Postmortems

Postmortems are reports that allow users to learn from major incidents by providing a summary of events that transpired, how the response was handled, and what resolution steps were taken. Postmortems curate a timeline of activity in PagerDuty and Slack, which teams can analyze to determine follow-up actions for similar situations in the future and, ideally, help prevent them altogether.

Slack Data Source

To include Slack content in a postmortem, a contributor must authorize PagerDuty to access Slack on their behalf, which will let that contributor see Slack content in the Available Data listing. Each PagerDuty user will need to authorize with Slack individually.

If your Slack user account does not have permissions to add apps to your team, you will need to first ask a Slack admin to go to Slack's App Directory and authorize the PagerDuty Postmortems app.

Click Save Data Sources to continue.

  1. Timeline: All Slack messages and incident log entries from the above data sources will be listed in the Available Data (left) slush bucket. The incident Trigger and Resolve log entries will be listed in the Included in Timeline (right) slush bucket by default.
  • To add Slack messages or incident log entries to the timeline: Select the event and click the button, or click the to the left of the event to move it from the left to the right slush bucket. You can add multiple items at once by selecting them while holding the shift key and then using the button to move them to the timeline. You can also manually add freeform entries to your timeline by selecting New Timeline Entry. Any Slack entries that are moved from the Available Data listing into the postmortem's Timeline will be visible to anyone looking at the postmortem.
  • To remove an event from the timeline: Select the event and click the button, or click the to the left of the event to move it to the left slush bucket.
