Default data collection schedules

Storage Collector agents have a default schedule for topology and performance collections, as described in the following table.

3 hours

n/a

15 minutes

Defines the collection interval for an agent that monitors a storage device using SMI­-S or Hitachi AMS. The management hosts from which the Storage Collector agent collects performance data using SMI-S obtain performance data from the arrays every 15 minutes. Setting the agent to collect data more frequently is inefficient, because the same data is re-collected and discarded.

10 minutes

Defines the collection interval for an agent that uses a different method (than those listed above) to monitor a storage device.

For information about the technologies used by Storage Collector agents to monitor the different kinds of storage devices, see “Configuring Agents to Monitor Storage Devices” in the Foglight for Storage Management Installation Guide.

Modifying Data Collection Schedules for Storage Collector Agents

NOTE: You require the Foglight for Storage Management role Administrator to perform tasks that affect agents.

The collection interval can be increased to reduce the collection frequency impact in busy environments. It is not recommended to reduce the performance collection interval to less than five minutes. You can change the schedule for all agents by editing the default schedule, or clone the default schedule to create and select a specific schedule for a Storage Collector agent.
