What Is the Relationship Between the Time Range and Statistical Cycle?

Updated at: Nov 25, 2019 GMT+08:00

For Application Operations Management (AOM), a maximum of 1440 data points can be returned for a single metric query. The relationship between the time range and statistical cycle is as follows:

Maximum time range = Statistical cycle x 1440

If you select a time range shorter than or equal to the maximum time range, all the statistical cycles that meet the preceding formula can be selected. For example, if you want to query metrics in the last 1 hour, the available statistical cycles are 5s, 10s, 30s, 1 minute, and 5 minutes.

When second-level monitoring is started, the time ranges longer than 1 day are automatically removed, and the Last 10 minutes option is added. When second-level monitoring is stopped, the previous time range is used. The following tables list the relationship between the time range and statistical cycle. Table 1 lists their relationship when second-level monitoring is not started, while Table 2 lists their relationship when second-level monitoring is started.
