# UmayShop — 12. Monitoring, Logging, and Error Handling

> Translation note: This English machine draft preserves the source example snapshot. Language, publication and verification checklist values inside the example are historical sample content, not the current availability of this prototype. No human language signoff or real system verification is implied.

> **fictional example**: The text below is used to demonstrate how to fill out the template, and is not the actual implementation, permissions, deployment, or approval conclusion of UmayShop. Fictional examples cannot enter verified reference material.

Explain where the problem was discovered, how it was located, who took over, and how recovery was verified.

| Project / Compiled by | UmayShop / Example author role |
| Applicable Version / Environment | Example dataset r1 / fictional test environment |
| Code repository / Collection branch / Full fixed commit SHA | Real snapshot not obtained; fictional examples do not fill in fake fixed commit SHAs |
| Most recent confirmation time / Confirmation basis | Unconfirmed / Confirmation record not obtained |
| Access classification | internal: Internal; increase classification when restricted information is involved, inheriting source permissions |

<a id="适用范围与核验结论"></a>

## Scope of Application and Verification Conclusion

| Item | Conclusion |
| --- | --- |
| Coverage | Explain where issues are found, how they are located, who takes over, and how recovery is verified. |
| Collection exclusions | umay/cis-mep and all its subtrees are not collected, not translated, not exported, and not counted toward acceptance |
| Verified Scope | Provides fictional example entries only, private code unverified |
| Number of verified reference materials | 0; this document did not perform real Issue/source code verification |
| Evidence credibility level | Actual system conclusions: low/unknown; confirmed requirement scope: high (single user source, not code proof) |
| Limitations / Gaps | Need to supplement final decision, confirmed permissions, exact SHA, implementation location, and verification records; do not extend front-end static checks into back-end or production conclusions |


<a id="监控对象与指标"></a>

## Monitored Objects and Metrics

> Filling instructions: Record only configured or explicitly to-be-configured metrics. SLO is an internal service quality objective and does not equal actually achieved.

| Object | Metric and unit | Collection location | Threshold / SLO | Current status | Content owner |
| --- | --- | --- | --- | --- | --- |
| API-DEMO | Error rate, response latency ms | Example application metrics | Pending actual test approval | Real monitoring not configured | Example backend role |
| Collection task | Delay minutes, failure count | Example task record | Pending approval | Example | Example documentation role |
| Translation / Export | Source revision lagging, missing diagram count | Example resource validation | Incomplete results must not be marked as successful | Example rule | Example documentation role |


<a id="日志位置与字段"></a>

## Log Locations and Fields

> Instructions: traceId is the identifier that correlates a single invocation. Recording tokens, personal plaintext, and full request bodies is prohibited.

| Log | Location Reference | Required Fields | Prohibited Fields | Retention Period | Access Roles |
| --- | --- | --- | --- | --- | --- |
| Request error | EXAMPLE-LOG-STORE | traceId, service, code, duration, occurredAt | Authorization, personal plaintext | Pending approval | Example maintainer |
| Job audit | EXAMPLE-JOB-LOG | runId, sourceRevision, stage, result | Credentials, private body | Pending approval | Example operations role |


<a id="告警路由与责任"></a>

## Alert Routing and Responsibilities

> Completion notes: Must be able to identify on-duty role, confirmation, and escalation path from each alert; do not enter real personal contact information.

| Alert | Trigger Condition | Notification Role | Acknowledgment Deadline | Escalation Condition | Deduplication / Resolution |
| --- | --- | --- | --- | --- | --- |
| API dependency timeout | Reaches approved threshold | Example backend on-call | Pending approval | Persistent failure | Aggregate by service + error code; clear upon recovery |
| Missing images in export | Resource validation failed | Example documentation maintainer | Pending approval | Retry failed on the same revision | Re-verify after fixing resources |


<a id="故障定位步骤"></a>

## Troubleshooting Steps

> Instructions: Provide an actionable troubleshooting sequence rather than a single sentence like "check logs".

| Step | Check | Read Evidence | Judgment | Next Steps |
| --- | --- | --- | --- | --- |
| 1 | Determine impact scope and start time | runId / traceId / environment | Affects only a specific language or the entire document | Locate corresponding stage |
| 2 | Check fixed commit SHA / source revision | SHA, revisionId | Whether an old snapshot was mixed in | Re-read fixed version |
| 3 | Check dependencies and error types | Desensitized error, timeout record | Retryable or requires manual intervention | Handle according to next section |
| 4 | Verify recovery rather than just restarting | Test results of identical scenario | Successful and without omissions | Record reason and closing time |


<a id="重试-补偿与人工接管"></a>

## Retry, Compensation, and Manual Takeover

> Fill-in instructions: Backoff is delayed retry after failure; unknown upper limits must be clearly specified, without defaulting to an infinite loop.

| Error | Automatic retry | Compensation | Manual takeover conditions | Recovery verification |
| --- | --- | --- | --- | --- |
| Read-only temporary timeout | Example: 1 retry, interval pending approval | Do not write business state | Still fails or cannot be determined | Same query returns valid result |
| Write operation result unknown | First query the original operation result | Confirm by idempotency key, do not repeatedly deduct inventory | Cannot confirm original result | Original record is consistent with current result |
| Authentication failure | Do not retry continuously | None | Update credentials via secure portal | Read-only verification passed and no credentials leaked |


<a id="故障记录与复盘"></a>

## Incident Records and Post-Mortem

> Filling instructions: Completion of handling requires independent verification; retain reason, impact, recovery, and improvement responsibility.

| Incident ID | Impact | Root Cause Evidence | Recovery Action | Verification | Improvement Item |
| --- | --- | --- | --- | --- | --- |
| INC-EX-01 | Example Russian export did not produce files | Simulated record of non-existent image resource | Restore resources and re-verify | EXAMPLE-TEST-12 (example) | Risk R-EX-02 |


<a id="来源-最终决策与代码核验"></a>

## Sources, Final Decisions, and Code Verification

**Inclusion rules**: First confirm "what the final decision is", then verify "what the target version actually did". Issue closure, the latest comment, title, or "resolved" are not sufficient to pass. Same period only indicates candidate association, not that it has been implemented.

| Evidence ID | Source Type / Location | Read Snapshot / Time | Independence and Completeness | Current Status |
| --- | --- | --- | --- | --- |
| EXAMPLE-E12 | Fictional requirements description + fictional code clues | No real snapshot | Reposts from the same source do not count as independent sources; missing attachments must be marked | example_only |

| Decision ID | Issue / Comment ID / Time | Final decision and scope of application | Confirmer and permission basis | Alternative / Conflict Record | Decision Status |
| --- | --- | --- | --- | --- | --- |
| EXAMPLE-D12 | EXAMPLE-ISSUE / EXAMPLE-NOTE / fictional point in time | Displays unknown delivery state, does not presume delivered (fictional example) | Authentic authorized confirmation record not obtained | Authentic conflict unknown | unresolved |

| Final decision ID | Repository / Branch / fixed commit SHA | Implementation file:line number / symbol | Test or verification method / result | Code status / scope | Verifier / Time | Discrepancies and formal introduction conclusion |
| --- | --- | --- | --- | --- | --- | --- |
| EXAMPLE-D12 | Not obtained; do not use fake SHA | Actual implementation location not obtained | Actual verification not performed | unverified / None | Unverified / Unconfirmed | Must not be introduced; re-review after supplementing evidence |

Decision status: `unresolved` (undecided), `confirmed` (validly confirmed), `superseded` (superseded). Code status: `unverified` (unverified), `partial` (partial only), `code_verified` (supported by fixed-version code), `runtime_verified` (tested and supported in target environment). **Static code support does not equal passing production execution.**

The following must be satisfied simultaneously: the final decision has been validly confirmed, there are no unresolved conflicts, relevant code coverage is complete, evidence is locatable, and manual verification records are complete, before it can be listed as verified reference material within its verified scope. Assertions involving deployment, permissions, or the real behavior of external services additionally require operational evidence from the corresponding environment. Historical decisions are retained as history and do not impersonate current rules.

| Gap ID | Missing evidence | Impact | Supplemental Owner / Deadline | Resolution Conditions |
| --- | --- | --- | --- | --- |
| GAP-12-01 | Real decision and code snapshot | Cannot generate verified business conclusions | Pending assignment / Pending confirmation | Complete and record verifier, time, scope, and result |


<a id="附件与图片资源"></a>

## Attachments and Image Resources

| Resource ID | Source / Ownership | Local Relative Path | Integrity / Read Status | Permission Boundary | Language Processing |
| --- | --- | --- | --- | --- | --- |
| Sample Attachment | Original attachment not provided | Not acquired | Not read, not included in verification | Inherits Issue and attachment access scope | Translations and resources not generated |

Attachments must record the original file URL, file name, content checksum, read time, and access classification; access tokens or signed temporary URLs must not be saved. That a link can be opened does not mean the body has been read. Redirection to a login page, corruption, encryption, or unrecognized scans are all marked as unread. Converted text must link to original documents and images, without overwriting the originals.


<a id="人工维护区"></a>

## Manual Maintenance Area

<!-- MANUAL:START -->
To be filled: explanations, exceptions, and operational notes confirmed by the person in charge. Subsequent automatic updates must preserve this section; submit diffs when conflicting with new evidence, and do not silently delete. This initialization script will not update existing content.
<!-- MANUAL:END -->


<a id="语言与下载检查"></a>

## Language and Download Checks

| Check Item | Current Status / Requirement |
| --- | --- |
| Chinese source | This page is in Chinese; source revision fixed by revision_id |
| English / Russian | Not generated. Subsequent automated translations bind to Chinese source revision (source_revision_id); after the source text is updated, old translations are marked as stale |
| Content structure | Translation preserves heading hierarchy, table of contents, tables, code, links, fields, and numerical values; terminology follows the project glossary |
| Images and In-Image Text | Original images and local assets are retained; Chinese text inside images must be separately remade or provided with translation notes; untranslated images are not counted as complete translations |
| Markdown download | When images are included, download as a ZIP containing Markdown + assets + resource manifest; must not provide only invalid remote links |
| PDF Download | Platform must implement pagination, table of contents/bookmarks, tables, Chinese/English/Russian fonts, and local image embedding; missing images should block complete success |
| Export and permissions | Bind document revision, language, image version, and template version; inherit source permissions and do not disclose restricted content |
| Package capability boundary | Only generates Markdown document tree and local diagram source/SVG; does not perform translation, PDF rendering, login, or platform publishing |
