Symptom:
The left side of the Time Series Facility (TSF) chart has level lines.
Solution:
The TSF metric database is tiered so that data becomes less granular the longer it is stored. The records are aggregated when they reach the expiration age that is specified in the metric management settings. If a user request data at a granularity less than available for the time period, the aggregated values are split evenly into the smaller time intervals. When displayed in a chart, the averaged values appear as level lines. To view the chart without averaged values, reset the Period selector to a larger value.
