Data Caches Spinlocks Tab

This dashboard shows the Spinlocks that occurr for each Data Cache. Use this dashboard for detecting data cache that may suffer a contention and monitor it over time.

The table columns are the same as in Spinlocks table in Spinlocks Tab.

Database Spaces and Trends Dashboard

The Database Spaces and Trends dashboard shows details about databases and table spaces and the overall trends. This dashboard contains the following tabs:

•

•

Table Spaces Tab

•

Table Performance Tab

•

Top I/O Active Tables

•

Top Lock Activity Tables

DB Spaces Tab

Device activity information is provided in a table and a chart:

Table Spaces Tab

The Table Spaces information is provided in a table.

To enable the data collection for a database and to display this data on the Table Spaces tab, the database must be added to the Table Space Monitoring list in the Table Space Management group of the Sybase_MDA Agent properties. For more information, see Setting Table Space Management Properties .

Table Spaces Filters

The filters appearing just above the table allows you to look for specific entry based on some known criteria. You can filter on table and/or database name, and choose between showing the table and/or indices.

Table Identification
Table Name	For table entries, this column contains the table name. If the table has one or more partition, the table name can be expanded to show the names of table partitions in this column. For index entries, this column contains the name of the table associated with the index. When the row shows information about a table, clicking this column shows additional information in the Table Usage Drilldown. For index entries, clicking this column shows the Index Usage Drilldown. Clicking a partition the Partition-Table Usage Drilldown.
DB Name	The name of the database to which the table belongs.
Owner	The table owner.
Index Name	The name of the table index.
Ind ID	For index entries, this column contains the ID of the table index. For table entries, this column shows zero ‘0’. For partitions, this column is blank.
Locks Schema/Partition type	For table entries, this column indicates its locking schema: allpages, datapages, or datarows. For partition entries, this column indicates its type: range, hash, list, or roundrobin.
Table Size (MB)	The table size in MB, including the amount of space occupied by the table data and index. Clicking or hovering over this column shows a chart indicating the table size over time.
Statistics
Data/Index Size (MB)	For index entries, this column shows the amount of space occupied by the table index. For table entries, this column shows the amount of space occupied by the table data. Clicking or hovering over this column shows a chart indicating the displayed data or index size over time.
Incremental Delta Size (MB) (1.5 Hours)	The difference in size of the table data and index over the past one and a half hour.
Rows Inserted (1.5 Hours)	The number of rows inserted over the last one and a half hour.
Rows Updated (1.5 Hours)	The number of rows updated over the past one and a half hour.
Rows Deleted (1.5 Hours)	The number of rows deleted over the past one and a half hour.
Rows	For index entries, this column shows zero ‘0’. For table entries, this column shows the number of rows in the table. Clicking or hovering over this column shows a chart indicating the displayed number of table rows over time.
