Reviewing SQL Server Activity for a Specific Instance

The SQL Server Activity view is displayed by clicking a specific instance under the SQL Servers section.

Figure 35. The SQL Server Activity view.

This view allows carrying out the tasks described in the following sections:

•
Viewing instance properties
•
Viewing resource utilization
•
Viewing session details
•
Viewing the instance’s change of size
•
Viewing disk space usage by logical disk
Viewing instance properties

The Instance Properties section contains the following components:

•
Instance indicators — Availability, Version, Up Since, and Response Time.
•
Alarms — the system-related alarms, derived from VMware, which were invoked for the selected instance during the specified time range.
Viewing resource utilization

The Resource Utilization section displays the instance’s utilization of the following resource types: CPU, Network, Memory, and Disk I/O.

For each of the sections, whenever there is an equivalent metric in the Virtual Machine topology, a bar chart is displayed, comparing the average between the period values of the SQL Server instance and the Virtual Machine metrics. The chart displays the selected metric’s values throughout the specified time range, and the table displays the metric’s average value.

Figure 36. Resource utilization chart.

* 
NOTE: For the Memory resource, the table displays the latest memory utilization.

Except Memory, the utilization of each resource category can be seen using several metrics, as listed below.

•
For the CPU resource:
•
Usage (CPU Utilization)
•
Idle
•
For the Network resource:
•
Packets received
•
Packets sent
•
Total packets
•
Packet errors
•
For the Disks resource:
•
Reads
•
Writes
•
I/O errors
•
I/O busy
•
Total files size
Viewing session details

The Session Details (Average) section displays the following summarized data:

•
Total Sessions — the average number of SQL Server processes, both user and system processes.
•
Active Sessions — the number of non-system sessions that are actively processing in SQL Server or that are waiting on locks (blocked).
•
Blocking Sessions — the average number of blocking processes that were collected during the specified time range.
•
Blocked Sessions — the average number of blocked processes that were collected during the specified time range.
•
Deadlocks — the average number of deadlock events that took place during the specified time range, plotted over time.
* 
NOTE: Clicking the icon near each of the numerical values displays a popup with a chart that shows these values plotted over the specified time range. For instances monitored in Foglight for SQL Server mode, a link at the bottom of each popup allows further investigation using the relevant panel in the SQL Activity drilldown.
Viewing the instance’s change of size

The throughputs section contains two bars, which display the instance’s accumulated change of size caused by running SQL queries of the type selected from the Query Type list (Insert, Update, Delete, Select, or All) during the specified time range. The size change is shown using the following indicators:

•
Number of megabytes
•
Number of rows
* 
NOTE: Clicking anywhere on the bar displays a popup. For instances monitored in Foglight for SQL Server mode, a link at the bottom of this popup allows further investigation using the SQL Activity > I/O by File panel.
Viewing disk space usage by logical disk

The Storage section displays, for each of the logical disks, storage-related data about the disk space allocation and utilization by the virtual machine and the SQL Server instance. Virtual machine-related data is retrieved using vFoglight, while SQL Server instance-related data is retrieved using Foglight for SQL Server. Data is displayed in a graphic (bar) and textual formats.

The Disk Space Utilization bar displays the space breakdown of the logical disk into the following categories:

•
Database used space — disk space actually used by the selected instance.
•
Database free space — disk space allocated to the selected instance but not used.
•
Virtual machine used space — total disk space used by the virtual machine out of the entire disk space, excluding space allocated to the selected instance.
•
Virtual Machine free space — total space allocated to the virtual machine but not used, excluding space allocated to the selected instance.

The Virtual Machine section displays the following data regarding the virtual machine’s disk space utilization:

•
Total space — total disk space allocated to the virtual machine.
•
Free space — total disk space allocated but not used. This value is a summary of the database free space and the virtual machine free space.
•
Used space — total disk space used by both the virtual machine and the selected instance.

The Database section displays the following data regarding the SQL Server instance’s disk space utilization:

•
Allocated Space — disk space allocated to the instance
•
Used Space — disk space actually used by the instance
