Default data collection schedules

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

Performance Collection for EMC SMI-S and Hitachi AMS only

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.

Performance Collection for all others

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.

To modify storage collection schedules:
1
On the navigation panel, under Dashboards, click Administration > Agents.

Click Edit > Edit Properties.
The Agent Status view displays.
5
Select Modify the properties for this agent only.

Scroll down to the Data Collection Scheduler section.
From here you can perform the following agent editing tasks:
