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 transaction filter.

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

   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.

  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 & 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 specify your own interval.

• Transaction: Select one or more transaction tags from the selected transaction filter. To select multiple tags, press CTRL on your keyboard while you select.

   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.

   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.
