There are some static analyzer metrics as well as metrics you can obtain yourself. These metrics relate to the cost of maintaining code:

- cyclomatic complexity

- statement length, function length

- number of singletons / global instances

- dead code

- duplicated code (intelliJ has a good duplicate detector that anonymizes variables and ignores whitespace and comments).

- number of known functions/types per file (coupling)

- number of commits per file (git-effort from git-extras)

Some of them are tricky to obtain. Making a simple script that parses import statements and outputs a DOT file with a digraph is useful to map dependencies, which is good to explain coupling.
