Thanks for the point about Notebooks, we have not thought in detail on how people use that. Is it primarily to collaborate between team members when an incident happens or even when there is no incident, and you are analysing stuff
- Incidents, collecting different metrics and showing them next to each other, with comments
- Longer-term reliability debugging. They can form a kind of ad-hoc dashboard. These are usually issues that degrade performance, don't have immediate or wide-spread customer impact, and are things we are not immediately able to detect
- Related, performance tuning. Sometimes, the key metric is unknown. We want to explore it, and then make changes to infra, and then see if that moved the needle
- Sometimes, the ad-hoc widgets are useful enough to export to a dashboard
- I can take any widget anywhere else and import it into a notebook, or start a new notebook out of it.
The notebooks are similar to the dashboard, just that, the layout engine only allows a linear notebook layout instead of a grid. There are already text widgets, though the button to add that is easier to access. Other than the comments, it's basically a dashboard with the UI changed so that it feels like a notebook.
Keep in mind too, all dashboard and notebooks modify timestamps and other states in the browser URL, so it is easy for me to copy-paste those into Slack so that other people can see what I am seeing.
