Sample interval in SolarWinds VNQM
The sample interval dictates the precision of your generated chart. A single point or bar is plotted for each sample interval. If a sample interval spans multiple polls, polled data is automatically summarized and plotted as a single point or bar on the chart.
Due to limits of memory allocation, some combinations of time periods and sample intervals can require too much system resources to display, due to the large number of polled data points. As a result, charts might not be displayed if the time period is too long or if the sample interval is too short.
