Create a Post-Mortem Report

Once an incident has been closed, you can begin the post-mortem process.
1

Select an Incident

From the incident list or incident detail page, select the incident you want to review.
2

Choose a Template

Pick a post-mortem template to define the report’s section structure. The system provides built-in templates in Chinese and English, or you can choose a custom template created by your team.
3

Create with One Click

Click “Create Post-Mortem Report” and the system will automatically extract severity, response time, responders, and other key information from the incident, generate a draft report, and take you to the editor.
Currently, each incident can only have one post-mortem report. If the incident already has a report, the system will open the existing one.

​
Online Collaborative Editing

Once you open the report, you’ll enter an online collaborative editor. If you’ve used Google Docs, Notion, or Feishu Docs before, this will feel very familiar — multiple team members can edit the same report simultaneously, with all changes visible in real time. The editor auto-saves your work, so there’s no need to manually click save.

​
Inserting Images

While editing, you can paste or drag images directly into the editor — monitoring dashboard screenshots, architecture diagrams, or any other key visuals.

​
Refining Report Details

Beyond the report body, there are a few other important fields to pay attention to:

​
Title

The system auto-generates a default title based on the linked incident’s title. You can edit it directly at the top of the editor to something more precise, such as “2026-03-15 Payment Service Timeout Causing Order Failures”. The maximum title length is 256 characters.

​
Key Metrics

The key metrics panel shows the critical indicators for this incident. You can adjust them based on the actual situation:
FieldDescription
Highest severityThe peak severity level of this incident
Earliest start timeWhen the incident was first triggered
Latest close timeWhen the incident was last closed
Total durationThe combined duration of all linked incidents
RespondersPeople who participated in handling the incident

​
Follow-Up Items

Follow-up items are for recording action items that come out of the review — things like “optimize database connection pool settings” or “add cache circuit breaker”. Follow-ups can be edited at any time, whether the report is in draft or published status.

​
Publishing and Managing

​
Publish a Report

Once the team has confirmed the content, click the “Publish” button to switch the report from draft to published.
Publishing isn’t the end of the road. If new findings emerge or corrections are needed later, just switch back to draft, make your changes, and republish.

​
Finding Reports

In the post-mortem report list, you can filter by status, team, channel, and creation date range, with sorting by creation time or last updated time.

​
Deleting a Report

If a report is truly no longer needed, you can delete it from the report detail page.
Deletion is irreversible. Please proceed with caution.
