Workload analysis previews
Preview the workload analysis results to review the process-wise resource consumption of the workloads. These previews show data according to the specified interval and filters. The Preview tab displays the following results:
Review and revise your workload definitions till you obtain the required results in the previews.
Server Summary
The Server Summary preview lets you to analyze the capacity-specific parameters of the selected servers, such as CPU, memory, and disk I/O. The following table describes the columns in the preview:
Column | Description |
|---|---|
Server | The host name of the server. |
CPU Model | The model of the CPU. Note: Some of the CPU model names that are retrieved are different from the names given by the vendors. For example, A G40 HP model shows up as 867. Consult the vendor for more information. |
Vendor | The CPU vendor name. |
OS | The operating system that is running on the server. |
Physical Processors | The number of physical processors on the server. |
Logical Processors | The number of logical processors on the server. |
CPU Util [%] | The percentage of CPU usage of the server according to the number of processors. |
Out of [%] | The percentage of out-of-memory occurrences on the server. |
Queue Length | The average number of transactions that are queued for the CPU service at a time. This number includes the transactions that are being processed and waiting to be processed. |
CPU Capture Ratio | The capture ratio measures the effectiveness of your workload definition. The capture ratio that is close to 1 indicates that your workload definition is able to effectively model the work done on the systems. If the capture ratio differs from 1 considerably, you need to revise the definition. |
Memory [GB] | The total memory available on the server. |
Total Disk IO [pages/sec] | The number of pages that are read and written per second to all the disks on the server. This number includes the input and output operations that occur for paging and transactions on the other servers. |
Paging IO [pages/sec] | The number of input and output operations that occur for paging logical volumes on the server. |
Throughput [trans/hour] | The number of transactions on the server that are processed per hour. |
Run Summary
The Run Summary preview shows the run interval and timestamp for the collected data. The following table describes the columns in the preview:
Column | Description |
|---|---|
Server | The host name of the server. |
Collect version | The version of the collect component. |
Collect Data Repository | The directory for storing the UDR data collected by the Agents. |
Collect Start Time | The time when the data collection was started. |
Collect End Time | The time when the data collection was finished. |
Collect Time Zone | The time zone of the server from which data is collected. |
Analyze Version | The version of the Analyze component. |
Analyze Run Time | The date and time when the workload analysis was run. |
Analyze Start Time | The time when the workload analysis was started. |
Analyze End Time | The time when the workload analysis was finished. |
Interval Length [sec] | The duration of the analysis interval in seconds. |
Workload Composition
The Workload Composition preview lets you assess the effectiveness of the workload definition. If the previews shows lot of zzz, it indicates that the workload definition needs to be revised. The following table describes the columns in the preview:
Column | Description |
|---|---|
Server | The name of the server. |
Workload | The name of the workload. |
Users | The list of users. |
Transaction | The name of the transaction. |
Processes Included Directly | The names of processes that are included in the transaction directly. |
Processes Included by Promotion | The names of the child processes that are included in the transaction by promotion, which is based on the selected rule. By default, processes with the same UID are included. The other possible values are all the child processes and none. |
Full Command Included Directly | Process instances that are specified by the names of the processes and the full commands that started the processes included directly in a transaction. |
Full Command Included by Promotion | Process instances that are specified by the names of processes and the full commands that started the processes included in a transaction by promotion. Inclusion by promotion is based on the include rule that you select. The default rule is "Include if a process has the same UID". The other possible rules are "none" and "all children." |
CPU Util [%] | The percentage of CPU that is used by the workload. |
Throughput [trans/hour] | The transaction throughput in the transactions completed per hour. The transactions counted in the throughput are those transactions that ran on the server and called by local or remote users or transactions. |
Process Details
The Process Details preview provides information about important CPU consumers. The following table describes the columns in the preview:
Column | Description |
|---|---|
Server | The name of the server. |
OS | The type of operating system that is running on the server. |
PID | The process ID. |
Process | The name of the process. |
Parent PID | The ID of the parent process. |
User | The name of the process owner. |
Workload | The name of the workload. |
CPU Time [sec] | The duration in seconds when the CPU was used. |
CPU Util [%] | The percentage of CPU usage. |
Page Faults [ops/sec] | The number of page faults that occurred per second. |
Resident Set [MB] | The amount of physical CPU in MB that is assigned to the process. |
Start Time | The start time of the process. |
