docs: // Gauge - Gauges are a constant data type. They are not subject to averaging,
  // and they don’t change unless you change them. That is, once you set a gauge value,
  // it will be a flat line on the graph until you change it again. If you specify
  // delta to be true, that specifies that the gauge should be updated, not set. Due to the
  // underlying protocol, you can't explicitly set a gauge to a negative number without
  // first setting it to zero.
