Monitor storage spaces

When a storage space or partition becomes full, a message is shown in the online message log file.

You can configure alarms that are triggered when storage spaces become full with the STORAGE_FULL_ALARM configuration parameter. You can specify how often alarms are sent and the minimum severity level of alarms to be sent. By default, the alarm interval is 600 seconds and the alarm severity level is 3. For more information about the STORAGE_FULL_ALARM configuration parameters and event alarms, see the Informix® Administrator's Reference.

If the primary server in a high-availability cluster encounters an out-of-space condition, and the STORAGE_FULL_ALARM configuration parameter is enabled, the event alarm is triggered and an error status is returned on the primary server but not on any of the secondary servers. This is expected behavior because log records are no longer sent from the primary server to the secondary servers when the primary server encounters an out-of-space condition. In this case, the secondary servers never exceed their storage limits and thus do not trigger an event alarm or return an error status.

You can use the HCL Informix® Scheduler to set up a task that automatically monitors the status of storage spaces. The properties of the task define the information that Scheduler collects and specifies how frequently the task runs. For example, you might define a task to monitor storage spaces every hour, five days a week. For more information, see The Scheduler and Creating a task.
