You can further customize this, to also include the error message you receive for the flow error. I find this redundant, as I have to access the flow anyways to correct the error, and it will tell me the reason why the error has occurred there.
In the finally scope, I have created a SharePoint list and then I store my variable and the flowname and flowURL.
Now your scopes are all setup, except we need to configure the "run after" settings. So you always want your try scope to run, this is the bread and butter of your flow and where all the magic happens. If your try scope is successful it loads that into the string variable, and you can save the successful flow run in your SharePoint list.
If your try scope encounters an error, we want the catch scope to run, you do that by setting the "configure run after" settings for the catch scope up like this:
So if your try scope fails or times out, the catch scope will run where you set the string variable to "error", you collect the flowname and URL and send an e-mail to whomever is in charge of the flow. Again, the finally scope will run, and the error status is noted into your SharePoint list.
From there, you can create any type of flow that scans your SharePoint list for all the error flows, and notify you if they haven't been fixed. I have set it as default, that when an item is created in my SharePoint list, it gets an "Unsolved" property in a choice column, and once I solve the error I have to manually access the SharePoint list and change the value to "Solved". My flow scans for all "Unsolved" properties, and notifies me if any of them is 24 hours or more old everyday, just to keep myself on my toes.
Hope it makes sense,
