Accessing and reviewing the Broker Performance View

The AppServer Operational views section allows you to display information about the AppServer broker's performance and the state of the broker's associated servers. Review this data frequently; these details can help you make informed decisions about your use of the broker and server pool controls as discussed earlier in this chapter.

To display and review AppServer Operational views information:

  1. Display the AppServer main page for the AppServer broker instance that you want to review. See the "Accessing OpenEdge resource information" section for the detailed procedure.
  2. Click in the Operational views section to display the AppServer Broker Performance View page. This page is comprised of data summary sections and graphs as shown:
Data summary sections

The summarized display-only text data on this page is comprised of two sections: Broker Requests and Client Connections. Data in both of these text boxes is determined when the page is initialized or refreshed:

Graphs presentation section

The graphs presentation section of the Broker Performance View contains three graphs: AS Broker Request, AS Broker Activity Status, and Client Connections. Provided that data collection is set and the Trend option is selected, the graphically displayed data complements the summarized text data that displays on the AppServer Broker Performance View page. See the "Data collection details" section for details.

One display format for these graphs, as previously shown on the Broker Performance View page, is a line graph. This format measures how a particular broker-related activity has changed over a period of time. Table 4–8 identifies and briefly describes each of these graphs.

Table 4–8: AppServer broker performance-related graphs 
This AppServer broker graph...
Displays two lines...
AS Broker Request
Of broker-related performance data over a specified time period.
The blue line identifies the number of requests that the broker has completed since the last poll; the red line identifies the number of requests that this same broker has received in this time period.
AS Broker Activity Status
Of broker-related performance data over a specified time period. The blue line identifies the percent of requests that the broker has rejected, up to and including the last poll Fathom has completed for this broker resource. The red line identifies the percent of requests in the queue waiting for the broker, up to and including the last poll completed.
Client Connections
Of client connections related to this broker over a specified time period. For example, data displayed might be related to the last polling activity.
The blue line identifies the client total number of connections requested; the red line identifies the number of clients currently connected to this broker.

Note: It is possible for this graph to accurately show that the number of current connections is higher than the total number of connections. The Clients Total reflects only new connections over the specified time period. In contrast, the Clients Current reflects all current connections, both newly connected and those that might still be connected from a previous polling period, in place when the graph is displayed.

See the "Changing OpenEdge pinup graphical displays" section for details about changing the data appearance of graphs.
