# Native histogram notation:
# Native histograms can be used instead of floating point numbers using the following notation:
# {{schema:1 sum:-0.3 count:3.1 z_bucket:7.1 z_bucket_w:0.05 buckets:[5.1 10 7] offset:-3 n_buckets:[4.1 5] n_offset:-5}}

# Native histograms support the same expanding notation as floating point numbers, i.e. 'axn', 'a+bxn' and 'a-bxn'.
# All properties are optional and default to 0. The order is not important. The following properties are supported:

# The counter reset hint associated with this histogram. Defaults to 'unknown' if not set.
