Table 68 recentsample_1 Table
Comment Type Column
The sample resolution, one of hires, hourly or daily. VARCHAR(32) NOT NULL resolution
Sample time in secs of the most recent complete sample of the
resolution. This is the Unix time and is the number of seconds since
0:00:00 Jan 1, 1970 GMT. INTEGER NOT NULL tsecs
The Sample Data and Inventory Tables
The sample data tables include the space and performance samples of various objects in the
systems. For each type of sample, there are three separate tables, one for each sampling resolution:
•
hires - High resolution samples
•
hourly - Hourly samples
•
daily - Daily sample.
The tables for the different resolutions are identical in their structure. In the table names, the substring
<res> can be replaced by either hires, hourly or daily.
The database often needs to be queried to determine all the objects that are present in the table.
Often, this information is used to populate the menus in a web browser or Excel client. Since the
data tables can be very large, this type of query can take a long time in spite of indexes on the
data tables. To improve the efficiency of these queries, a separate set of inventory tables is
maintained, one for each sample data table. The inventory tables contain a row for each distinct
object in the corresponding sample data table. When the sampler inserts new samples into a table,
or removes older samples from a table, it also updates the corresponding inventory table.
The pdspace Table
The pdspace_<res>_3 table holds physical disk (PD) space data samples.
