Abstract: A time series database system receives a trigger condition associated with time series data points corresponding to subsystems of the system. The system aggregates the time series data points associated with a first time into a first internal time series data point. The system aggregates the time series data points associated with a second time into a second internal time series data point if the first internal time series data point does not meet the trigger condition. The system calculates a projected internal time series data point based on the first internal time series data point and the second internal time series data point if the second internal time series data point does not meet the trigger condition. The system outputs a projected alert notification associated with the projected internal time series data point and the trigger condition if the projected internal time series data point meets the trigger condition.

Abstract: A self-monitoring time series database system which enforces usage policies is described. A time series database system receives an alert trigger condition for a system user, wherein the system user is associated with multiple time series data points corresponding to multiple subsystems of the time series database system. The time series database system aggregates the multiple time series data points in an internal time series data point, which is internal to the time series database system, associated with the system user. The time series database system evaluates whether the internal time series data point associated with the system user meets the alert trigger condition. The time series database system reduces a level of access by the system user to the time series database system in response to an evaluation that the internal time series data point associated with the system user meets the alert trigger condition.

Abstract: Annotating time series data points with alert information is described. A system retrieves a time series data point and a corresponding alert trigger condition from a time series database. The system evaluates whether the time series data point meets the corresponding alert trigger condition. The system outputs an alert notification associated with the time series data point and the corresponding alert trigger condition if the time series data point meets the corresponding alert trigger condition. The system annotates the time series data point, in the time series database, with alert information associated with the corresponding alert trigger condition if the time series data point meets the corresponding alert trigger condition.
