You can specify the following options.

Options Description Type Required
source_index The name of the detector. string Yes
target_index Specify the target index that the rolled up data is ingested into. You could either create a new target index or use an existing index. The target index cannot be a combination of raw and rolled up data. string Yes
schedule Schedule of the index rollup job which can be an interval or a cron expression. object Yes
schedule.interval Specify the frequency of execution of the rollup job. object No
schedule.interval.start_time Start time of the interval. timestamp Yes
schedule.interval.period Define the interval period. string Yes
schedule.interval.unit Specify the time unit of the interval. string Yes
schedule.interval.cron Optionally, specify a cron expression to define therollup frequency. list No
schedule.interval.cron.expression Specify a Unix cron expression. string Yes
schedule.interval.cron.timezone Specify timezones as defined by the IANA Time Zone Database. Defaults to UTC. string No
description Optionally, describe the rollup job. string No
enabled When true, the index rollup job is scheduled. Default is true. boolean Yes
continuous Specify whether or not the index rollup job continuously rolls up data forever or just executes over the current data set once and stops. Default is false. boolean Yes
error_notification Set up a Mustache message template sent for error notifications. For example, if an index rollup job fails, the system sends a message to a Slack channel. object No
page_size Specify the number of buckets to paginate through at a time while rolling up. number Yes
delay Specify time value to delay execution of the index rollup job. time_unit No
dimensions Specify aggregations to create dimensions for the roll up time window. object Yes
dimensions.date_histogram Specify either fixed_interval or calendar_interval, but not both. Either one limits what you can query in the target index. object No
dimensions.date_histogram.fixed_interval Specify the fixed interval for aggregations in milliseconds, seconds, minutes, hours, or days. string No
dimensions.date_histogram.calendar_interval Specify the calendar interval for aggregations in minutes, hours, days, weeks, months, quarters, or years. string No
dimensions.date_histogram.field Specify the date field used in date histogram aggregation. string No
dimensions.date_histogram.timezone Specify the timezones as defined by the IANA Time Zone Database. The default is UTC. string No
dimensions.terms Specify the term aggregations that you want to roll up. object No
dimensions.terms.fields Specify terms aggregation for compatible fields. object No
dimensions.histogram Specify the histogram aggregations that you want to roll up. object No
dimensions.histogram.field Add a field for histogram aggregations. string Yes
dimensions.histogram.interval Specify the histogram aggregation interval for the field. long Yes
dimensions.metrics Specify a list of objects that represent the fields and metrics that you want to calculate. nested object No
dimensions.metrics.field Specify the field that you want to perform metric aggregations on. string No
dimensions.metrics.field.metrics Specify the metric aggregations you want to calculate for the field. multiple strings No
