Description:

Fixes #8265.

The only part that wasn't specified in the Spec is what to use as the timestamp of the target info metric. I've chosen to use the most recent timestamp in the batch.

Alternatives:

  • We could set it to time.Now(), but then it would have a different timestamp from the rest of the batch, which might cause some strange behavior.
  • We could also pick a random timestamp from the batch and use that. That would work well in the standard case in which all scraped prometheus metrics have their timestamp set to the scrape time.

Testing:

Added unit tests
