What is best way to capture query latency?

[chanzlee]

I'm trying to log query latency for service health check but I cannot find the good place to start.

I see onSettled from default query options but there's no callback like onFired to capture the start time.

Should I create a wrapper hook for the queries and capture the start time there?

I would move this to the queryFn:

useQuery('key', async () => {
  captureStartTime()
  const { data } = await axios.get(....)
  captureEndTime()
  return data
})

or even move it to a different layer, like axios interceptors.
