System Reporter 2.8

8.4.15.1 value:

<tsecs>

If

<tsecs> is non-negative it represents

a point in time, expressed as the

number of seconds since January 1, 1970, GMT. For example, to express 2005/07/13 11:00:34

as a

<tsecs>

value, use the value

1121277634

.

If <tsecs> is negative, it represents a point in time <tsecs> seconds before the current time.

8.4.15.2 example:

The following example specifies an endrange time of 11:00:34 on July 13, 2005:

8.4.16 groupby

Use the

groupby

option to select what is charted on the category axis

(X-axis). The default for

groupby

is

System

, which means that you will see a bar (when using

a barchart) for each system. The value is the total of the metric for the entire system. The

groupby

option can be used multiple times in the same query string, and when specified

multiple times functions as an

OR

operation. If an object name exists on more than one system

and if

System

is not selected as a

groupby

parameter, the resulting metric for that object will

be the aggregate of the metric across all the selected systems that include the object name.

This can be useful, for example if a host is connected to multiple systems and that host is

assigned the same name on all those systems. In that case, selecting

Host

as the

groupby

parameter will show that hosts total performance across all systems.

8.4.16.1 values:

Specify one of the following:

System

(Default). When using

groupby=System

, you will not be able to see the breakdown of the

metric for individual components (for example, volumes or hosts) in the system.

NOTE: You can use the

sample_times

report (see

sample_times

on page 8.78)

to see

tsecs

values paired with times expressed using an easier-to-read format.
