33-36: Yo dawg, let's make this error schema more robust!The schema structure is solid, but we could make it even better with some improvements:
Consider applying these enhancements:
const errorSchema = mongoose.Schema({ - metric: { type: [String], default: [] }, - err: { type: String, default: "" }, + affectedMetrics: { type: [String], default: [], required: true }, + errorMessage: { + type: String, + default: "", + required: true, + validate: { + validator: function(v) { + return v.length <= 1000; // Prevent massive error strings + }, + message: 'Error message too long' + } + } });Server/service/statusService.js (2)
105-111: Yo dawg, these changes are fire but let's make them bulletproof! 🔥The defensive programming with optional chaining and nullish coalescing is on point! However, we might want to add some type validation to ensure the extracted data matches our expectations.
Consider adding type checks before assignment:
const { cpu, memory, disk, host } = payload?.data ?? {}; const { errors } = payload; -check.cpu = cpu ?? {}; -check.memory = memory ?? {}; -check.disk = disk ?? {}; -check.host = host ?? {}; +check.cpu = typeof cpu === 'object' ? cpu : {}; +check.memory = typeof memory === 'object' ? memory : {}; +check.disk = typeof disk === 'object' ? disk : {}; +check.host = typeof host === 'object' ? host : {}; check.errors = Array.isArray(errors) ? errors : [];
138-140: Mom's spaghetti moment: Let's add some logging! 🍝The change to build the check before the operation is solid. However, we could enhance observability by adding some debug logging.
Consider adding debug logging:
const check = this.buildCheck(networkResponse); +this.logger.debug({ + service: this.SERVICE_NAME, + method: "insertCheck", + message: "Built check object", + monitorId: check.monitorId, + type: networkResponse.type +}); await operation(check);

57-60: Mom's spaghetti moment: Let's optimize this errors field!
The integration looks clean, but we can make it more performant and maintainable.
Consider these enhancements:
- Add an index for error querying:
HardwareCheckSchema.index({ 'errors.metric': 1 });- Add validation to prevent excessive error entries:
errors: {
type: [errorSchema],
default: () => [],
+ validate: {
+ validator: function(v) {
+ return v.length <= 100; // Prevent error array explosion
+ },
+ message: 'Too many errors recorded'
+ }
},Let's check if there are any existing queries that might benefit from the new index:

105-111: Let's verify these changes match the Monitoring Agent updates! 🎯
The changes align with the PR objectives of updating the hardware check schema and StatusService. However, let's verify the data structure matches the Monitoring Agent's output.
Also applies to: 138-140
✅ Verification successful
The previous search was too specific. Let's broaden our search to find relevant monitoring and hardware-related code structures to verify the changes align with the monitoring agent's output format.
The previous search revealed the code structure in statusService.js, but we need more context around this implementation and any test cases that might validate the expected data structure. Let's dig deeper into the codebase to verify the changes.
Yo, the code's legit! The hardware check structure is on point! 🎯
The changes in statusService.js perfectly match the expected data structure, as confirmed by:
- The implementation properly handles all hardware metrics (cpu, memory, disk, host)
- Test cases validate both successful and fallback scenarios
- Error handling is implemented with proper fallbacks using nullish coalescing
- The structure aligns with the monitoring agent's payload format as shown in the test files
