To create a manual outage or to import outage and metric data without affecting the element’s state in Operations Center, consider the following strategies:
Import the metric data with all alarm severities set to OK. Calculations are not affected if all severities are set to OK.
Use the element’s condition algorithm to set its condition to OK. After the import or manual update is complete, change the algorithm to its original settings.
When historical metric data is fed to Operations Center using either strategy, SLA availability, downtime and outage data based on element condition change data do not accurately reflect the state of a business metric because all condition data display as OK.
