•
Sample Resolution – Specifies how often operational metrics are sampled for a given report:
•
Daily – Sampling is performed once a day.
•
Hourly – Sampling is performed on an hourly basis.
•
Hi Resolution – Sampling is performed at much more frequent intervals as defined by the
"Requested High-Res sampling interval in minutes" option defined through the Sampling Policies
setting which offers the finest granularity of operational statistics.
The retention period for the sampled data in the database tables is set through the sampling policy
(see
“Configuring Sampling Policies” (page 113) ). The data is purged based on the limit set through
the policy settings. You also have the ability to set the data retention period for individual systems
(see
“Adding Storage Systems” (page 46) for details).
•
System and Domain Selection – Specifies the systems and domains that are to be included in
the report.
•
Scope of Report Selection – The options for all reports (except for the Summary report), are
divided into four sections:
◦ Versus Time reports plot data over a period of time (time is along the X-axis). These reports
can either plot aggregate metrics or separate metrics for up to 16 objects. If you want to
compare more than 16 objects, or do more complex object selection you must use the
At Time reports described below.
◦ At Time reports allow you to compare a large number of objects, defined in more complex
ways, but only at a specific point in time. The objects are plotted along the X-axis.
◦
Histogram At Time reports show the distribution of service times and IO sizes at a specific
point in time.
◦ Histogram vs Time reports show the distribution of service times and IO sizes over a
period of time (time is along the X-axis).
•
Time Selection – Selects the time or range of times when the report is to be generated.
•
Object Selection – Selects the list of objects that are to be included in the reporting data. For
example, you can select the VVs, ports and hosts for a VLUN.
•
Format Selection – Selects the format of the report including whether the report should show
charts and/or tables and the type and size of charts.
