Status: RESOLVED FIXED

---

The labelled counters documentation has a section under Recording API for limits. That section states:

• Only increments;
• Saturates at the largest value that can be represented as a 32-bit signed integer.

Further down the page (past the testing API, and into the metrics parameters) under the label section, you get:

• Conform to the label formatting regular expression.
• Each label must have a maximum of 60 bytes, when encoded as UTF-8.
• This list itself is limited to 100 labels.

I feel at least the limit of the number of labels should be included in the limits section at the top of the page - since that is an important limit for this being a labelled counter.
