選択肢
- The list of tools that were used, with the version of each one, so that the same set can be assembled again by whoever handles the next such occurrence.
- The cost of the outage in lost compute hours, expressed against the price of the cluster, so that management can weigh the investigation effort against what the interruption was worth.
- What was observed, what the observation ruled in and out, what was changed, and what will detect it sooner next time.
- A timeline of every action taken during the investigation with the identity of the operator who took each of them, because a report whose purpose is to allow the next occurrence to be handled faster has to record who knew what at each point so that the same people can be involved again in the same order when it happens.
