I have a doubt about "AppendLimit". Is this property to limit MAX object numbers of "Metrics" / "MetricProperties" when create a MetricReportDefintion. Please enlighten me, thank you.
"description": "The maximum number of entries that can be appended to a metric report. When the metric report reaches its limit, its behavior is dictated by the ReportUpdates property.",
"longDescription": "This property shall contain a number that indicates the maximum number of entries that can be appended to a metric report. When the metric report reaches its limit, its behavior shall be dictated by the ReportUpdates property. This property shall be required if ReportUpdates is either AppendWrapsWhenFull or AppendStopsWhenFull.",
This property is used to convey the maximum number of entries in a metric report (not the number of metrics the service supports); you can think of it as the maximum array size of "MetricValues" in the "MetricReport" resource. This is used to show when a report will reach its limit, and it could start losing historic samples, or stop reporting entirely.
