Reference: Schedule Events

Schedule events are triggered automatically at various intervals per Organization or per Sensor, observable in D&R rules via the schedule target.

Scheduling events have a very similar structure whether they are per-sensor or per-org.

The event component contains a single key, frequency which is the number of seconds frequency this scheduling event is for. The event type also contains the human readable version of the frequency.

The following frequencies are currently emitted:

• 30m: 30m_per_org and 30m_per_sensor

• 1h: 1h_per_org and 1h_per_sensor

• 3h: 3h_per_org and 3h_per_sensor

• 6h: 6h_per_org and 6h_per_sensor

• 12h: 12h_per_org and 12h_per_sensor

• 24h: 24h_per_org and 24h_per_sensor

• 168h (7 days): 168h_per_org and 168h_per_sensor

Scheduling events are generated for each org that meets the following criteria:

• Has had at least 1 sensor online in the last 7 days.

Scheduling events are generated for each sensor that meets the following criteria:

• Has been online at least once in the last 30 days.

Scheduling events are not retained as part of the year retention in LimaCharlie. To leverage them, create D&R rules that target the schedule target and take the relevant action when matched. For example to issue an os_packages once per week on Windows hosts:

detect:
  target: schedule
  event: 168h_per_sensor
  op: is platform
  name: windows
respond:
  - action: task
    command: os_packages
    investigation: weekly-package-list
