(N.B. I also fix a metric that I forgot to rename in #13540)

Any way to check if we've missed any others? I guess grep for "synapse_.*:.*"?

Should have thought of that; suppose I never really twigged that they all have a convenient synapse_ prefix that makes them greppable instead of 'string with colon' in :-)

Found another pair of sneaky ones ...

I'm just guessing here!!

Could also grep for something like Counter\(\n?.*".*: and Gauge\(\n?.*".*: if you can get the multiline regex stuff working

Conventionally we definitely are meant to use an easily-recognised prefix like synapse_. I don't think even we would ignore that...
