IBM Tivoli Composite Application Manager for Transactions, Version 7.4.0.0

Transactions: Summary

This workspace provides general information about the performance of transactions on your managed system. Use this information to monitor transactions and determine if they have any problems.

Using this workspace

This workspace acts as a summary workspace for its category, and provides general information about transactions within applications, components, servers, or transactions. It contains four views in addition to the standard Navigator view:

Lowest Availability
Largest Time Deviation
Largest Transaction Rate Deviation
A summary table called Applications, Components, Servers, or Transactions depending on the category you select.

Figure 1. The Summary workspace

Use the Lowest Availability view to monitor whether transactions of a specific application, component, or server are slow or have failed. The data in this graph measures transactions that occurred during the last aggregation period. The default aggregation period is five minutes. The results of these queries are not sorted. The bars on the graph are color coded:

Red indicates failed transactions
Yellow indicates transactions that are running slow
Green indicates good transactions.

If you move your mouse over different colored categories within a bar, hover help will indicate the relative percentage of that category. Right-click on the bar to link to more detailed workspaces for a particular application, component, server, or transaction.

Use the Largest Time Deviation view to determine which applications have the largest time deviation from a set baseline value. Positive numbers indicate transactions taking more time than the baseline value, and negative numbers indicate transactions taking less time than the baseline value. A deviation of zero indicates either that there is no deviation or that the deviation has not yet been measured.

Use the Largest Transaction Rate Deviation view to determine a deviation in the number of transactions of an application from its baseline value. Positive numbers indicate more transactions than the baseline value, and negative numbers indicate fewer transactions than the baseline value. A deviation of zero indicates either that there is no deviation or that the deviation has not yet been measured. The results of these queries are not sorted.

Depending on the category you select, the Applications, Components, Servers, or Transactions view provides a table that you can use to monitor the transactions on your applications. Table 1 describes the fields in this table.

Table 1. Transaction Interaction Information table
Column	Description
Name	The name of the Application, Component, Server, or Transaction.
Total Time	Measures the average time for a transaction to complete, in milliseconds. The value in this column does not include the time taken for failures, unless all transactions have failed. The Total Time measures the following transactions based on which category you are looking at: For Applications, it measures the average of all the transactions that make up an application. For Components, it measures the average of all the transactions within a component. For Servers, it measures the average of all the transactions on a server. For Transactions, it measures the average of all the transaction instances that make up the specific transaction.
Total Time Deviation	Measures the percentage deviation from a baseline value. Positive numbers indicate a slower total time than the baseline value, and negative numbers indicate a faster total time than the baseline value. A deviation of zero indicates either that there is no deviation or that the deviation has not yet been measured.
Transaction Rate	Measures the average rate of transactions. This is measured in transactions per minute. The Transaction Rate calculates the following rate of transactions based on which category you are looking at: For Applications, it calculates the sum of all transaction instances of the transactions within an application. For Components, it calculates the sum of all transaction instances of all the transactions within a component. For Servers, it calculates the sum of all transaction instances of all the transactions on a server. For Transactions, it calculates the average number of transaction instances of a specific transaction.
Transaction Rate Deviation	Measures the percentage deviation from a baseline value in the number of transactions. Positive numbers indicate more transactions than the baseline value, and negative numbers indicate fewer transactions than the baseline value. A deviation of zero indicates either that there is no deviation or that the deviation has not yet been measured.
Percent Failed	Indicates the percentage of transaction instances that have failed.
Percent Slow	Indicates the percentage of transaction instances that are running slower than a preset threshold.
Percent Good	Indicates the percentage of transaction instances that are running faster than a preset threshold.
Timestamp	Indicates the start time of the period of aggregation.
Enclosing Component	Enclosing component aggregate if applicable.
Enclosing Server	Enclosing server aggregate if applicable.

Accessing this workspace

Access this workspace by clicking on a category in the Navigator view, or by right-clicking a specific application, component, server, or transaction.

Links to other workspaces

From this workspace, you can link to the Interaction by Time workspace, Interaction by Transaction Rate workspace, and Detail workspace, by right-clicking a bar in a graph or clicking a link icon in the table and selecting Link To. You can also view a more detailed Topology workspace for a specific application, component, server, or transaction by clicking the link icon in the table. These workspaces provide more detailed information for a particular application, component, server, or transaction. In addition, you can link to a more detailed category workspace, except in the Transactions category as this is the most detailed level to view transactions.

Note: You can also select the Interaction by Time workspaces and Interaction by Transaction Rate workspaces by right-clicking a category in the Navigator view and selecting Workspace. In this case, these workspaces display all the transaction interactions for a category.

You can select two extra detailed workspaces by clicking a link icon in the table view in the Transactions Summary workspace, the Transaction Instances workspace and the Historical Transaction Instances workspace. These are specific to the Transactions Summary workspace, and are not available from the other summary workspaces.
