logic Deep-Dive
Core Logic Changes
Server/controllers/monitorController.js - deleteMonitor
-
Submitted PR Code:
try { const monitor = await req.db.deleteMonitor(req, res, next); // Delete associated checks, alerts, and notifications try { await req.jobQueue.deleteJob(monitor); await req.db.deleteChecks(monitor._id); await req.db.deletePageSpeedChecksByMonitorId(monitor._id); await req.db.deleteNotificationsByMonitorId(monitor._id); await req.db.deleteHardwareChecksByMonitorId(monitor._id); } catch (error) { logger.error({ message: `Error deleting associated records for monitor ${monitor._id} with name ${monitor.name}`, service: SERVICE_NAME, method: "deleteMonitor", stack: error.stack, }); } return res.status(200).json({ success: true, msg: successMessages.MONITOR_DELETE }); } catch (error) {
-
Analysis:
- Current logic and potential issues:
- The current logic ensures that associated hardware checks are deleted when a monitor is deleted. However, the error handling within the nested try-catch block does not roll back the monitor deletion if any of the associated deletions fail. This can lead to inconsistent states where the monitor is deleted, but some associated data remains.
- Edge cases and error handling:
- If any of the deletion operations (
deleteJob,deleteChecks,deletePageSpeedChecksByMonitorId,deleteNotificationsByMonitorId,deleteHardwareChecksByMonitorId) fail, the monitor deletion should ideally be rolled back to maintain data consistency.
- If any of the deletion operations (
- Cross-component impact:
- This affects the interaction between the
monitorControllerand the database layer, specifically thehardwareCheckModule. Ensuring atomicity in the deletion process is crucial for maintaining data integrity.
- This affects the interaction between the
- Business logic considerations:
- The business logic requires that all associated data be deleted atomically to prevent orphaned records and ensure data consistency.

LlamaPReview Suggested Improvements:
try { const monitor = await req.db.deleteMonitor(req, res, next); // Start a transaction to ensure atomicity const session = await req.db.startSession(); session.startTransaction(); try { await req.jobQueue.deleteJob(monitor); await req.db.deleteChecks(monitor._id); await req.db.deletePageSpeedChecksByMonitorId(monitor._id); await req.db.deleteNotificationsByMonitorId(monitor._id); await req.db.deleteHardwareChecksByMonitorId(monitor._id); await session.commitTransaction(); } catch (error) { await session.abortTransaction(); logger.error({ message: `Error deleting associated records for monitor ${monitor._id} with name ${monitor.name}`, service: SERVICE_NAME, method: "deleteMonitor", stack: error.stack, }); throw error; // Re-throw the error to ensure the monitor deletion is rolled back } finally { session.endSession(); } return res.status(200).json({ success: true, msg: successMessages.MONITOR_DELETE }); } catch (error) {

Improvement rationale:
- Technical benefits:
- Ensures atomicity in the deletion process, preventing partial deletions and maintaining data consistency.
- Business value:
- Enhances data integrity and reliability, ensuring that all associated data is deleted when a monitor is removed.
- Risk assessment:
- Introduces a transaction to manage the deletion process, which adds complexity but significantly reduces the risk of data inconsistency.
