It sort of depends on how you're building your server availability report. If you're running various splunk searches, you can run the following search against the ITSI summary index:
index=itsi_summary "is_entity_in_maintenance=1" | table entity_title, entity_key, kpi, itsi_service_id
The above will look for all of the entities (in a set period of time) that executed for KPI searches and display the entities, KPIs, and the services those entities are being used with.,You can see if an entity (that is being used by KPIs) is in maintenance by doing a search like the following against the summary index:
index=itsi_summary "is_entity_in_maintenance=1" | table entity_title, entity_key, kpi, itsi_service_id
The above search will return results for KPI searches that executed with the an entity in maintenance. You could potentially use the result over a period of time to get a complete list of all entities that were in maintenance with the service_ids and kpis affected.
