Scheduled tasks are automated processing tasks that regularly run JavaScript-based scripts.
After metric data is collected from hosts and stored in the database, the data undergoes several processing tasks for maintenance purposes. Platform Analytics automates the data processing by scheduling these processing tasks to run regularly. Each of these tasks calls a Javascript-based script.
You can modify these tasks, reschedule them, and create new scheduled tasks.
The data latency checker scheduled task checks the data latency in the data collected from the data loaders and data transformers. If the data latency is longer than the configured value or interval, the data latency checker sends an email notification.
By default, the data latency checker scheduled task runs every hour. If you want to modify the default configuration, edit ANALYTICS_TOP/conf/health_check_notify.properties and then restart the Platform Analytics server.
The data purger scheduled tasks, which all have "PartitionMaintenanceGroup" in their names, control the data purger.
For more information, see Data purger.
The duplicate record remover scheduler task checks the most recent data in the database (one to three days old) and deletes any duplicate records in the database (that is, those with a primary key violation). This scheduled task is necessary because the Vertica database does not automatically delete records with a primary key violation.
By default, the duplicate record remover scheduled task runs every 12 hours.
The tablespace partition scheduled tasks maintain partitioned tablespaces by creating new tablespaces or deleting tablespaces that are out of date. The RawTablePartition scheduled task maintains raw tablespace partitions and runs at 4:00 a.m. every day by default, while the ReportTablePartition scheduled task maintains aggregated tablespace partitions runs at 5:00 a.m. every day.
The TSMonitor scheduled task notifies you if any tablespaces have a utilization that exceeds a specified threshold. If you do not increase the tablespace size (or the tablespace does not increase in size automatically), the scheduled task sends a notification every hour. This scheduled task is disabled by default.
This scheduled task has the following prerequisites:
To monitor the tablespaces, the Platform Analytics user on the Oracle database must have the appropriate privileges in the tablespaces (by selecting the privileges on the DBA_DATA_FILES and DBA_FREE_SPACE tables).
Email notification must be enabled to receive the scheduled task notifications. See the Email notification chapter for more details.
