Compare Web Activities

With the Compare Transaction bar chart (ANALYZE > Graphs > Combined Bar Charts > Compare Transactions) you can view the performance of multiple web activities based on a Web Applications.

Tip

This graph is useful because … you can compare web-based transactions under a single transaction filter. That way you can, for example, detect if a specific element of a web request takes longer to access than other elements.

• Transaction filter: List of defined transaction filters that contain data.

Important

What's a transaction filter?

It’s a definition of things to look out for in a web request—for example images so that you can measure how long it takes before all images on a web page are available for the user to view in his or her browser. Transaction filters are very flexible: PerformanceGuard administrators can define more or less any element of a web request as a thing to look out for.

• Server & Port: Select required server and port combination.

Caution

You can only select server/port combinations for which the selected transaction filter has yielded results. Therefore, the option All does not include every server/port combination known by PerformanceGuard, but only all server/port combinations for which the selected transaction has yielded results.

• X-axis Min and Max: Enter the required range for the bar chart’s horizontal axis. If you leave the fields empty, the range will automatically reflect the minimum and maximum values found in the data.
• Type: Determines which type of data the bar chart will contain. You can view descriptions of the available types in Graph Terms and Definitions.
• Agents: Select the group of computers that the bar chart should be based on. Super groups, that is groups of groups, are enclosed in <>.
• Interval: Select the period of time that the graph should cover. If the predefined intervals don’t suit you, select Custom to Custom Time Periods on Graphs.
• Transaction: Select one or more transaction tags from the selected transaction filter. To select multiple tags, press CTRL on your keyboard while you select.

Important

What's a transaction tag?

The PerformanceGuard agents installed on your organization’s computers look out for the things that your transaction filter specifies. When an agent detects one of those things, it generates a transaction tag and sends it to PerformanceGuard so that you are able to select it when you want to view a transaction graph or create SLA items. In other words, a transaction tag is a thing to look out for that one or more agents have positively found.

Important

What if there are no tags to select?

If there are no tags to select, it’s simply because none of the selected computers have made a web request that matches the selected transaction filter. When no computers have made such web requests, the PerformanceGuard agents on the computers have not yet generated any transaction tags, and that’s the reason why there are not any tags that you can select.

Tip

In the PerformanceGuard web interface you can also Web Activities (Time View) in transaction response times, availability, etc. as well as Web Activities (Time View) (that is transaction data that hasn’t been aggregated into trend data).
