Exclusion periods are time periods which you want to exclude from an XLM report.

For example, scheduled upgrades and maintenance can disrupt performance, so you may not want those periods reflected in XLM reports. Likewise, you may want XLM reports to exclude weekends, holidays, or other times with atypical usage patterns.

XLM queries executed against your Analytics event data observe only the exclusion periods you explicitly configure in the XLM UI. You configure exclusion periods using the time zone of your choice. Under the hood, Splunk AppDynamics keeps track of the exclusion period in the corresponding GMT dates.
