NANOG data analysis fuzzy matching

notes

• Analysis of Presentations - Google Sheets this is the original data set (aka raw speaker data or RSD).

  i did some refactoring of this to generate nanog-merge - Google Sheets renamed a number of the fields and done some light refactoring. (RAW tab)

demystifying the placement of group variables

group_var integration appears be within the order listed below. there does seem to be merging (or at least non-overlapping variable unions). but if there's an overlap in values within the group_vars evaluation order, the first hit seems to be the one that gets applied. in the case of my test variable (ansible_user) whatever's defined in the $playbook-dir/group_vars directory, seems to hold particularly tight. even tighter than specifying the user in the ansible-playbook command. so if you're trying to be clever by overriding something within your local project directory, think again.

getting show commands via gnmi

most/lots of our show commands are json framed (you can check this from the cli by piping the command through |json from the CLI. this is also what we effectively expose via eAPI. this also also accessible via gnmi. you just feed the command in with the origin set to cli. note, the syntax w/gnmic is a little janky, but you get the idea.
