Specifications

Note: Configuration jobs should not occur more often than once per hour. For all
practical purposes, the default setting of collection once every 12 hours is
sufficient. Sample schedules default to run every 10 minutes and this is fast
enough for most practical applications.
For each collection schedule, you can modify the following information by clicking
Change Schedule:
l Start Time: Indicates the date and time from which to begin the data
collection job.
l Performance Interval: Indicates the time interval on which the job is
performed.
l Enable Schedule: Indicates whether the job is enabled or disabled for data
collection.
Note: For each data source, schedule two jobs to provide configuration,
performance, and state information for virtual machines, a configuration data
collection job and a sample data collection job. This includes VirtualCenters,
unmanaged ESX hosts, and Hyper-V hosts.
After all of the data collection jobs have been scheduled and enabled, the
scheduler executes each job at the specified start time and continues to run them
at the specified interval. The time it takes for a job to complete varies widely
based on the size of the environment to be collected from. To execute a collection
schedule immediately, select the schedule on the Collection Schedules screen,
and then click Run Now.
